TODO update + internals: changed order or ImGuiLayoutType enums to allow using them for indexing.

- Fixed abnormally high atlas height. (#618)
- Fixed support for any values of TexGlyphPadding (not just only 1). (#618)
- Atlas width is now properly based on total surface rather than glyph count (unless overridden with TexDesiredWidth). (#618)
- Fixed atlas builder so missing glyphs won't influence the atlas texture width. (#2233, #618)
- Fixed atlas builder so duplicate glyphs (when merging fonts) won't be included in the rasterized atlas. (#618)

-ImGui is a bloat-free graphical user interface library for C++. It outputs vertex buffers that you can render in your 3D-pipeline enabled application. It is portable, renderer agnostic and carries minimal amount of dependencies. It is based on an "immediate" graphical user interface paradigm which enables you to build user interfaces with ease.
-
-ImGui is designed to enable fast iteration and allow programmers to create "content creation" or "debug" tools (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal, and thus lacks certain features normally found in more high-level libraries.
-
-ImGui is particularly suited to integration in realtime 3D applications, fullscreen applications, embedded applications, games, or any applications on consoles platforms where operating system features are non-standard. pa
-
-ImGui is self-contained within 6 files that you can easily copy and compile into your application/engine:
-
-  - imgui.cpp
-  - imgui.h
-  - imconfig.h (empty by default, user-editable)
-  - stb_rect_pack.h
-  - stb_textedit.h
-  - stb_truetype.h
-
-Your code passes mouse/keyboard inputs and settings to ImGui (see example applications for more details). After ImGui is setup, you can use it like in this example:
-
-![screenshot of sample code alongside its output with ImGui](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/code_sample_01.png)
-
-ImGui outputs vertex buffers and simple command-lists that you can render in your application. Because it doesn't know or touch graphics state directly, you can call ImGui commands anywhere in your code (e.g. in the middle of a running algorithm, or in the middle of your own rendering process). Refer to the sample applications in the examples/ folder for instructions on how to integrate ImGui with your existing codebase. 
-
-ImGui allows you create elaborate tools as well as very short-lived ones. On the extreme side of short-liveness: using the Edit&Continue feature of compilers you can add a few widgets to tweaks variables while your application is running, and remove the code a minute later! ImGui is not just for tweaking values. You can use it to trace a running algorithm by just emitting text commands. You can use it along with your own reflection data to browse your dataset live. You can use it to expose the internals of a subsystem in your engine, to create a logger, an inspection tool, a profiler, a debugger, etc.

-ImGui can load TTF fonts. UTF-8 is supported for text display and input. Here using Arial Unicode font to display Japanese. Initialize custom font with:
-```
-ImGuiIO& io = ImGui::GetIO();
-io.Fonts->AddFontFromFileTTF("ArialUni.ttf", 18.0f, io.Fonts->GetGlyphRangesJapanese());
-```
-For Microsoft IME, pass your HWND to enable IME positioning:
-```
-io.ImeWindowHandle = my_hwnd;
-```

-Frequently Asked Question
--------------------------
-
-<b>Where is the documentation?</b>
-
-- The documentation is at the top of imgui.cpp + effectively imgui.h.
-- Example code is in the ImGui::ShowTestWindow() function. It covers most features of ImGui so you can read the code and call the function itself to see its output. 
-- Standalone example applications using OpenGL/DirectX are provided in the examples/ folder. 
-
-<b>How do you use ImGui on a platform that may not have a mouse or keyboard?</b>
-
-I recommend using [Synergy](http://synergy-project.org) ([sources](https://github.com/synergy/synergy)). In particular, the _src/micro/uSynergy.c_ file contains a small client that you can use on any platform to connect to your host PC. You can seamlessly use your PC input devices from a video game console or a tablet. ImGui allows to increase the hit box of widgets (via the _TouchPadding_ setting) to accomodate a little for the lack of precision of touch inputs, but it is recommended you use a mouse to allow optimising for screen real-estate.
-
-<b>I integrated ImGui in my engine and the text or lines are blurry..</b>
-
-In your Render function, try translating your projection matrix by (0.5f,0.5f) or (0.375f,0.375f).
-
-<b>Can you create elaborate/serious tools with ImGui?</b>
-
-Yes. I have written data browsers, debuggers, profilers and all sort of non-trivial tools with the library. In my experience the simplicity of the API is very empowering. Your UI runs close to your live data. Make the tools always-on and everybody in the team will be inclined to create new tools (as opposed to more "offline" UI toolkits where only a fraction of your team effectively creates tools).
-
-However note that ImGui is programmer centric and the immediate-mode GUI paradigm might requires a bit of adaptation before you can realize its full potential. Many programmers have unfortunately been taught by their environment to make complicated unproductive things. Strip yourself out of all those heavy layers and start making lots of useful tools!
-
-<b>Is ImGui fast?</b>
-
-Down to the fundation of its visual design, ImGui is engineered to be fairly performant both in term of CPU and GPU usage. Running elaborate code and creating elaborate UI will of course have a cost but ImGui aims to minimize it.
-
-Mileage may vary but the following screenshot can give you a rough idea of the cost of running and rendering UI code (In the case of a trivial demo application like this one, your driver/os setup are likely to be the bottleneck. Testing performance as part of a real application is recommended).
-
-![performance screenshot](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v138/performance_01.png)
-
-This is showing framerate for the full application loop on my 2011 iMac running Windows 7, OpenGL, AMD Radeon HD 6700M with an optimized executable. In contrast, librairies featuring higher-quality rendering and layouting techniques may have a higher resources footprint.
-
-If you intend to display large lists of items (say, 1000+) it can be beneficial for your code to perform clipping manually - using helpers such as ImGuiListClipper - in order to avoid submitting them to ImGui in the first place. Even though ImGui will discard your clipped items it still needs to calculate their size and that overhead will add up if you have thousands of items. If you can handle clipping and height positionning yourself then browsing a list with millions of items isn't a problem.
-
-<b>Can you reskin the look of ImGui?</b>
-
-You can alter the look of the interface to some degree: changing colors, sizes, padding, rounding, fonts. However, as ImGui is designed and optimised to create debug tools, the amount of skinning you can apply is limited. There is only so much you can stray away from the default look and feel of the interface. 
-
-<b>Why using C++ (as opposed to C)?</b>
-
-ImGui takes advantage of a few C++ features for convenience but nothing anywhere Boost-insanity/quagmire. In particular, function overloading and default parameters are used to make the API easier to use and code more terse. Doing so I believe the API is sitting on a sweet spot and giving up on those features would make the API more cumbersome. Other features such as namespace, constructors and templates (in the case of the ImVector<> class) are also relied on as a convenience but could be removed.
-
-Shall someone really need to use ImGui from another language, there is an unofficial but reasonably maintained [c-api for ImGui](https://github.com/Extrawurst/cimgui) by Stephan Dilly. I would suggest using your target language functionality to try replicating the function overloading and default parameters used in C++ else the API may be harder to use. It was really designed with C++ in mind and may not make the same amount of sense with another language.

