-## How to create an Issue
-
-Hello! 
-
-You may use the Issue Tracker to submit bug reports, feature requests or suggestions. You may ask for help or advice as well. However please read this wall of text before doing so. The amount of incomplete or ambiguous requests due to people not following those guidelines is often overwhelming. Please do your best to clarify your request. Thank you!
-
-**IF YOU ARE HAVING AN ISSUE COMPILING/LINKING/RUNNING/DISPLAYING/ADDING FONTS/WIRING INPUTS**
-- Please post on the "Getting Started" Discourse forum: https://discourse.dearimgui.org/c/getting-started
-
-**Prerequisites for new users of dear imgui:**
-- Please read the FAQ in imgui.cpp.
-- Please read misc/fonts/README.txt if your question relates to fonts or text.
-- Please run ImGui::ShowDemoWindow() to explore the demo and its sources.
-- Please use the Search function of GitHub to look for similar issues. You may also browse issues by tags.
-- Please use the Search function of your IDE to search in the code for comments related to your situation.
-- If you get a assert, use a debugger to locate the line triggering it and read the comments around the assert.
-
-**Guidelines to report an issue or ask a question:**
-- Please provide your imgui version number.
-- Please state if you have made substantial modifications to your copy of imgui. 
-- Try to be explicit with your expectations and what you have tried. What you have in mind or in your code is not obvious to other people.
-- If you are discussing an assert or a crash, please provide a debugger callstack. Never state "it crashes" without additional information. If you don't know how to use a debugger and retrieve a callstack, learning about it will be useful.
-- Please make sure that your compilation settings have asserts enabled. Calls to IM_ASSERT() are scattered in the code to help catch common issues. By default IM_ASSERT() calls the standard assert() function. To verify that your asserts are enabled, add the line `IM_ASSERT(false);` in your main() function. Your application should display an error message and abort. If your application report an error, it means that your asserts are disabled. Please make sure they are enabled.
-- When discussing issues related to rendering or inputs, please state the OS/back-end/renderer you are using. Please state if you are using a vanilla copy of the example back-ends (imgui_impl_XXX files), or a modified one, or if you built your own.
-- Please provide a Minimal, Complete and Verifiable Example ([MCVE](https://stackoverflow.com/help/mcve)) to demonstrate your problem. An ideal submission includes a small piece of code that anyone can paste in one of the examples/ application (e.g. in main.cpp or imgui_demo.cpp) to understand and reproduce it. Narrowing your problem to its shortest and purest form is the easiest way to understand it. Please test your shortened code to ensure it actually exhibit the problem. Often while creating the MCVE you will end up solving the problem! Many questions that are missing a standalone verifiable example are missing the actual cause of their issue in the description, which ends up wasting everyone's time.
-- Try to attach screenshots to clarify the context. They often convey useful information that are omitted by the description. You can drag pictures/files here (prefer github attachments over 3rd party hosting).
-- When requesting a new feature, please describe the usage context (how you intend to use it, why you need it, etc.).
-
-**Some unfortunate words of warning**
-- If you are or were involved in cheating schemes (e.g. DLL injection) for competitive online multi-player games, please don't post here. We won't answer and you will be blocked. We've had too many of you. Please stop.
-- Due to frequent abuse of this service from aforementioned users, if your GitHub account is anonymous and was created five minutes ago please understand that your post will receive more scrutiny and incomplete questions may be dismissed.
-
-If you have been using dear imgui for a while or have been using C/C++ for several years or have demonstrated good behavior here, it is ok to not fullfill every item to the letter. Those are guidelines and experienced users or members of the community will know what information are useful in a given context.
-
-## How to create an Pull Request
-- When adding a feature, please describe the usage context (how you intend to use it, why you need it, etc.).
-- When fixing a warning or compilation problem, please post the compiler log and specify the version and OS you are using.
-- Try to attach screenshots to clarify the context and demonstrate the feature at a glance. You can drag pictures/files here (prefer github attachments over 3rd party hosting).
-- Make sure your code follows the coding style already used in imgui (spaces instead of tabs, "local_variable", "FunctionName", "MemberName", etc.). We don't use modern C++ idioms and can compile without C++11.
-- Make sure you create a branch for the pull request. In Git, 1 PR is associated to 1 branch. If you keep pushing to the same branch after you submitted the PR, your new commits will appear in the PR (we can still cherry-pick individual commits).

+-----------------------------------------------------------------------
+ VERSION 1.68 (Released 2019-02-19)
+-----------------------------------------------------------------------
+
+Breaking Changes:
+
+- Removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already).
+- Made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame).
+  If for some reason your time step calculation gives you a zero value, replace it with a dummy small value!
+
+Other Changes:
+
+- Added .editorconfig file for text editors to standardize using spaces. (#2038) [@kudaba]
+- ImDrawData: Added FramebufferScale field (currently a copy of the value from io.DisplayFramebufferScale).
+  This is to allow render functions being written without pulling any data from ImGuiIO, allowing incoming
+  multi-viewport feature to behave on Retina display and with multiple displays.
+  If you are not using a custom binding, please update your render function code ahead of time,
+  and use draw_data->FramebufferScale instead of io.DisplayFramebufferScale. (#2306, #1676)
+- Added IsItemActivated() as an extension to the IsItemDeactivated/IsItemDeactivatedAfterEdit functions
+  which are useful to implement variety of undo patterns. (#820, #956, #1875)
+- InputText: Fixed a bug where ESCAPE would not restore the initial value in all situations. (#2321) [@relick]
+- InputText: Fixed a bug where ESCAPE would be first captured by the Keyboard Navigation code. (#2321, #787)
+- InputText: Fixed redo buffer exhaustion handling (rare) which could corrupt the undo character buffer. (#2333)
+  The way the redo/undo buffers work would have made it generally unnoticeable to the user.
+- Fixed range-version of PushID() and GetID() not honoring the ### operator to restart from the seed value.
+- Fixed CloseCurrentPopup() on a child-menu of a modal incorrectly closing the modal. (#2308)
+- Tabs: Added ImGuiTabBarFlags_TabListPopupButton flag to show a popup button on manual tab bars. (#261, #351)
+- Tabs: Removed ImGuiTabBarFlags_NoTabListPopupButton which was available in 1.67 but actually had zero use.
+- Tabs: Fixed a minor clipping glitch when changing style's FramePadding from frame to frame.
+- Tabs: Fixed border (when enabled) so it is aligned correctly mid-pixel and appears as bright as other borders.
