Version 1.65

Renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h. (#1718, #2036) ...

If you were conveniently using the imgui copy of those STB headers in your project, you will have to update your include paths.
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.

Refactor: Tweaked and improved the sectioning to facilitate grepping/moving around and applied to all files. (#2036)

Version 1.65 WIP

Version 1.64

Tweak comments and indexes

Refactor: Moved Scrollbar function from imgui.cpp to imgui_widgets.cpp, added file index (#2036)

Version 1.64 WIP

Version 1.63

Internals: Tidying up, moving helpers to imgui_internal.h (in prevision of 1.64 refactor)

ImFontAtlas Comments (#2042) + added ImGuiFontAtlas_None for consistency.

ImDrawList: Large text passed to AddText() are being scanned for their end in order to avoid pre-reserving too many vertices.

ImDrawList: Fixed clipping of leading lines above the clipping rectangle from counting in the worst case vertices reservation. (fix code added in #200!)

Internals: Extracted RenderMouseCursor() out of EndFrame(). Moved to imgui_draw.cpp along with RenderArrowPointingAt(). Comments. (#2013)

Internals: Changed signature of ShadeVerts functions to remove pointers. (#1286, #1700, #1986)

ImFontAtlas::AddFontDefault: Made it possible to override glyph ranges. (#1965)

Internals: Drag and Drop: default drop preview use a narrower clipping rectangle (no effect here, but other branches uses a narrow clipping rectangle that was too small so this is a fix for it) + Comments

Added asserts to catch illegal modifications of the font atlas between NewFrame() and EndFrame()/Render(). (#1958)

Fix warning when IMGUI_DEFINE_MATH_OPERATORS is already defined by build system. (#1950)

Comments, exposed a few things in imgui_internal.h for consistency, added ImQsort wrapper.

Revert part of c7016c2 incorrectly renaming ImGuiCol_NavWindowingHighlight to ImGuiCol_NavWindowListHighlight, that was wholly unnecessary (and not documented!). (also invalidate #1939)

Nav: Added a CTRL+TAB window list and changed the highlight system accordingly. (#787)

Internals: Removed unused ShadeVertsLinearAlphaGradientForLeftToRightText code.

Fixed a include build issue for Cygwin in non-POSIX (Win32) mode. (#1917, #1319, #276)

Tweaked software mouse cursor offset to match the offset of the corresponding Windows 10 cursors. (followup to #1914)

Fixed software Hand cursor from not actually working. Fixed demo from crashing. Fixed typo and extraneous trailing space. Added Changelogs. (#1913, #1914)

add hand cursor support (+11 squashed commit)

Version 1.63 WIP

Demo: Fixed incorrect response to Begin() returning false in overlay demo (which cannot happen since we don't have a title bar, but that doesn't make it a good behaving demo!).