+
+Dear ImGui is a bloat-free graphical user interface library for C++. It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline enabled application. It is fast, portable, renderer agnostic and self-contained (no external dependencies).
+
+Dear ImGui is designed to enable fast iterations and to empower programmers to create content creation tools and visualization / debug tools (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal, and lacks certain features normally found in more high-level libraries.
+
+Dear ImGui is particularly suited to integration in games engine (for tooling), real-time 3D applications, fullscreen applications, embedded applications, or any applications on consoles platforms where operating system features are non-standard. 
+
+See [Software using dear imgui](https://github.com/ocornut/imgui/wiki/Software-using-dear-imgui), [Quotes](https://github.com/ocornut/imgui/wiki/Quotes) and [Gallery](https://github.com/ocornut/imgui/issues/2265) pages to get an idea of its use cases.
+
+Dear ImGui is self-contained within a few files that you can easily copy and compile into your application/engine:
+- imgui.cpp
+- imgui.h
+- imgui_demo.cpp
+- imgui_draw.cpp
+- imgui_widgets.cpp
+- imgui_internal.h
+- imconfig.h (empty by default, user-editable)
+- imstb_rectpack.h
+- imstb_textedit.h
+- imstb_truetype.h
+
+No specific build process is required. You can add the .cpp files to your project or #include them from an existing file.
+
+### Usage
+
+Your code passes mouse/keyboard/gamepad inputs and settings to Dear ImGui (see example applications for more details). After Dear ImGui is setup, you can use it from \_anywhere\_ in your program loop:
+
+Code:
+```cpp
+ImGui::Text("Hello, world %d", 123);
+if (ImGui::Button("Save"))
+{
+    // do stuff
+}
+ImGui::InputText("string", buf, IM_ARRAYSIZE(buf));
+ImGui::SliderFloat("float", &f, 0.0f, 1.0f);
+```
+Result:
+<br>![sample code output](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v160/code_sample_02.png)
+<br>_(settings: Dark style (left), Light style (right) / Font: Roboto-Medium, 16px / Rounding: 5)_
+
+Code:
+```cpp
+// Create a window called "My First Tool", with a menu bar.
+ImGui::Begin("My First Tool", &my_tool_active, ImGuiWindowFlags_MenuBar);
+if (ImGui::BeginMenuBar())
+{
+    if (ImGui::BeginMenu("File"))
+    {
+        if (ImGui::MenuItem("Open..", "Ctrl+O")) { /* Do stuff */ }
+        if (ImGui::MenuItem("Save", "Ctrl+S"))   { /* Do stuff */ }
+        if (ImGui::MenuItem("Close", "Ctrl+W"))  { my_tool_active = false; }
+        ImGui::EndMenu();
+    }
+    ImGui::EndMenuBar();
+}
+
+// Edit a color (stored as ~4 floats)
+ImGui::ColorEdit4("Color", my_color);
+
+// Plot some values
+const float my_values[] = { 0.2f, 0.1f, 1.0f, 0.5f, 0.9f, 2.2f };
+ImGui::PlotLines("Frame Times", my_values, IM_ARRAYSIZE(my_values));
+ 
+// Display contents in a scrolling region
+ImGui::TextColored(ImVec4(1,1,0,1), "Important Stuff");
+ImGui::BeginChild("Scrolling");
+for (int n = 0; n < 50; n++)
+    ImGui::Text("%04d: Some text", n);
+ImGui::EndChild();
+ImGui::End();
+```
+Result:
+<br>![sample code output](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v160/code_sample_03_color.gif)
+
+### How it works
+
+Check out the References section if you want to understand the core principles behind the IMGUI paradigm. An IMGUI tries to minimize superfluous state duplication, state synchronization and state retention from the user's point of view. It is less error prone (less code and less bugs) than traditional retained-mode interfaces, and lends itself to create dynamic user interfaces. 
+
+Dear ImGui outputs vertex buffers and command lists that you can easily render in your application. The number of draw calls and state changes required to render them is fairly small. Because Dear ImGui doesn't know or touch graphics state directly, you can call its functions  anywhere in your code (e.g. in the middle of a running algorithm, or in the middle of your own rendering process). Refer to the sample applications in the examples/ folder for instructions on how to integrate dear imgui with your existing codebase. 
+
+_A common misunderstanding is to mistake immediate mode gui for immediate mode rendering, which usually implies hammering your driver/GPU with a bunch of inefficient draw calls and state changes as the gui functions are called. This is NOT what Dear ImGui does. Dear ImGui outputs vertex buffers and a small list of draw calls batches. It never touches your GPU directly. The draw call batches are decently optimal and you can render them later, in your app or even remotely._
+
+Dear ImGui allows you create elaborate tools as well as very short-lived ones. On the extreme side of short-liveness: using the Edit&Continue (hot code reload) feature of modern compilers you can add a few widgets to tweaks variables while your application is running, and remove the code a minute later! Dear ImGui is not just for tweaking values. You can use it to trace a running algorithm by just emitting text commands. You can use it along with your own reflection data to browse your dataset live. You can use it to expose the internals of a subsystem in your engine, to create a logger, an inspection tool, a profiler, a debugger, an entire game making editor/framework, etc.  
+
+Demo Binaries
+-------------
+
+You should be able to build the examples from sources (tested on Windows/Mac/Linux). If you don't, let me know! If you want to have a quick look at some Dear ImGui features, you can download Windows binaries of the demo app here:
+- [imgui-demo-binaries-20181008.zip](http://www.miracleworld.net/imgui/binaries/imgui-demo-binaries-20181008.zip) (Windows binaries, Dear ImGui 1.66 WIP built 2018/10/08, master branch, 5 executables)
+
+The demo applications are unfortunately not yet DPI aware so expect some blurriness on a 4K screen. For DPI awareness in your application, you can load/reload your font at different scale, and scale your Style with `style.ScaleAllSizes()`.
+
+Bindings
+--------
+
+Integrating Dear ImGui within your custom engine is a matter of 1) wiring mouse/keyboard/gamepad inputs 2) uploading one texture to your GPU/render engine 3) providing a render function that can bind textures and render textured triangles. The [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder is populated with applications doing just that. If you are an experienced programmer at ease with those concepts, it should take you about an hour to integrate Dear ImGui in your custom engine. Make sure to spend time reading the FAQ, the comments and other documentation!
+
+_NB: those third-party bindings may be more or less maintained, more or less close to the original API (as people who create language bindings sometimes haven't used the C++ API themselves.. for the good reason that they aren't C++ users). Dear ImGui was designed with C++ in mind and some of the subtleties may be lost in translation with other languages. If your language supports it, I would suggest replicating the function overloading and default parameters used in the original, else the API may be harder to use. In doubt, please check the original C++ version first!_