+- Style, Selectable: Added ImGuiStyle::SelectableTextAlign and ImGuiStyleVar_SelectableTextAlign. (#2347) [@haldean]
+- Menus: Tweaked horizontal overlap between parent and child menu (to help convey relative depth)
+  from using style.ItemSpacing.x to style.ItemInnerSpacing.x, the later being expected to be smaller. (#1086)
+- RadioButton: Fixed label horizontal alignment to precisely match Checkbox().
+- Window: When resizing from an edge, the border is more visible and better follow the rounded corners.
+- Window: Fixed initial width of collapsed windows not taking account of contents width (broken in 1.67). (#2336, #176)
+- Scrollbar: Fade out and disable interaction when too small, in order to facilitate using the resize grab on very
+  small window, as well as reducing visual noise/overlap.
+- ListBox: Better optimized when clipped / non-visible.
+- InputTextMultiline: Better optimized when clipped / non-visible.
+- Font: Fixed high-level ImGui::CalcTextSize() used by most widgets from erroneously subtracting 1.0f*scale to
+  calculated text width. Among noticeable side-effects, it would make sequences of repeated Text/SameLine calls
+  not align the same as a single call, and create mismatch between high-level size calculation and those performed
+  with the lower-level ImDrawList api. (#792) [@SlNPacifist]
+- Font: Fixed building atlas when specifying duplicate/overlapping ranges within a same font. (#2353, #2233)
+- ImDrawList: Fixed AddCircle(), AddCircleFilled() angle step being off, which was visible when drawing a "circle"
+  with a small number of segments (e.g. an hexagon). (#2287) [@baktery]
+- ImGuiTextBuffer: Added append() function (unformatted).
+- ImFontAtlas: Added 0x2000-0x206F general punctuation range to default ChineseFull/ChineseSimplifiedCommon ranges. (#2093)
+- ImFontAtlas: FreeType: Added support for imgui allocators + custom FreeType only SetAllocatorFunctions. (#2285) [@Vuhdo]
+- ImFontAtlas: FreeType: Fixed using imgui_freetype.cpp in unity builds. (#2302)
+- Demo: Fixed "Log" demo not initializing properly, leading to the first line not showing before a Clear. (#2318) [@bluescan]
+- Demo: Added "Auto-scroll" option in Log/Console demos. (#2300) [@nicolasnoble, @ocornut]
+- Examples: Metal, OpenGL2, OpenGL3, Vulkan: Fixed offsetting of clipping rectangle with ImDrawData::DisplayPos != (0,0)
+  when the display frame-buffer scale scale is not (1,1). While this doesn't make a difference when using master branch,
+  this is effectively fixing support for multi-viewport with Mac Retina Displays on those examples. (#2306) [@rasky, @ocornut]
+  Also using ImDrawData::FramebufferScale instead of io.DisplayFramebufferScale.
+- Examples: Clarified the use the ImDrawData::DisplayPos to offset clipping rectangles.
+- Examples: Win32: Using GetForegroundWindow()+IsChild() instead of GetActiveWindow() to be compatible with windows created
+  in a different thread or parent. (#1951, #2087, #2156, #2232) [many people]
+- Examples: SDL: Using the SDL_WINDOW_ALLOW_HIGHDPI flag. (#2306, #1676) [@rasky]
+- Examples: Win32: Added support for XInput games (if ImGuiConfigFlags_NavEnableGamepad is enabled).
+- Examples: Win32: Added support for mouse buttons 4 and 5 via WM_XBUTTON* messages. (#2264)
+- Examples: DirectX9: Explicitly disable fog (D3DRS_FOGENABLE) before drawing in case user state has it set. (#2288, #2230)
+- Examples: OpenGL2: Added #define GL_SILENCE_DEPRECATION to cope with newer XCode warnings.
+- Examples: OpenGL3: Using GLSL 4.10 shaders for any GLSL version over 410 (e.g. 430, 450). (#2329) [@BrutPitt]
+
+
+-----------------------------------------------------------------------
+ VERSION 1.67 (Released 2019-01-14)
+-----------------------------------------------------------------------
+
+Breaking Changes:
+
+- Made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable
+  side-effect because the window would have ID zero. In particular it is causing problems in viewport/docking branches.
+- Renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges and removed its [Beta] mark.
+  The addition of new configuration options in the Docking branch is pushing for a little reorganization of those names.
+- Renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Keep redirection typedef (will obsolete).
+
+Other Changes:
+- Added BETA api for Tab Bar/Tabs widgets: (#261, #351)
+  - Added BeginTabBar(), EndTabBar(), BeginTabItem(), EndTabItem(), SetTabItemClosed() API.
+  - Added ImGuiTabBarFlags flags for BeginTabBar().
+  - Added ImGuiTabItemFlags flags for BeginTabItem().
+  - Style: Added ImGuiCol_Tab, ImGuiCol_TabHovered, ImGuiCol_TabActive, ImGuiCol_TabUnfocused, ImGuiCol_TabUnfocusedActive colors.
+  - Demo: Added Layout->Tabs demo code.
+  - Demo: Added "Documents" example app showcasing possible use for tabs.
+  This feature was merged from the Docking branch in order to allow the use of regular tabs in your code.
+  (It does not provide the docking/splitting/merging of windows available in the Docking branch)
+- Added ImGuiWindowFlags_UnsavedDocument window flag to append '*' to title without altering the ID, as a convenience
+  to avoid using the ### operator. In the Docking branch this also has an effect on tab closing behavior.
+- Window, Focus, Popup: Fixed an issue where closing a popup by clicking another window with the _NoMove flag would refocus
+  the parent window of the popup instead of the newly clicked window.
+- Window: Contents size is preserved while a window collapsed. Fix auto-resizing window losing their size for one frame when uncollapsed.
+- Window: Contents size is preserved while a window contents is hidden (unless it is hidden for resizing purpose).
+- Window: Resizing windows from edge is now enabled by default (io.ConfigWindowsResizeFromEdges=true). Note that
+  it only works _if_ the back-end sets ImGuiBackendFlags_HasMouseCursors, which the standard back-ends do.
+- Window: Added io.ConfigWindowsMoveFromTitleBarOnly option. This is ignored by window with no title bars (often popups).
+  This affects clamping window within the visible area: with this option enabled title bars need to be visible. (#899)
+- Window: Fixed using SetNextWindowPos() on a child window (which wasn't really documented) position the cursor as expected
+  in the parent window, so there is no mismatch between the layout in parent and the position of the child window.
