 Other Changes:
 
 - ArrowButton: Fixed to honor PushButtonRepeat() setting (and internals' ImGuiItemFlags_ButtonRepeat).
 - ArrowButton: Setup current line text baseline so that ArrowButton() + SameLine() + Text() are aligned properly.

+  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.