+
+Frequently Asked Question (FAQ)
+-------------------------------
+
+**Where is the documentation?**
+
+- The documentation is at the top of imgui.cpp + effectively imgui.h. 
+- Example code is in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function. It covers most features of ImGui so you can read the code and call the function itself to see its output. 
+- Standalone example applications using e.g. OpenGL/DirectX are provided in the examples/ folder. 
+- We obviously needs better documentation! Consider contributing or becoming a [Patron](http://www.patreon.com/imgui) to promote this effort.
+- Your programming IDE is your friend, find the type or function declaration to find comments associated to it. 
+
+**Which version should I get?**
+
+I occasionally tag [Releases](https://github.com/ocornut/imgui/releases) but it is generally safe and recommended to sync to master/latest. The library is fairly stable and regressions tend to be fixed fast when reported. 
+
+You may also peak at the [Multi-Viewport](https://github.com/ocornut/imgui/issues/1542) and [Docking](https://github.com/ocornut/imgui/issues/2109) branches. Even though they are marked beta, several projects are using them and they are kept in sync with master regularly.
+
+**Who uses Dear ImGui?**
+
+See the [Quotes](https://github.com/ocornut/imgui/wiki/Quotes) and [Software using dear imgui](https://github.com/ocornut/imgui/wiki/Software-using-dear-imgui) pages for an (incomplete) list of games/software which are publicly known to use dear imgui. Please add yours if you can!
+
+**Why the odd dual naming, "Dear ImGui" vs "ImGui"?**
+
+The library started its life and is best known as "ImGui" only due to the fact that I didn't give it a proper name when I released it. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations. It seemed confusing and unfair to hog the name. To reduce the ambiguity without affecting existing codebases, I have decided on an alternate, longer name "dear imgui" that people can use to refer to this specific library in ambiguous situations.
+
+**How can I tell whether to dispatch mouse/keyboard to imgui or to my application?**
+<br>**How can I display an image? What is ImTextureID, how does it works?**
+<br>**How can I have multiple widgets with the same label or with an empty label? A primer on labels and the ID Stack.**
+<br>**How can I use my own math types instead of ImVec2/ImVec4?**
+<br>**How can I load a different font than the default?**
+<br>**How can I easily use icons in my application?**
+<br>**How can I load multiple fonts?**
+<br>**How can I display and input non-latin characters such as Chinese, Japanese, Korean, Cyrillic?** ([example](https://github.com/ocornut/imgui/wiki/Loading-Font-Example))
+<br>**How can I interact with standard C++ types (such as std::string and std::vector)?**
+<br>**How can I use the drawing facilities without an Dear ImGui window? (using ImDrawList API)**
+<br>**How can I use this without a mouse, without a keyboard or without a screen? (gamepad, input share, remote display)**
+<br>**I integrated Dear ImGui in my engine and the text or lines are blurry..**
+<br>**I integrated Dear ImGui in my engine and some elements are disappearing when I move windows around..**
+<br>**How can I help?**
+
+See the FAQ in imgui.cpp for answers.
+
+**Can you create elaborate/serious tools with Dear ImGui?**
+
+Yes. People have written game editors, data browsers, debuggers, profilers and all sort of non-trivial tools with the library. In my experience the simplicity of the API is very empowering. Your UI runs close to your live data. Make the tools always-on and everybody in the team will be inclined to create new tools (as opposed to more "offline" UI toolkits where only a fraction of your team effectively creates tools). The list of sponsors below is also an indicator that serious game teams have been using the library.
+
+Dear ImGui is very programmer centric and the immediate-mode GUI paradigm might requires you to readjust some habits before you can realize its full potential. Dear ImGui is about making things that are simple, efficient and powerful.
+
+**Can you reskin the look of Dear ImGui?**
+
+You can alter the look of the interface to some degree: changing colors, sizes, padding, rounding, fonts. However, as Dear ImGui is designed and optimized to create debug tools, the amount of skinning you can apply is limited. There is only so much you can stray away from the default look and feel of the interface. Below is a screenshot from [LumixEngine](https://github.com/nem0/LumixEngine) with custom colors + a docking/tabs extension (both of which you can find in the Issues section and will eventually be merged):
+
+![LumixEngine](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v151/lumix-201710-rearranged.png)
+
+**Why using C++ (as opposed to C)?**
+
+Dear ImGui takes advantage of a few C++ languages features for convenience but nothing anywhere Boost-insanity/quagmire. Dear ImGui does NOT require C++11 so it can be used with most old C++ compilers. Dear ImGui doesn't use any C++ header file. Language-wise, function overloading and default parameters are used to make the API easier to use and code more terse. Doing so I believe the API is sitting on a sweet spot and giving up on those features would make the API more cumbersome. Other features such as namespace, constructors and templates (in the case of the ImVector<> class) are also relied on as a convenience.
+
+There is an auto-generated [c-api for Dear ImGui (cimgui)](https://github.com/cimgui/cimgui) by Sonoro1234 and Stephan Dilly. This is designed for binding other languages. If possible, I would suggest using your target language functionalities to try replicating the function overloading and default parameters used in C++ else the API may be harder to use. Also see [Bindings](https://github.com/ocornut/imgui/wiki/Bindings) for third-party bindings to other languages.

+
+Developed by [Omar Cornut](http://www.miracleworld.net) and every direct or indirect contributors to the GitHub. The early version of this library was developed with the support of [Media Molecule](http://www.mediamolecule.com) and first used internally on the game [Tearaway](http://tearaway.mediamolecule.com). 
+
+I first discovered the IMGUI paradigm at [Q-Games](http://www.q-games.com) where Atman had dropped his own simple implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating on it.