+- InputFloat: When using ImGuiInputTextFlags_ReadOnly the step buttons are disabled. (#2257)
+- DragFloat: Fixed broken mouse direction change with power!=1.0. (#2174, #2206) [@Joshhua5]
+- Nav: Fixed an keyboard issue where holding Activate/Space for longer than two frames on a button would unnecessary
+  keep the focus on the parent window, which could steal it from newly appearing windows. (#787)
+- Nav: Fixed animated window titles from being updated when displayed in the CTRL+Tab list. (#787)
+- Error recovery: Extraneous/undesired calls to End() are now being caught by an assert in the End() function closer
+  to the user call site (instead of being reported in EndFrame). Past the assert, they don't lead to crashes any more. (#1651)
+  Missing calls to End(), past the assert, should not lead to crashes or to the fallback Debug window appearing on screen.
+  Those changes makes it easier to integrate dear imgui with a scripting language allowing, given asserts are redirected
+  into e.g. an error log and stopping the script execution.
+- ImFontAtlas: Stb and FreeType: Atlas width is now properly based on total surface rather than glyph count (unless overridden with TexDesiredWidth).
+- ImFontAtlas: Stb and FreeType: Fixed atlas builder so missing glyphs won't influence the atlas texture width. (#2233)
+- ImFontAtlas: Stb and FreeType: Fixed atlas builder so duplicate glyphs (when merging fonts) won't be included in the rasterized atlas.
+- ImFontAtlas: FreeType: Fixed abnormally high atlas height.
+- ImFontAtlas: FreeType: Fixed support for any values of TexGlyphPadding (not just only 1).
+- ImDrawList: Optimized some of the functions for performance of debug builds where non-inline function call cost are non-negligible.
+  (Our test UI scene on VS2015 Debug Win64 with /RTC1 went ~5.9 ms -> ~4.9 ms. In Release same scene stays at ~0.3 ms.)
+- IO: Added BackendPlatformUserData, BackendRendererUserData, BackendLanguageUserData void* for storage use by back-ends.
+- IO: Renamed InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead!
+- IO: AddInputCharacter() goes into a queue which can receive as many characters as needed during the frame. This is useful
+  for automation to not have an upper limit on typing speed. Will later transition key/mouse to use the event queue later.
+- Style: Tweaked default value of style.DisplayWindowPadding from (20,20) to (19,19) so the default style as a value
+  which is the same as the title bar height.
+- Demo: "Simple Layout" and "Style Editor" are now using tabs.
+- Demo: Added a few more things under "Child windows" (changing ImGuiCol_ChildBg, positioning child, using IsItemHovered after a child).
+- Examples: DirectX10/11/12: Made imgui_impl_dx10/dx11/dx12.cpp link d3dcompiler.lib from the .cpp file to ease integration.
+- Examples: Allegro 5: Properly destroy globals on shutdown to allow for restart. (#2262) [@DomRe]
+
+
+-----------------------------------------------------------------------
+ VERSION 1.66b (Released 2018-12-01)
+-----------------------------------------------------------------------
+
+Other Changes:
+
+- Fixed a text rendering/clipping bug introduced in 1.66 (on 2018-10-12, commit ede3a3b9) that affect single ImDrawList::AddText()
+  calls with single strings larger than 10k. Text/TextUnformatted() calls were not affected, but e.g. InputText() was. [@pdoane]
+- When the focused window become inactive don't restore focus to a window with the ImGuiWindowFlags_NoInputs flag. (#2213) [@zzzyap]
+- Separator: Fixed Separator() outputting an extraneous empty line when captured into clipboard/text/file.
+- Demo: Added ShowAboutWindow() call, previously was only accessible from the demo window.
+- Demo: ShowAboutWindow() now display various Build/Config Information (compiler, os, etc.) that can easily be copied into bug reports.
+- Fixed build issue with osxcross and macOS. (#2218) [@dos1]
+- Examples: Setting up 'io.BackendPlatformName'/'io.BackendRendererName' fields to the current back-end can be displayed in the About window.
+- Examples: SDL: changed the signature of ImGui_ImplSDL2_ProcessEvent() to use a const SDL_Event*. (#2187)
+
+
+-----------------------------------------------------------------------
+ VERSION 1.66 (Released 2018-11-22)
+-----------------------------------------------------------------------
+
+Breaking Changes:
+
+- Renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete).
+- Renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files. (#2035, #2096)
+
+Other Changes:
+
+- Fixed calling SetNextWindowSize()/SetWindowSize() with non-integer values leading to
+  accidental alteration of window position. We now round the provided size. (#2067)
+- Fixed calling DestroyContext() always saving .ini data with the current context instead
+  of the supplied context pointer. (#2066)
+- Nav, Focus: Fixed ImGuiWindowFlags_NoBringToFrontOnFocus windows not being restoring focus
+  properly after the main menu bar or last focused window is deactivated.
+- Nav: Fixed an assert in certain circumstance (mostly when using popups) when mouse positions stop being valid. (#2168)
+- Nav: Fixed explicit directional input not re-highlighting current nav item if there is a single item in the window
+  and highlight has been previously disabled by the mouse. (#787)
+- DragFloat: Fixed a situation where dragging with value rounding enabled or with a power curve
+  erroneously wrapped the value to one of the min/max edge. (#2024, #708, #320, #2075).
+- DragFloat: Disabled using power curve when one edge is FLT_MAX (broken in 1.61). (#2024)
+- DragFloat: Disabled setting a default drag speed when one edge is FLT_MAX. (#2024)
+- SliderAngle: Added optional format argument to alter precision or localize the string. (#2150) [@podsvirov]
+- Window: Resizing from edges (with io.ConfigResizeWindowsFromEdges Beta flag) extends the hit region
+  of root floating windows outside the window, making it easier to resize windows. Resize grips are also
+  extended accordingly so there are no discontinuity when hovering between borders and corners. (#1495, #822)
+- Window: Added ImGuiWindowFlags_NoBackground flag to avoid rendering window background. This is mostly to allow
+  the creation of new flag combinations, as we could already use SetNextWindowBgAlpha(0.0f). (#1660) [@biojppm, @ocornut]
+- Window: Added ImGuiWindowFlags_NoDecoration helper flag which is essentially NoTitleBar+NoResize+NoScrollbar+NoCollapse.