+ISSUES & TODO LIST
+
+Issue numbers (#) refer to github issues listed at https://github.com/ocornut/imgui/issues/XXXX
+The list below consist mostly of ideas noted down before they are requested/discussed by users (at which point they usually exist on the github issue tracker).
+It's mostly a bunch of personal notes, probably incomplete. Feel free to query if you have any questions.
+
+ - doc/test: add a proper documentation+regression testing system (#435)
+ - doc/test: checklist app to verify binding/integration of imgui (test inputs, rendering, callback, etc.).
+ - doc/tips: tips of the day: website? applet in imgui_club?
+
+ - window: calling SetNextWindowSize() every frame with <= 0 doesn't do anything, may be useful to allow (particularly when used for a single axis). (#690)
+ - window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. perhaps a lightweight explicit cleanup pass.
+ - window: auto-fit feedback loop when user relies on any dynamic layout (window width multiplier, column) appears weird to end-user. clarify.
+ - window: allow resizing of child windows (possibly given min/max for each axis?.)
+ - window: background options for child windows, border option (disable rounding).
+ - window: begin with *p_open == false could return false.
+ - window: get size/pos helpers given names (see discussion in #249)
+ - window: a collapsed window can be stuck behind the main menu bar?
+ - window: when window is very small, prioritize resize button over close button.
+ - window: detect extra End() call that pop the "Debug" window out and assert at End() call site instead of at end of frame.
+ - window: increase minimum size of a window with menus or fix the menu rendering so that it doesn't look odd.
+ - window: double-clicking on title bar to minimize isn't consistent, perhaps move to single-click on left-most collapse icon?
+ - window: expose contents size. (#1045)
+ - window: using SetWindowPos() inside Begin() and moving the window with the mouse reacts a very ugly glitch. We should just defer the SetWindowPos() call.
+ - window: GetWindowSize() returns (0,0) when not calculated? (#1045)
+ - window: investigate better auto-positioning for new windows.
+ - window/opt: freeze window flag: if not focused/hovered, return false, render with previous ImDrawList. and/or reduce refresh rate. 
+ - window/child: the first draw command of a child window could be moved into the current draw command of the parent window (unless child+tooltip?).
+ - window/clipping: some form of clipping when DisplaySize (or corresponding viewport) is zero.
+ - scrolling: while holding down a scrollbar, try to keep the same contents visible (at least while not moving mouse)
+ - scrolling: allow immediately effective change of scroll after Begin() if we haven't appended items yet.
+ - scrolling/clipping: separator on the initial position of a window is not visible (cursorpos.y <= clippos.y). (2017-08-20: can't repro)
+ - scrolling/style: shadows on scrollable areas to denote that there is more contents
+
+ - drawdata: make it easy to clone (or swap?) a ImDrawData so user can easily save that data if they use threaded rendering.
+ - drawlist: end-user probably can't call Clear() directly because we expect a texture to be pushed in the stack.
+ - drawlist: maintaining bounding box per command would allow to merge draw command when clipping isn't relied on (typical non-scrolling window or non-overflowing column would merge with previous command).
+ - drawlist: primitives/helpers to manipulate vertices post submission, so e.g. a quad/rect can be resized to fit later submitted content, _without_ using the ChannelSplit api
+ - drawlist: make it easier to toggle AA per primitive, so we can use e.g. non-AA fill + AA borders more naturally
+ - drawlist: non-AA strokes have gaps between points (#593, #288), especially RenderCheckmark().
+ - drawlist: would be good to be able to deep copy of ImDrawData (we have a deep copy of ImDrawList now).
+ - drawlist: rendering: provide a way for imgui to output to a single/global vertex buffer, re-order indices only at the end of the frame (ref: https://gist.github.com/floooh/10388a0afbe08fce9e617d8aefa7d302)
+ - drawlist: callback: add an extra void* in ImDrawCallback to allow passing render-local data to the callback (would break API).
+ - drawlist/opt: store rounded corners in texture to use 1 quad per corner (filled and wireframe) to lower the cost of rounding. (#1962)
+ - drawlist/opt: AddRect() axis aligned pixel aligned (no-aa) could use 8 triangles instead of 16 and no normal calculation.
+
+ - main: considering adding an Init() function? some constructs are awkward in the implementation because of the lack of them.
+ - main: find a way to preserve relative orders of multiple reappearing windows (so an app toggling between "modes" e.g. fullscreen vs all tools) won't lose relative ordering.
+ - main: IsItemHovered() make it more consistent for various type of widgets, widgets with multiple components, etc. also effectively IsHovered() region sometimes differs from hot region, e.g tree nodes
+ - main: IsItemHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode?
+ - main: rename the main "Debug" window to avoid ID collision with user who may want to use "Debug" with specific flags.
+
+ - widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc. (#395)
+ - widgets: clean up widgets internal toward exposing everything and stabilizing imgui_internals.h.
+ - widgets: add visuals for Disabled/ReadOnly mode and expose publicly (#211)
+ - widgets: add always-allow-overlap mode.
+ - widgets: start exposing PushItemFlag() and ImGuiItemFlags
+ - widgets: alignment options in style (e.g. center Selectable, Right-Align within Button, etc.) #1260
+ - widgets: activate by identifier (trigger button, focus given id)
+ - widgets: a way to represent "mixed" values, so e.g. all values replaced with **, including check-boxes, colors, etc. with support for multi-components widgets (e.g. SliderFloat3, make only "Y" mixed)
+
+ - input text: clean up the mess caused by converting UTF-8 <> wchar. the code is rather inefficient right now and super fragile. 
+ - input text: reorganize event handling, allow CharFilter to modify buffers, allow multiple events? (#541)
+ - input text: expose CursorPos in char filter event (#816)
+ - input text: access public fields via a non-callback API e.g. InputTextGetState("xxx") that may return NULL if not active.
+ - input text: flag to disable live update of the user buffer (also applies to float/int text input) (#701)
+ - input text: hover tooltip could show unclamped text
+ - input text: option to Tab after an Enter validation.
+ - input text: add ImGuiInputTextFlags_EnterToApply? (off #218)
+ - input text: easier ways to update buffer (from source char*) while owned. preserve some sort of cursor position for multi-line text.
+ - input text: add discard flag (e.g. ImGuiInputTextFlags_DiscardActiveBuffer) or make it easier to clear active focus for text replacement during edition (#725)
+ - input text: display bug when clicking a drag/slider after an input text in a different window has all-selected text (order dependent). actually a very old bug but no one appears to have noticed it.
+ - input text: allow centering/positioning text so that ctrl+clicking Drag or Slider keeps the textual value at the same pixel position.
+ - input text: what's the easiest way to implement a nice IP/Mac address input editor?
+ - input text: Global callback system so user can plug in an expression evaluator easily.
+ - input text multi-line: don't directly call AddText() which does an unnecessary vertex reserve for character count prior to clipping. and/or more line-based clipping to AddText(). and/or reorganize TextUnformatted/RenderText for more efficiency for large text (e.g TextUnformatted could clip and log separately, etc).
+ - input text multi-line: support for cut/paste without selection (cut/paste the current line)
+ - input text multi-line: line numbers? status bar? (follow up on #200)
+ - input text multi-line: behave better when user changes input buffer while editing is active (even though it is illegal behavior). namely, the change of buffer can create a scrollbar glitch (#725)
+ - input text multi-line: better horizontal scrolling support (#383, #1224)
+ - input text multi-line: single call to AddText() should be coarse clipped on InputTextEx() end.
+ - input number: optional range min/max for Input*() functions
+ - input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled)
+ - input number: use mouse wheel to step up/down
+ - input number: applying arithmetics ops (+,-,*,/) messes up with text edit undo stack.
+
+ - layout: helper or a way to express ImGui::SameLine(ImGui::GetCursorStartPos().x + ImGui::CalcItemWidth() + ImGui::GetStyle().ItemInnerSpacing.x); in a simpler manner.
+ - layout: generalization of the above: a concept equivalent to word processor ruler tab stop ~ mini columns (position in X, no clipping implied) (vaguely relate to #267, #395, also what is used internally for menu items)
+ - layout: horizontal layout helper (#97)
+ - layout: horizontal flow until no space left (#404)
+ - layout: more generic alignment state (left/right/centered) for single items?
+ - layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 layout code. item width should include frame padding.
+ - layout: BeginGroup() needs a border option. (~#1496)
+ - layout: vertical alignment of mixed height items (e.g. buttons) within a same line (#1284)
+ 
+ - columns: sizing policy (e.g. for each column: fixed size, %, fill, distribute default size among fills) (#513, #125)
+ - columns: add a conditional parameter to SetColumnOffset() (#513, #125)
+ - columns: headers. re-orderable. (#513, #125)
+ - columns: optional sorting modifiers (up/down), sort list so sorting can be done multi-criteria. notify user when sort order changed.
+ - columns: option to alternate background colors on odd/even scanlines.  
+ - columns: allow columns to recurse. 
+ - columns: allow a same columns set to be interrupted by e.g. CollapsingHeader and resume with columns in sync when moving them. 
+ - columns: separator function or parameter that works within the column (currently Separator() bypass all columns) (#125)
+ - columns: flag to add horizontal separator above/below?
+ - columns/layout: setup minimum line height (equivalent of automatically calling AlignFirstTextHeightToWidgets)
+
+!- color: the color conversion helpers/types are a mess and needs sorting out. 
+ - color: (api breaking) ImGui::ColorConvertXXX functions should be loose ImColorConvertXX to match imgui_internals.h
+
+ - plot: full featured plot/graph api w/ scrolling, zooming etc. all bell & whistle. why not!
+ - plot: PlotLines() should use the polygon-stroke facilities, less vertices (currently issues with averaging normals)
+ - plot: make it easier for user to draw extra stuff into the graph (e.g: draw basis, highlight certain points, 2d plots, multiple plots)
+ - plot: "smooth" automatic scale over time, user give an input 0.0(full user scale) 1.0(full derived from value)
+ - plot: option/feature: draw the zero line
+ - plot: option/feature: draw grid, vertical markers
+ - plot: option/feature: draw unit
+ - plot: add a helper e.g. Plot(char* label, float value, float time_span=2.0f) that stores values and Plot them for you - probably another function name. and/or automatically allow to plot ANY displayed value (more reliance on stable ID)
+
+ - clipper: ability to force display 1 item in the list would be convenient (for patterns where we need to set active id etc.)
+ - clipper: ability to disable the clipping through a simple flag/bool.
+ - clipper: ability to run without knowing full count in advance.
+
+ - splitter/separator: formalize the splitter idiom into an official api (we want to handle n-way split) (#319)
+ 
+ - dock: merge docking branch (#2109)
+ - dock: dock out from a collapsing header? would work nicely but need emitting window to keep submitting the code.
+
+ - tabs: make EndTabBar fail if users doesn't respect BeginTabBar return value, for consistency/future-proofing.
+ - tabs: persistent order/focus in BeginTabBar() api (#261, #351)
+
+ - ext: stl-ish friendly extension (imgui_stl.h) that has wrapper for std::string, std::vector etc.
+
+ - button: provide a button that looks framed. (?)
+ - image/image button: misalignment on padded/bordered button?
+ - image/image button: parameters are confusing, image() has tint_col,border_col whereas imagebutton() has bg_col/tint_col. Even thou they are different parameters ordering could be more consistent. can we fix that?
+ - image button: not taking an explicit id is odd.
+ - slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt()
+ - slider: initial absolute click is imprecise. change to relative movement slider (same as scrollbar). (#1946)
+ - slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate.
+ - slider: tint background based on value (e.g. v_min -> v_max, or use 0.0f either side of the sign)
+ - slider: relative dragging? + precision dragging
+ - slider: step option (#1183)
+ - slider style: fill % of the bar instead of positioning a drag.
+ - knob: rotating knob widget (#942)
+ - drag float: power/logarithmic slider and drags are weird. (#1316)
+ - drag float: up/down axis
+ - drag float: power != 0.0f with current value being outside the the range keeps the value stuck.
+ - drag float: added leeway on edge (e.g. a few invisible steps past the clamp limits)
+
+ - combo: use clipper: make it easier to disable clipper with a single flag.
+ - combo: flag for BeginCombo to not return true when unchanged (#1182)
+ - combo: a way/helper to customize the combo preview (#1658)
+ - combo/listbox: keyboard control. need InputText-like non-active focus + key handling. considering keyboard for custom listbox (pr #203)
+ - listbox: refactor and clean the begin/end api
+ - listbox: multiple selection.
+ - listbox: unselect option (#1208)
+ - listbox: make it easier/more natural to implement range-select (need some sort of info/ref about the last clicked/focused item that user can translate to an index?) (wip stash)
+ - listbox: user may want to initial scroll to focus on the one selected value?
+ - listbox: expose hovered item for a basic ListBox
+ - listbox: keyboard navigation.
+ - listbox: scrolling should track modified selection.
+
+!- popups/menus: clarify usage of popups id, how MenuItem/Selectable closing parent popups affects the ID, etc. this is quite fishy needs improvement! (#331, #402)
+ - popups/modal: make modal title bar blink when trying to click outside the modal
+ - popups: reopening context menu at new position should be the behavior by default? (equivalent to internal OpenPopupEx() with reopen_existing=true) (~#1497)
+ - popups: if the popup functions took explicit ImGuiID it would allow the user to manage the scope of those ID. (#331)
+ - popups: clicking outside (to close popup) and holding shouldn't drag window below.
+ - popups: add variant using global identifier similar to Begin/End (#402)
+ - popups: border options. richer api like BeginChild() perhaps? (#197)
+ - tooltip: drag and drop with tooltip near monitor edges lose/changes its last direction instead of locking one. The drag and drop tooltip should always follow without changing direction.
+ - tooltip: tooltip that doesn't fit in entire screen seems to lose their "last preferred direction" and may teleport when moving mouse.
+ - tooltip: allow to set the width of a tooltip to allow TextWrapped() etc. while keeping the height automatic.
+ - tooltip: tooltips with delay timers? or general timer policy? (instantaneous vs timed): IsItemHovered() with timer + implicit aabb-id for items with no ID. (#1485) 
+ 
+ - menus: calling BeginMenu() twice with a same name doesn't append as Begin() does for regular windows (#1207)
+ - menus: menu bars inside modal windows are acting weird.
+ - status-bar: add a per-window status bar helper similar to what menu-bar does.
+ - shortcuts: local-style shortcut api, e.g. parse "&Save"
+ - shortcuts,menus: global-style shortcut api e.g. "Save (CTRL+S)" -> explicit flag for recursing into closed menu
+ - shortcuts: programmatically access shortcuts "Focus("&Save"))
+ - menus: menu-bar: main menu-bar could affect clamping of windows position (~ akin to modifying DisplayMin)
+ - menus: hovering from menu to menu on a menu-bar has 1 frame without any menu, which is a little annoying. ideally either 0 either longer. 
+
+ - text: selectable text (for copy) as a generic feature (ItemFlags?)
+ - text: proper alignment options in imgui_internal.h
+ - text wrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (#249)
+ - text: it's currently impossible to have a window title with "##". perhaps an official workaround would be nice. \ style inhibitor? non-visible ascii code to insert between #?
+ - text: provided a framed text helper, e.g. https://pastebin.com/1Laxy8bT
+ - text link/url button: underlined. should api expose an ID or use text contents as ID? which colors enum to use?
+
+ - tree node / optimization: avoid formatting when clipped.
+ - tree node: tree-node/header right-most side doesn't take account of horizontal scrolling.
+ - tree node: add treenode/treepush int variants? not there because (void*) cast from int warns on some platforms/settings?
+ - tree node: try to apply scrolling at time of TreePop() if node was just opened and end of node is past scrolling limits?
+ - tree node / selectable render mismatch which is visible if you use them both next to each other (e.g. cf. property viewer)
+ - tree node: tweak color scheme to distinguish headers from selected tree node (#581)
+ - tree node: leaf/non-leaf highlight mismatch.
+
+ - settings: write more decent code to allow saving/loading new fields: columns, selected tree nodes?
+ - settings: api for per-tool simple persistent data (bool,int,float,columns sizes,etc.) in .ini file (#437)
+ - stb: add defines to disable stb implementations
+
+ - style: better default styles. (#707)
+ - style: add a highlighted text color (for headers, etc.)
+ - style: border types: out-screen, in-screen, etc. (#447)
+ - style: add window shadow (fading away from the window. Paint-style calculation of vertices alpha after drawlist would be easier)
+ - style: a concept of "compact style" that the end-user can easily rely on (e.g. PushStyleCompact()?) that maps to other settings? avoid implementing duplicate helpers such as SmallCheckbox(), etc.
+ - style: try to make PushStyleVar() more robust to incorrect parameters (to be more friendly to edit & continues situation).
+ - style: global scale setting.
+ - style: WindowPadding needs to be EVEN as the 0.5 multiplier used on this value probably have a subtle effect on clip rectangle
+ - style: have a more global HSV setter (e.g. alter hue on all elements). consider replacing active/hovered by offset in HSV space? (#438, #707, #1223)
+ - style: gradients fill (#1223) ~ 2 bg colors for each fill? tricky with rounded shapes and using textures for corners.
+ - style editor: color child window height expressed in multiple of line height.
+
+ - log: LogButtons() options for specifying depth and/or hiding depth slider
+ - log: have more control over the log scope (e.g. stop logging when leaving current tree node scope)
+ - log: be able to log anything (e.g. right-click on a window/tree-node, shows context menu? log into tty/file/clipboard)
+ - log: let user copy any window content to clipboard easily (CTRL+C on windows? while moving it? context menu?). code is commented because it fails with multiple Begin/End pairs.
+
+ - filters: set a current filter that tree node can automatically query to hide themselves