+- Window: Added ImGuiWindowFlags_NoMouseInputs which is basically the old ImGuiWindowFlags_NoInputs (essentially
+  we have renamed ImGuiWindowFlags_NoInputs to ImGuiWindowFlags_NoMouseInputs). Made the new ImGuiWindowFlags_NoInputs
+  encompass both NoMouseInputs+NoNav, which is consistent with its description. (#1660, #787)
+- Window, Inputs: Fixed resizing from edges when io.MousePos is not pixel-rounded by rounding mouse position input. (#2110)
+- BeginChild(): Fixed BeginChild(const char*, ...) variation erroneously not applying the ID stack
+  to the provided string to uniquely identify the child window. This was undoing an intentional change
+  introduced in 1.50 and broken in 1.60. (#1698, #894, #713).
+- TextUnformatted(): Fixed a case where large-text path would read bytes past the text_end marker depending
+  on the position of new lines in the buffer (it wasn't affecting the output but still not the right thing to do!)
+- ListBox(): Fixed frame sizing when items_count==1 unnecessarily showing a scrollbar. (#2173) [@luk1337, @ocornut]
+- ListBox(): Tweaked frame sizing so list boxes will look more consistent when FramePadding is far from ItemSpacing.
+- RenderText(): Some optimization for very large text buffers, useful for non-optimized builds.
+- BeginMenu(): Fixed menu popup horizontal offset being off the item in the menu bar when WindowPadding=0.0f.
+- ArrowButton(): Fixed arrow shape being horizontally misaligned by (FramePadding.y-FramePadding.x) if they are different.
+- Demo: Split the contents of ShowDemoWindow() into smaller functions as it appears to speed up link time with VS. (#2152)
+- Drag and Drop: Added GetDragDropPayload() to peek directly into the payload (if any) from anywhere. (#143)
+- ImGuiTextBuffer: Avoid heap allocation when empty.
+- ImDrawList: Fixed AddConvexPolyFilled() undefined behavior when passing points_count smaller than 3,
+  in particular, points_count==0 could lead to a memory stomp if the draw list was previously empty.
+- Examples: DirectX10, DirectX11: Removed seemingly unnecessary calls to invalidate and recreate device objects
+  in the WM_SIZE handler. (#2088) [@ice1000]
+- Examples: GLFW: User previously installed GLFW callbacks are now saved and chain-called by the default callbacks. (#1759)
+- Examples: OpenGL3: Added support for GL 4.5's glClipControl(GL_UPPER_LEFT). (#2186)
+- Examples: OpenGL3+GLFW: Fixed error condition when using the GLAD loader. (#2157) [@blackball]
+- Examples: OpenGL3+GLFW/SDL: Made main.cpp compile with IMGUI_IMPL_OPENGL_LOADER_CUSTOM (may be missing init). (#2178) [@doug-moen]
+- Examples: SDL2+Vulkan: Fixed application shutdown which could deadlock on Linux + Xorg. (#2181) [@eRabbit0]
+
+
+-----------------------------------------------------------------------
+ VERSION 1.65 (Released 2018-09-06)
+-----------------------------------------------------------------------
+
+Breaking Changes:
+
+- Renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and
+  stb_rect_pack.h to imstb_rectpack.h. If you were conveniently using the imgui copy of those
+  STB headers in your project, you will have to update your include paths. (#1718, #2036)
+  The reason for this change is to avoid conflicts for projects that may also be importing
+  their own copy of the STB libraries. Note that imgui's copy of stb_textedit.h is modified.
+- Renamed io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427)
+
+Other Changes:
+
+- This is a minor release following the 1.64 refactor, with a little more shuffling of code.
+- Clarified and improved the source code sectioning in all files (easier to search or browse sections).
+- Nav: Removed the [Beta] tag from various descriptions of the gamepad/keyboard navigation system.
+  Although it is not perfect and will keep being improved, it is fairly functional and used by many. (#787)
+- Fixed a build issue with non-Cygwin GCC under Windows.
+- Demo: Added a "Configuration" block to make io.ConfigFlags/io.BackendFlags more prominent.
+- Examples: OpenGL3+SDL2: Fixed error condition when using the GLAD loader. (#2059, #2002) [@jiri]
+
+
+-----------------------------------------------------------------------
+ VERSION 1.64 (Released 2018-08-31)
+-----------------------------------------------------------------------
+
+Changes:
+
+- Moved README, CHANGELOG and TODO files to the docs/ folder.
+  If you are updating dear imgui by copying files, take the chance to delete the old files.
+- Added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp.
+  Re-ordered some of the code remaining in imgui.cpp.
+  NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTIONS HAS BEEN MOVED.
+  Because of this, any local modifications to imgui.cpp will likely conflict when you update.
+  If you have any modifications to imgui.cpp, it is suggested that you first update to 1.63, then
+  isolate your patches. You can peak at imgui_widgets.cpp from 1.64 to get a sense of what is included in it,
+  then separate your changes into several patches that can more easily be applied to 1.64 on a per-file basis.
+  What I found worked nicely for me, was to open the diff of the old patches in an interactive merge/diff tool,
+  search for the corresponding function in the new code and apply the chunks manually.
+- As a reminder, if you have any change to imgui.cpp it is a good habit to discuss them on the github,
+  so a solution applicable on the Master branch can be found. If your company has changes that you cannot
+  disclose you may also contact me privately.
+
+
 -----------------------------------------------------------------------
  VERSION 1.63 (Released 2018-08-29)
 -----------------------------------------------------------------------
 
 Breaking Changes:
 
-- Style: Renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete).

+ VERSION 1.45 (2015-09-01)
+-----------------------------------------------------------------------
+
+Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.45
+
+Breaking Changes:
+
+- With the addition of better horizontal scrolling primitives I had to make some consistency fixes.
+  `GetCursorPos()` `SetCursorPos()` `GetContentRegionMax()` `GetWindowContentRegionMin()` `GetWindowContentRegionMax()`
+  are now incorporating the scrolling amount. They were incorrectly not incorporating this amount previously.
+  It PROBABLY shouldn't break anything, but that depends on how you used them. Namely:
+  - If you always used SetCursorPos() with values relative to GetCursorPos() there shouldn't be a problem.
+    However if you used absolute coordinates, note that SetCursorPosY(100.0f) will put you at +100 from the initial Y position (which may be scrolled out of the view), NOT at +100 from the window top border. Since there wasn't any official scrolling value on X axis (past just manually moving the cursor) this can only affect you if you used to set absolute coordinates on the Y axis which is hopefully rare/unlikely, and trivial to fix.
+  - The value of GetWindowContentRegionMax() isn't necessarily close to GetWindowWidth() if horizontally scrolling.
+    Previously they were roughly interchangeable (roughly because the content region exclude window padding).
+
+Other Changes:
+
+- Added Horizontal Scrollbar via ImGuiWindowFlags_HorizontalScroll (#246).
+- Added GetScrollX(), GetScrollX(), GetScrollMaxX() apis (#246).
+- Added SetNextWindowContentSize(), SetNextWindowContentWidth() to explicitly set the content size of a window, which
+  define the range of scrollbar. When set explicitly it also define the base value from which widget width are derived.
+- Added IO.WantTextInput telling when ImGui is expecting text input, so that e.g. OS on-screen keyboard can be enabled.
+- Added printf attribute to printf-like text formatting functions (Clang/GCC).
+- Added GetMousePosOnOpeningCurrentPopup() helper.
+- Added GetContentRegionAvailWidth() helper.
+- Malformed UTF-8 data don't terminate string, output 0xFFFD instead (#307).
+- ImDrawList: Added AddBezierCurve(), PathBezierCurveTo() API for cubic bezier curves (#311).
+- ImDrawList: Allow to override ImDrawIdx type (#292).
+- ImDrawList: Added an assert on overflowing index value (#292).
+- ImDrawList: Fixed issues with channels split/merge. Now functional without manually adding a draw cmd. Added comments.
+- ImDrawData: Added ScaleClipRects() helper useful when rendering scaled. (#287).
+- Fixed Bullet() inconsistent layout behaviour when clipped.
+- Fixed IsWindowHovered() not taking account of window hoverability (may be disabled because of a popup).
+- Fixed InvisibleButton() not honoring negative size consistently with other widgets that do so.
+- Fixed OpenPopup() accessing current window, effectively opening "Debug" when called from an empty window stack.
+- TreeNode(): Fixed IsItemHovered() result being inconsistent with interaction visuals (#282).
+- TreeNode(): Fixed mouse interaction padding past the node label being accounted for in layout (#282).
+- BeginChild(): Passing a ImGuiWindowFlags_NoMove inhibits moving parent window from this child.
+- BeginChild() fixed missing rounding for child sizes which leaked into layout and have items misaligned.
+- Begin(): Removed default name = "Debug" parameter. We already have a "Debug" window pushed to the stack in the first place so it's not really a useful default.
+- Begin(): Minor fixes with windows main clipping rectangle (e.g. child window with border).
+- Begin(): Window flags are only read on the first call of the frame. Subsequent calls ignore flags, which allows appending to a window without worryin about flags.
+- InputText(): ignore character input when ctrl/alt are held. (Normally those text input are ignored by most wrappers.) (#279).
+- Demo: Fixed incorrectly formed string passed to Combo (#298).
+- Demo: Added simple Log demo.
+- Demo: Added horizontal scrolling example + enabled in console, log and child examples (#246).
+- Style: made scrollbars rounded by default. Because nice. Minor menu bar background alpha tweak. (#246)
+- Metrics: display indices along with triangles count (#299) and some internal state.
+- ImGuiTextFilter::PassFilter() supports string range. Added [] helper to ImGuiTextBuffer.
+- ImGuiTextFilter::Draw() default parameter width=0.0f for no override, allow override with negative values.
+- Examples: OpenGL2/OpenGL3: fix for retina displays. Default font current lack crispness.
+- Examples: OpenGL2/OpenGL3: save/restore more GL state correctly.
+- Examples: DirectX9/DirectX11: resizing buffers dynamically (#299).
+- Examples: DirectX9/DirectX11: added missing middle mouse button to Windows event handler.
+- Examples: DirectX11: fix for Visual Studio 2015 presumably shipping with an updated version of DX11.
+- Examples: iOS: fixed missing files in project.

+-----------------------------------------------------------------------
+ VERSION 1.44 (2015-08-08)
+-----------------------------------------------------------------------
+
+Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.44
+
+Breaking Changes:
+
+- imgui.cpp has been split intro extra files: imgui_demo.cpp, imgui_draw.cpp, imgui_internal.h.
+  Add the two extra .cpp to your project or #include them from another .cpp file. (#219)
+
+Other Changes:
+
+- Internal data structure and several useful functions are now exposed in imgui_internal.h. This should make it easier
+  and more natural to extend ImGui. However please note that none of the content in imgui_internal.h is guaranteed
+  for forward-compatibility and code using those types/functions may occasionally break. (#219)
+- All sample code is in imgui_demo.cpp. Please keep this file in your project and consider allowing your code to call
+  the ShowTestWindow() function as de-facto guide to ImGui features. It will be stripped out by the linker when unused.
+- Added GetContentRegionAvail() helper (basically GetContentRegionMax() - GetCursorPos()).
+- Added ImGuiWindowFlags_NoInputs for totally input-passthru window.
+- Button(): honor negative size consistently with other widgets that do so (width -100 to align the button 100 pixels
+  before the right-most position of the contents region).
+- InputTextMultiline(): honor negative size consistently with other widgets that do so.
+- Combo() clamp popup to lower edge of visible area.
+- InputInt(): value doesn't pass through an int>float>int casting chain, fix handling lost of precision with "large" integer.
+- InputInt() allow hexadecimal input (awkwardly via ImGuiInputTextFlags_CharsHexadecimal but we will allow format
+  string in InputInt* later).
+- Checkbox(), RadioButton(): fixed scaling of checkbox and radio button for the filling of "active" visual.
+- Columns: never assume horizontal space for scrollbar if NoScrollbar flag is explicitly set.
+- Slider: fixed using FramePadding between frame and grab visual. Scaling that spacing would look odd.
+- Fixed lower-right resize grip hit box not scaling along with its rendered size (#287)
+- ImDrawList: Fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (v1.43) being off by an extra PI for no reason.
+- ImDrawList: Added ImDrawList::AddText() shorthand helper.
+- ImDrawList: Add missing support for anti-aliased thick-lines (#133, also ref #288)
+- ImFontAtlas: Added AddFontFromMemoryCompressedBase85TTF() to load base85 encoded font string. Default font encoded
+  as base85 saves ~100 lines / 26 KB of source code. Added base85 output to the binary_to_compressed_c tool.
+- Build fix for MinGW (#276).
+- Examples: OpenGL3: Fixed running on script core profiles for OSX (#277).
+- Examples: OpenGL3: Simplified code using glBufferData for vertices as well (#277, #278)
+- Examples: DirectX11: Clear font texture view to ensure Release() doesn't get called twice (#290).