+ - filters: handle wild-cards (with implicit leading/trailing *), reg-exprs
+ - filters: fuzzy matches (may use code at blog.forrestthewoods.com/4cffeed33fdb)
+
+ - drag and drop: releasing a drop shows the "..." tooltip for one frame - since e13e598 (#1725)
+ - drag and drop: have some way to know when a drag begin from BeginDragDropSource() pov.
+ - drag and drop: allow preview tooltip to be submitted from a different place than the drag source. (#1725)
+ - drag and drop: allow using with other mouse buttons (where activeid won't be set). (#1637)
+ - drag and drop: make it easier and provide a demo to have tooltip both are source and target site, with a more detailed one on target site (tooltip ordering problem)
+ - drag and drop: test with reordering nodes (in a list, or a tree node). (#143)
+ - drag and drop: test integrating with os drag and drop (make it easy to do a naive WM_DROPFILE integration)
+ - drag and drop: make payload optional? (#143)
+ - drag and drop: feedback when hovering a modal (cursor?)
+ - node/graph editor (#306)
+ - pie menus patterns (#434)
+ - markup: simple markup language for color change? (#902)
+
+ - font: MergeMode: flags to select overwriting or not (this is now very easy with refactored ImFontAtlasBuildWithStbTruetype)
+ - font: free the Alpha buffer if user only requested RGBA.
+!- font: better CalcTextSizeA() API, at least for simple use cases. current one is horrible (perhaps have simple vs extended versions).
+ - font: a CalcTextHeight() helper could run faster than CalcTextSize().y
+ - font: enforce monospace through ImFontConfig (for icons?) + create dual ImFont output from same input, reusing rasterized data but with different glyphs/AdvanceX
+ - font: finish CustomRectRegister() to allow mapping Unicode codepoint to custom texture data 
+ - font: PushFontSize API (#1018)
+ - font: MemoryTTF taking ownership confusing/not obvious, maybe default should be opposite?
+ - font/demo: add tools to show glyphs used by a text blob, display U16 value, list missing glyphs.
+ - font/demo: demonstrate use of ImFontGlyphRangesBuilder.
+ - font/atlas: add a missing Glyphs.reserve()
+ - font/atlas: incremental updates
+ - font/atlas: dynamic font atlas to avoid baking huge ranges into bitmap and make scaling easier.
+ - font/atlas: allow user to submit its own primitive to be rectpacked, and allow to map them on a Unicode point.
+ - font/draw: vertical and/or rotated text renderer (#705) - vertical is easier clipping wise
+ - font/draw: need to be able to specify wrap start position.
+ - font/draw: better reserve policy for large horizontal block of text (shouldn't reserve for all clipped lines)
+ - font: optimization: for monospace font (like the default one) we can trim IndexXAdvance as long as trailing value is == FallbackXAdvance (need to make sure TAB is still correct), would save on cache line.
+ - font: add support for kerning, probably optional. A) perhaps default to (32..128)^2 matrix ~ 9K entries = 36KB, then hash for non-ascii?. B) or sparse lookup into per-char list?
+ - font: add a simpler CalcTextSizeA() api? current one ok but not welcome if user needs to call it directly (without going through ImGui::CalcTextSize)
+ - font: fix AddRemapChar() to work before font has been built.
+ - font: what would it take to support codepoint higher than 0xFFFF? (smileys, etc.)
+ - font: (api breaking) remove "TTF" from symbol names. also because it now supports OTF.
+ - font/opt: Considering storing standalone AdvanceX table as 16-bit fixed point integer?
+ - font/opt: Glyph currently 40 bytes (2+9*4). Consider storing UV as 16 bits integer? (->32 bytes). X0/Y0/X1/Y1 as 16 fixed-point integers? Or X0/Y0 as float and X1/Y1 as fixed8_8?
+
+ - nav: NavScrollToBringItemIntoView() with item bigger than view should focus top-right? Repro: using Nav in "About Window"
+ - nav: wrap around logic to allow e.g. grid based layout (pressing NavRight on the right-most element would go to the next row, etc.). see internal's NavMoveRequestTryWrapping().
+ - nav: patterns to make it possible for arrows key to update selection
+ - nav: restore/find nearest navid when current one disappear (e.g. pressed a button that disappear, or perhaps auto restoring when current button change name)
+ - nav: SetItemDefaultFocus() level of priority, so widget like Selectable when inside a popup could claim a low-priority default focus on the first selected iem
+ - nav: allow input system to be be more tolerant of io.DeltaTime=0.0f
+ - nav: ESC within a menu of a child window seems to exit the child window.
+ - nav: NavFlattened: ESC on a flattened child should select something.
+ - nav: NavFlattened: broken: in typical usage scenario, the items of a fully clipped child are currently not considered to enter into a NavFlattened child.
+ - nav: NavFlattened: init request doesn't select items that are part of a NavFlattened child
+ - nav: NavFlattened: cannot access menu-bar of a flattened child window with Alt/menu key (not a very common use case..).
+ - nav: Left within a tree node block as a fallback (ImGuiTreeNodeFlags_NavLeftJumpsBackHere by default?)
+ - nav/menus: pressing left-right on a vertically clipped menu bar tends to jump to the collapse/close buttons.
+ - nav/menus: allow pressing Menu to leave a sub-menu.
+ - nav/menus: a way to access the main menu bar with Alt? (currently needs CTRL+TAB)
+ - nav/menus: when using the main menu bar, even though we restore focus after, the underlying window loses its title bar highlight during menu manipulation. could we prevent it?
+ - nav: simulate right-click or context activation? (SHIFT+F10)
+ - nav: tabs should go through most/all widgets (in submission order?).
+ - nav: when CTRL-Tab/windowing is active, the HoveredWindow detection doesn't take account of the window display re-ordering.
+ - nav: esc/enter default behavior for popups, e.g. be able to mark an "ok" or "cancel" button that would get triggered by those keys.
+ - nav: when activating a button that changes label (without a static ID) or disappear, can we somehow automatically recover into a nearest highlight item?
+ - nav: there's currently no way to completely clear focus with the keyboard. depending on patterns used by the application to dispatch inputs, it may be desirable.
+ - nav: configuration flag to disable global shortcuts (currently only CTRL-tab) ?
+ - focus: preserve ActiveId/focus stack state, e.g. when opening a menu and close it, previously selected InputText() focus gets restored (#622)
+ - focus: SetKeyboardFocusHere() on with >= 0 offset could be done on same frame (else latch and modulate on beginning of next frame)
+ - focus: unable to use SetKeyboardFocusHere() on clipped widgets. (#787)
+
+ - inputs: we need an explicit flag about whether the imgui window is focused, to be able to distinguish focused key releases vs alt-tabbing all release behaviors.
+ - inputs: rework IO system to be able to pass actual ordered/timestamped events. use an event queue? (~#335, #71)
+ - inputs: support track pad style scrolling & slider edit.
+ - inputs/io: backspace and arrows in the context of a text input could use system repeat rate.
+ - inputs/io: clarify/standardize/expose repeat rate and repeat delays (#1808)
+
+ - misc: idle: expose "woken up" boolean (set by inputs) and/or animation time (for cursor blink) for back-end to be able stop refreshing easily.
+ - misc: idle: if cursor blink if the _only_ visible animation, core imgui could rewrite vertex alpha to avoid CPU pass on ImGui:: calls.
+ - misc: make the ImGuiCond values linear (non-power-of-two). internal storage for ImGuiWindow can use integers to combine into flags (Why?)
+ - misc: provide a way to compile out the entire implementation while providing a dummy API (e.g. #define IMGUI_DUMMY_IMPL)
+ - misc: PushItemFlag(): add a flag to disable keyboard capture when used with mouse? (#1682)
+ - misc: use more size_t in public api?
+
+ - backend: bgfx? https://gist.github.com/RichardGale/6e2b74bc42b3005e08397236e4be0fd0
+ - web/emscriptem: refactor some examples to facilitate integration with emscripten main loop system. (#1713, #336)
+ - web/emscriptem: with refactored examples, we could provide a direct imgui_impl_emscripten platform layer (see eg. https://github.com/floooh/sokol-samples/blob/master/html5/imgui-emsc.cc#L42)
+
+ - remote: make a system like RemoteImGui first-class citizen/project (#75)
+
+ - demo: find a way to demonstrate textures in the examples application, as it such a a common issue for new users.
+ - demo: add vertical separator demo
+ - demo: add virtual scrolling example?
+ - demo: demonstrate Plot offset
+ - examples: window minimize, maximize (#583)
+ - examples: provide a zero frame-rate/idle example.
+ - examples: apple: example_apple should be using modern GL3.
+ - examples: glfw: could go idle when minimized? if (glfwGetWindowAttrib(window, GLFW_ICONIFIED)) { glfwWaitEvents(); continue; } // issue: DeltaTime will be super high on resume, perhaps provide a way to let impl know (#440)
+ - optimization: replace vsnprintf with stb_printf? or enable the defines/infrastructure to allow it (#1038)
+ - optimization: add clipping for multi-component widgets (SliderFloatX, ColorEditX, etc.). one problem is that nav branch can't easily clip parent group when there is a move request.
+ - optimization: add a flag to disable most of rendering, for the case where the user expect to skip it (#335)
+ - optimization: fully covered window (covered by another with non-translucent bg + WindowRounding worth of padding) may want to clip rendering.
+ - optimization: use another hash function than crc32, e.g. FNV1a
+ - optimization/render: merge command-lists with same clip-rect into one even if they aren't sequential? (as long as in-between clip rectangle don't overlap)?
+ - optimization: turn some the various stack vectors into statically-sized arrays