+- Updated to stb_truetype 1.07 (back to vanilla version as our minor changes are now in master & fix unlikely assert
+  with odd fonts (#280)
+
+
+-----------------------------------------------------------------------
+ VERSION 1.43 (2015-07-17)
+-----------------------------------------------------------------------
+
+Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.43
+
+Breaking Changes:
+
+- This is a rather important release and we unfortunately had to break the rendering API.
+  ImGui now requires you to render indexed vertices instead of non-indexed ones. The fix should be very easy.
+  Sorry for that! This change is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost.
+  Each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles
+  using indices from the index buffer.
+- If you are using a vanilla copy of one of the imgui_impl_XXXX.cpp provided in the example, you just need to update
+  your copy and you can ignore the rest.
+- The signature of the io.RenderDrawListsFn handler has changed
+  From:  ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count)
+  To:    ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data)
+  With:  argument   'cmd_lists'        -> 'draw_data->CmdLists'
+         argument   'cmd_lists_count'  -> 'draw_data->CmdListsCount'
+         ImDrawList 'commands'         -> 'CmdBuffer'
+         ImDrawList 'vtx_buffer'       -> 'VtxBuffer'
+         ImDrawList  n/a               -> 'IdxBuffer' (new)
+         ImDrawCmd  'vtx_count'        -> 'ElemCount'
+         ImDrawCmd  'clip_rect'        -> 'ClipRect'
+         ImDrawCmd  'user_callback'    -> 'UserCallback'
+         ImDrawCmd  'texture_id'       -> 'TextureId'
+- If you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index
+  the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering!
+  Refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. Please upgrade!
+
+Other Changes:
+
+- Added anti-aliasing on lines and shapes based on primitives by @MikkoMononen (#133).
+  Between the use of indexed-rendering and the fact that the entire rendering codebase has been optimized and massaged
+  enough, with anti-aliasing enabled ImGui 1.43 is now running FASTER than 1.41.
+  Made some extra effort in making the code run faster in your typical Debug build.
+- Anti-aliasing can be disabled in the ImGuiStyle structure via the AntiAliasedLines/AntiAliasedShapes fields for further gains.
+- ImDrawList: Added AddPolyline(), AddConvexPolyFilled() with optional anti-aliasing.
+- ImDrawList: Added stateful path building and stroking API. PathLineTo(), PathArcTo(), PathRect(), PathFill(), PathStroke()
+  with optional anti-aliasing.
+- ImDrawList: Added AddRectFilledMultiColor() helper.
+- ImDrawList: Added multi-channel rendering so out of order elements can be rendered in separate channels and then merged
+  back together (used by columns).
+- ImDrawList: Fixed merging draw commands when equal clip rectangles are in the two first commands.
+- ImDrawList: Fixed window draw lists not destructed properly on Shutdown().
+- ImDrawData: Added DeIndexAllBuffers() helper.
+- Added lots of new font options ImFontAtlas::AddFont() and the new ImFontConfig structure.
+  - Added support for oversampling (ImFontConfig: OversampleH, OversampleV) and sub-pixel positioning (ImFontConfig: PixelSnapH).
+    Oversampling allows sub-pixel positioning but can also be used as a way to get some leeway with scaling fonts without re-rasterizing.
+  - Added GlyphExtraSpacing option to add extra horizontal spacing between characters (#242).
+  - Added MergeMode option to merge glyphs from different font inputs into a same font (#182, #232).
+  - Added FontDataOwnedByAtlas option to keep ownership from the TTF data buffer and request the atlas to make a copy (#220).
+- Updated to stb_truetype 1.06 (+ minor mods) with better font rasterization.
+- InputText: Added ImGuiInputTextFlags_NoHorizontalScroll flag.
+- InputText: Added ImGuiInputTextFlags_AlwaysInsertMode flag.
+- InputText: Added HasSelection() helper in ImGuiTextEditCallbackData as a clarification.
+- InputText: Fix for using END key on a multi-line text editor (#275)
+- Columns: Dispatch render of each column in a sub-draw list and merge on closure, saving a lot of draw calls! (#125)
+- Popups: Fixed Combo boxes inside menus. (#272)
+- Style: Added GrabRounding setting to make the sliders etc. grabs rounded.
+- Changed SameLine() parameters from int to float.
+- Fixed incorrect assert triggering when code stole ActiveID from user moving a window by calling e.g. SetKeyboardFocusHere().
+- Fixed CollapsingHeader() label rendering outside its frame in columns context where ClipRect max isn't aligned with the
+  right-side of the header.
+- Metrics window: calculate bounding box of actual vertices when hovering a draw list.
+- Examples: Showing more information in the Fonts section.
+- Examples: Added a gratuitous About window.
+- Examples: Updated all examples code (OpenGL/DX9/DX11/SDL/Allegro/iOS) to use indexed rendering.
+- Examples: Fixed the SDL2 example to support Unicode text input (#274).

+
+-----------------------------------------------------------------------
+ VERSION 1.42 (2015-07-08)
+-----------------------------------------------------------------------
+
+Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.42
+
+Breaking Changes:
+
+- Renamed SetScrollPosHere() to SetScrollHere(). Kept inline redirection function (will obsolete).
+- Renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion and make scrolling API consistent,
+  because positions (e.g. cursor position) are not equivalent to scrolling amount.
+- Removed obsolete GetDefaultFontData() function that would assert anyway.
+  If you are updating from <1.30 you'll get a compile error instead of an assertion. (obsoleted 2015/01/11)
+
+Other Changes:
+
+- Added SDL2 example application (courtesy of @CedricGuillemet)
+- Added iOS example application (courtesy of @joeld42)
+- Added Allegro 5 example application (courtesy of @bggd)
+- Added TitleBgActive color in style so focused window is made visible. (#253)
+- Added CaptureKeyboardFromApp() / CaptureMouseFromApp() to manually enforce inputs capturing.
+- Added DragFloatRange2() DragIntRange2() helpers. (#76)
+- Added a Y centering ratio to SetScrollFromCursorPos() which can be used to aim the top or bottom of the window. (#150)
+- Added SetScrollY(), SetScrollFromPos(), GetCursorStartPos() for manual scrolling manipulations. (#150).
+- Added GetKeyIndex() helper for converting from ImGuiKey_\* enum to user's keycodes. Basically pulls from io.KeysMap[].
+- Added missing ImGuiKey_PageUp, ImGuiKey_PageDown so more UI code can be written without referring to implementation-side keycodes.
+- MenuItem() can be activated on release. (#245)
+- Allowing NewFrame() with DeltaTime==0.0f to not assert.
+- Fixed IsMouseDragging(). (#260)
+- Fixed PlotLines(), PlotHistogram() using incorrect hovering test so they would show their tooltip even when there is
+  a popup between mouse and the graph.
+- Fixed window padding being reported incorrectly for child windows with borders when parent have no borders.
+- Fixed a bug with TextUnformatted() clipping of long text blob when clipping y1 line sits on the first line of text. (#257)
+- Fixed text baseline alignment of small button (no padding) after regular buttons.
+- Fixed ListBoxHeader() not honoring negative sizes the same way as BeginChild() or BeginChildFrame(). (#263)
+- Fixed warnings for more pedantic compiler settings (#258).
+- ImVector<> cannot be re-defined anymore, cannot be replaced with std::vector<>. Allowed us to clean up and optimize
+  lots of code. Yeah! (#262)
+- ImDrawList: store pointer to their owner name for easier auditing/debugging.
+- Examples: added scroll tracking example with SetScrollFromCursorPos().
+- Examples: metrics windows render clip rectangle when hovering over a draw call.
+- Lots of small optimization (particularly to run faster on unoptimized builds) and tidying up.
+- Added font links in extra_fonts/ + instructions for using compressed fonts in C array.
+
+
+-----------------------------------------------------------------------
+ VERSION 1.41 (2015-06-26)
+-----------------------------------------------------------------------
+
+Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.41
+
+Breaking Changes:
+
+- Changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent).
+  Only makes a difference when texture have transparency.
+- Changed Selectable() API from (label, selected, size) to (label, selected, flags, size).
+  Size override should be used very rarely so hopefully it doesn't affect many people. Sorry!
+
+Other Changes:
+
+- Added InputTextMultiline() multi-line text editor, vertical scrolling, selection, optimized enough to handle rather
+  big chunks of text in stateless context (thousands of lines are ok), option for allowing Tab to be input, option
+  for validating with Return or Ctrl+Return (#200).
+- Added modal window API, BeginPopupModal(), follows the popup api scheme. Modal windows can be closed by clicking
+  outside. By default the rest of the screen is dimmed (using ImGuiCol_ModalWindowDarkening). Modal windows can be stacked.
+- Added GetGlyphRangesCyrillic() helper (#237).
+- Added SetNextWindowPosCenter() to center a window prior to knowing its size. (#249)
+- Added IsWindowHovered() helper.
+- Added IsMouseReleased(), IsKeyReleased() helpers to allow to user to avoid tracking them. (#248)
+- Allow Set*WindowSize() calls to be used with popups.
+- Window: AutoFit can be triggered on each axis separately via SetNextWindowSize(), etc.
+- Window: fixed scrolling with mouse wheel while window was collapsed.
+- Window: fixed mouse wheel scroll issues.
+- DragFloat(), SliderFloat(): Fixed rounding of negative numbers which sometime made the negative lower bound unreachable.
+- InputText(): lifted character count limit.
+- InputText(): fixes in case of using per-window font scaling.
+- Selectable(), MenuItem(): do not use frame rounding for hovering/selection.
+- Selectable(): Added flag ImGuiSelectableFlags_DontClosePopups.
+- Selectable(): Added flag ImGuiSelectableFlags_SpanAllColumns (#125).
+- Combo(): Fixed issue with activating a Combo() not taking active id (#241).
+- ColorButton(), ColorEdit4(): fix to ensure that the colored square stays square when non-default padding settings are used.
+- BeginChildFrame(): returns bool like BeginChild() for clipping.
+- SetScrollPosHere(): takes account of item height + more accurate centering + fixed precision issue.
+- ImFont: ignoring '\r'.
+- ImFont: added GetCharAdvance() helper. Exposed font Ascent and font Descent.
+- ImFont: additional rendering optimizations.
+- Metrics windows display storage size.
+
+
+-----------------------------------------------------------------------
+ VERSION 1.40 (2015-05-31)
+-----------------------------------------------------------------------
+
+Decorated log: https://github.com/ocornut/imgui/releases/tag/v1.40
+
+Breaking Changes:
+
+- The BeginPopup() API (introduced in 1.37) had to be changed to allow for stacked popups and menus.
+  Use OpenPopup() to toggle the opened state and BeginPopup() to append.**
+- The third parameter of Button(), 'repeat_if_held' has been removed. While it's been very rarely used,
+  some code will possibly break if you didn't rely on the default parameter.
+  Use PushButtonRepeat()/PopButtonRepeat() to configure repeat.
+- Renamed IsRectClipped() to !IsRectVisible() for consistency (opposite return value!). Kept inline redirection function (will obsolete)
+- Renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline indirection function (will obsolete).
+
+Other Changes:
+
+- Menus: Added a menu system! Menus are typically populated with menu items and sub-menus, but you can add any sort of
+  widgets in them (buttons, text inputs, sliders, etc.). (#126)
+- Menus: Added MenuItem() to append a menu item. Optional shortcut display, acts a button & toggle with checked/unchecked state,
+  disabled mode. Menu items can be used in any window.
+- Menus: Added BeginMenu() to append a sub-menu. Note that you generally want to add sub-menu inside a popup or a menu-bar.
+  They will work inside a normal window but it will be a bit unusual.
+- Menus: Added BeginMenuBar() to append to window menu-bar (set ImGuiWindowFlags_MenuBar to enable).
+- Menus: Added BeginMainMenuBar() helper to append to a fullscreen main menu-bar.
+- Popups: Support for stacked popups. Each popup level inhibit inputs to lower levels. The menus system is based on this. (#126).
+- Popups: Added BeginPopupContextItem(), BeginPopupContextWindow(), BeginPopupContextVoid() to create a popup window on mouse-click.
+- Popups: Popups have borders by default (#197), attenuated border alpha in default theme.
+- Popups & Tooltip: Fit within display. Handling various positioning/sizing/scrolling edge cases. Better hysteresis when moving
+  in corners. Tooltip always tries to stay away from mouse-cursor.
+- Added ImGuiStorage::GetVoidPtrRef() for manipulating stored void*.
+- Added IsKeyDown() IsMouseDown() as convenience and for consistency with existing functions (instead of reading them from IO structures).
+- Added Dummy() helper to advance layout by a given size. Unlike InvisibleButton() this doesn't catch any click.
+- Added configurable io.KeyRepeatDelay, io.KeyRepeatRate keyboard and mouse repeat rate.
+- Added PushButtonRepeat() / PopButtonRepeat() to enable hold-button-to-repeat press on any button.