+-----------------------------------------------------------------------
+ examples/README.txt

+-----------------------------------------------------------------------
 
-TL;DR; 
- Refer to 'opengl_example' (not 'opengl3_example') to understand how the library is setup.
- Copy the imgui_impl_xxx.cpp/.h file you need if you are using one of the rendering backend used in an example.
- If you are using a different or your own backend, copy opengl_example/imgui_impl_opengl.cpp/.h to get started.

-ImGui is highly portable and only requires a few things to run:
  - Providing mouse/keyboard inputs
- - Load the font atlas texture into GPU memory
- - Providing a render function to process the drawing commands (we rendere indexed textured triangles)
- - Extra just as clipboard support, mouse cursor supports, Windows IME support.
-So this is essentially what those examples are doing + the obligatory cruft for portability.
+ - Uploading the font atlas texture into graphics memory
+ - Providing a render function to render indexed textured triangles
+ - Optional: clipboard support, mouse cursor supports, Windows IME support, etc.
 
-Unfortunately in 2015 it is still a massive pain to create and maintain portable build files using
-external library like the ones we're using here. 
-For most example here I choose to provide Visual Studio 10 .sln files and Makefile for Linux/OSX. 
-Please let me know if they don't work with your setup!
-You can probably just import the imgui_impl_xxx.cpp/.h files into your own codebase or compile those
-directly with a command-line compiler.
+This is essentially what the example bindings in this folder are providing + obligatory portability cruft.
 
-opengl_example/
-    OpenGL example, using GLFW + fixed pipeline.
-    This is simple and should work for all OpenGL enabled applications.
-    Prefer following this example to learn how ImGui works!
+It is important to understand the difference between the core Dear ImGui library (files in the root folder)
+and examples bindings which we are describing here (examples/ folder).
+You should be able to write bindings for pretty much any platform and any 3D graphics API. With some extra
+effort you can even perform the rendering remotely, on a different machine than the one running the logic.
 
-opengl3_example/
-    OpenGL example, using GLFW/GL3W + programmable pipeline.
-    This uses more modern OpenGL calls and custom shaders.
-    Even if your application is using modern OpenGL you are better off copying the code from the fixed pipeline version!
-    I don't think there is an advantage using this over the simpler example, but it is provided for reference.
+This folder contains two things:
 
-directx9_example/
+ - Example bindings for popular platforms/graphics API, which you can use as is or adapt for your own use.
+   They are the imgui_impl_XXXX files found in the examples/ folder.
+
+ - Example applications (standalone, ready-to-build) using the aforementioned bindings.
+   They are the in the XXXX_example/ sub-folders.
+
+You can find binaries of some of those example applications at: 
+  http://www.miracleworld.net/imgui/binaries
+
+
+---------------------------------------
+ MISC COMMENTS AND SUGGESTIONS
+---------------------------------------
+
+ - Please read 'PROGRAMMER GUIDE' in imgui.cpp for notes on how to setup Dear ImGui in your codebase.
+   Please read the comments and instruction at the top of each file.
+   
+ - If you are using of the backend provided here, so you can copy the imgui_impl_xxx.cpp/h files
+   to your project and use them unmodified. Each imgui_impl_xxxx.cpp comes with its own individual
+   ChangeLog at the top of the .cpp files, so if you want to update them later it will be easier to
+   catch up with what changed.
+
+ - Dear ImGui has 0 to 1 frame of lag for most behaviors, at 60 FPS your experience should be pleasant.
+   However, consider that OS mouse cursors are typically drawn through a specific hardware accelerated path
+   and will feel smoother than common GPU rendered contents (including Dear ImGui windows). 
+   You may experiment with the io.MouseDrawCursor flag to request Dear ImGui to draw a mouse cursor itself, 
+   to visualize the lag between a hardware cursor and a software cursor. However, rendering a mouse cursor
+   at 60 FPS will feel slow. It might be beneficial to the user experience to switch to a software rendered
+   cursor only when an interactive drag is in progress. 
+   Note that some setup or GPU drivers are likely to be causing extra lag depending on their settings.
+   If you feel that dragging windows feels laggy and you are not sure who to blame: try to build an 
+   application drawing a shape directly under the mouse cursor.
+
+
+---------------------------------------
+ EXAMPLE BINDINGS
+---------------------------------------
+
+Most the example bindings are split in 2 parts:
+
+ - The "Platform" bindings, in charge of: mouse/keyboard/gamepad inputs, cursor shape, timing, windowing.
+   Examples: Windows (imgui_impl_win32.cpp), GLFW (imgui_impl_glfw.cpp), SDL2 (imgui_impl_sdl.cpp)
+
+ - The "Renderer" bindings, in charge of: creating the main font texture, rendering imgui draw data.
+   Examples: DirectX11 (imgui_impl_dx11.cpp), GL3 (imgui_impl_opengl3.cpp), Vulkan (imgui_impl_vulkan.cpp)
+
+ - The example _applications_ usually combine 1 platform + 1 renderer binding to create a working program.
+   Examples: the example_win32_directx11/ application combines imgui_impl_win32.cpp + imgui_impl_dx11.cpp.
+
+ - Some bindings for higher level frameworks carry both "Platform" and "Renderer" parts in one file.
+   This is the case for Allegro 5 (imgui_impl_allegro5.cpp), Marmalade (imgui_impl_marmalade5.cpp).
+
+ - If you use your own engine, you may decide to use some of existing bindings and/or rewrite some using 
+   your own API. As a recommendation, if you are new to Dear ImGui, try using the existing binding as-is
+   first, before moving on to rewrite some of the code. Although it is tempting to rewrite both of the 
+   imgui_impl_xxxx files to fit under your coding style, consider that it is not necessary!
+   In fact, if you are new to Dear ImGui, rewriting them will almost always be harder.
+
+   Example: your engine is built over Windows + DirectX11 but you have your own high-level rendering 
+   system layered over DirectX11.
+     Suggestion: step 1: try using imgui_impl_win32.cpp + imgui_impl_dx11.cpp first. 
+     Once this work, _if_ you want you can replace the imgui_impl_dx11.cpp code with a custom renderer 
+     using your own functions, etc. 
+     Please consider using the bindings to the lower-level platform/graphics API as-is.
+
+   Example: your engine is multi-platform (consoles, phones, etc.), you have high-level systems everywhere.
+     Suggestion: step 1: try using a non-portable binding first (e.g. win32 + underlying graphics API)!
+     This is counter-intuitive, but this will get you running faster! Once you better understand how imgui
+     works and is bound, you can rewrite the code using your own systems.
+
+ - Road-map: Dear ImGui 1.70 (WIP currently in the "viewport" branch) will allows imgui windows to be 
+   seamlessly detached from the main application window. This is achieved using an extra layer to the 
+   platform and renderer bindings, which allows imgui to communicate platform-specific requests.
+   If you decide to use unmodified imgui_impl_xxxx.cpp files, you will automatically benefit from 
+   improvements and fixes related to viewports and platform windows without extra work on your side.

+---------------------------------------
+ EXAMPLE APPLICATIONS
+---------------------------------------
+
+Building:
+  Unfortunately in 2018 it is still tedious to create and maintain portable build files using external 
+  libraries (the kind we're using here to create a window and render 3D triangles) without relying on 
+  third party software. For most examples here I choose to provide:
+   - Makefiles for Linux/OSX
+   - Batch files for Visual Studio 2008+
+   - A .sln project file for Visual Studio 2010+ 
+   - Xcode project files for the Apple examples
+  Please let me know if they don't work with your setup!
+  You can probably just import the imgui_impl_xxx.cpp/.h files into your own codebase or compile those
+  directly with a command-line compiler.

+# Configuration
+
+Dear ImGui outputs 16-bit vertex indices by default. 
+Allegro doesn't support them natively, so we have two solutions: convert the indices manually in imgui_impl_allegro5.cpp, or compile imgui with 32-bit indices.
+You can either modify imconfig.h that comes with Dear ImGui (easier), or set a C++ preprocessor option IMGUI_USER_CONFIG to find to a filename.
+We are providing `imconfig_allegro5.h` that enables 32-bit indices.
+Note that the back-end supports _BOTH_ 16-bit and 32-bit indices, but 32-bit indices will be slightly faster as they won't require a manual conversion.
+
+# How to Build
+
+- On Ubuntu 14.04+
+
+```bash
+g++ -DIMGUI_USER_CONFIG=\"examples/example_allegro5/imconfig_allegro5.h\" -I .. -I ../.. main.cpp ..\imgui_impl_allegro5.cpp ../../imgui*.cpp -lallegro -lallegro_primitives -o allegro5_example
+```
+
+- On Windows with Visual Studio's CLI
+
+```
+set ALLEGRODIR=path_to_your_allegro5_folder
+cl /Zi /MD /I %ALLEGRODIR%\include /DIMGUI_USER_CONFIG=\"examples/example_allegro5/imconfig_allegro5.h\" /I .. /I ..\.. main.cpp ..\imgui_impl_allegro5.cpp ..\..\imgui*.cpp /link /LIBPATH:%ALLEGRODIR%\lib allegro-5.0.10-monolith-md.lib user32.lib

+# iOS / OSX Metal example
+
+## Introduction
+
+This example shows how to integrate Dear ImGui with Metal. It is based on the "cross-platform" game template provided with Xcode as of Xcode 9.
+
+(NB: you may still want to use GLFW or SDL which will also support Windows, Linux along with OSX.)