+- Removed the third 'repeat' parameter of Button().
+- Added IsAnyItemHovered() helper.
+- Added GetItemsLineHeightWithSpacing() helper.
+- Added ImGuiListClipper helper for clipping large list of evenly sized items, to avoid using CalcListClipping() directly.
+- Separator: within group start on group horizontal offset. (#205)
+- InputText: Fixed incorrect edit state after text buffer is appended to by user via the callback. (#206)
+- InputText: CTRL+letter-key shortcuts (e.g. CTRL+C/V/X) makes sure only CTRL is pressed. (#214)
+- InputText: Fixed cursor generating a zero-width wire-frame rectangle turning into a division by zero (would go unnoticed
+  unless you trapped exceptions).
+- InputFloatN/InputIntN: Flags parameter added to match scalar versions. (#218)
+- Selectable: Horizontal filling not declared to ItemSize() so Selectable(),SameLine() works and we can better auto-fit the window.
+- Selectable: Handling text baseline alignment for line that aren't of text height.
+- Combo: Empty label doesn't add ItemInnerSpacing alignment, matching other widgets.
+- EndGroup: Carries the text base offset from the last line of the group (sort of incorrect but better than nothing,
+  should use the first line of the group, will implement in the future).
+- Columns: distinguish columns-set ID from other widgets as a convenience, added asserts and sailors.
+- ListBox: ListBox() function only use public API to encourage creating custom versions. ListBoxHeader() can return false.
+- ListBox: Uses ImGuiListClipper and assume items of matching height, so large lists can be handled.
+- Plot: overlay label clipped within frame when not fitting.
+- Window: Added ImGuiSetCond_Appearing to test the hidden->visible transition in SetWindow***/SetNextWindow*** functions.
+- Window: Auto-fitting cancel out one worth of vertical spacing for vertical symmetry (like what group and tooltip do).
+- Window: Default item width for auto-resizing windows expressed as a factor of font height, scales better with different font.
+- Window: Fixed auto-fit calculation mismatch of whether a scrollbar will be added by maximum height clamping. Also honor NoScrollBar in the case of height clamping, not adding extra horizontal space.
+- Window: Hovering require to hover same child window. Reverted 860cf57 (December 3). Might break something if you have
+  child overlapping items in parent window.
+- Window: Fixed appending multiple times to an existing child via multiple BeginChild/EndChild calls to same child name.
+  Allows a simple form of out-of-order appending.
+- Window: Fixed auto-filling child window using WindowMinSize at their minimum size, irrelevant.
+- Metrics: Added io.MetricsActiveWindows counter. (#213.
+- Metrics: Added io.MetricsAllocs counter (number of active memory allocations).
+- Metrics: ShowMetricsWindow() shows popups stack, allocations.
+- Style: Added style.DisplayWindowPadding to prevent windows from reaching edges of display (similar to style.DisplaySafeAreaPadding which is still in effect and also affect popups/tooltips).
+- Style: Removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same).
+- Style: Added style.ScrollbarRounding. (#212)
+- Style: Added ImGuiCol_TextDisabled for disabled text. Added TextDisabled() helper.
+- Style: Added style.WindowTitleAlign alignment options, to e.g. center title on windows. (#222)
+- ImVector: tweak growth strategy, matches vector from VS2010.
+- ImFontAtlas: Added ClearFonts(), making the different clear funcs more explicit. (#224)
+- ImFontAtlas: Fixed appending new fonts without clearing existing fonts. Clearing input data left to application. (#224)
+- ImDrawList: Merge draw command better, cases of multiple Begin/End gets merged properly.
+- Store common stacked settings contiguously in memory to avoid heap allocation for unused features, and reduce cache misses.
+- Shutdown() tests for g.IO.Fonts not being NULL to ease use of multiple ImGui contexts. (#207)
+- Added IMGUI_DISABLE_OBSOLETE_FUNCTIONS define to disable the functions that are meant to be removed.
+- Examples: Added ? marks with tooltips next to various widgets. Added more comments in the demo window.
+- Examples: Added Menu-bar example.
+- Examples: Added Simple Layout example.
+- Examples: AutoResize demo doesn't use TextWrapped().
+- Examples: Console example uses standard malloc/free, makes more sense as a copy & pastable example.
+- Examples: DirectX9/11: Fixed key mapping for down arrow.
+- Examples: DirectX9/11: hide OS cursor if ImGui is drawing it. (#155)
+- Examples: DirectX11: explicitly set rasterizer state.
+- Examples: OpenGL3: Add conditional compilation of forward compat as required by glfw on OSX. (#229)
+- Fixed build with Visual Studio 2008 (possibly earlier versions as well).
+- Other fixes, comments, tweaks.

 ### 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 state duplication, state synchronization and state storage 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 is typically very small. 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 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._

 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 and at ease with those concepts, it should take you less than an hour to integrate Dear ImGui in your custom engine, but 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!_

-<b>Where is the documentation?</b>
+**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.

 See the FAQ in imgui.cpp for answers.
 
-<b>How do you use Dear ImGui on a platform that may not have a mouse or keyboard?</b>
-
-You can control Dear ImGui with a gamepad, see the explanation in imgui.cpp about how to use the navigation feature (short version: map your gamepad inputs into the `io.NavInputs[]` array and set `io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad`).
-
-You can share your computer mouse seamlessly with your console/tablet/phone using [Synergy](http://synergy-project.org). This is the preferred solution for developer productivity. In particular, their [micro-synergy-client](https://github.com/symless/micro-synergy-client) repo there is _uSynergy.c_ sources for a small embeddable that you can use on any platform to connect to your host PC using Synergy 1.x. You may also use a third party solution such as [Remote ImGui](https://github.com/JordiRos/remoteimgui).
-
-For touch inputs, you can increase the hit box of widgets (via the _style.TouchPadding_ setting) to accommodate a little for the lack of precision of touch inputs, but it is recommended you use a mouse or gamepad to allow optimizing for screen real-estate and precision.
-
-<b>Can you create elaborate/serious tools with Dear ImGui?</b>
+**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.
 
-<b>Can you reskin the look of Dear ImGui?</b>
+**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):

-<b>Why using C++ (as opposed to C)?</b>
+**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 reasonably maintained [c-api for ImGui](https://github.com/Extrawurst/cimgui) by Stephan Dilly designed for binding in other languages. 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 imgui principles at [Q-Games](http://www.q-games.com) where Atman had dropped his own simple imgui 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.
