Remove trailing spaces (grep for ' \r?$' in visual studio)

ImDrawList: clarified the name of many parameters so reading the code is a little easier. (#2740)

Version 1.73 WIP

Version 1.72b (patch for nav)

Version 1.73 WIP

Version 1.72

ImDrawList: Using ImDrawCornerFlags instead of int in various apis. ...

Demo: Using ImGuiColorEditrFlags instead of int.

Renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Keep redirection typedef (will obsolete).

Internals: ImGuiListClipper using absolute coordinate (instead of relative one). Minor no-op tweaks + ImDrawListSplitter assert

Style: Attenuated default opacity of ImGuiCol_Separator in Classic and Light styles.

Word-wrapping: Fixed overzealous word-wrapping when glyph edge lands exactly on the limit. Because of this, auto-fitting exactly unwrapped text would make it wrap. (fixes initial 1.15 commit, 78645a7d).

Disable -Wpragmas warning in GCC to avoid relying on version checks, as unusual/forks/mods don't appear to always have same warning<>version. (#2618) ...

+ Fix version number in imgui.h

ImDrawList: Fixed CloneOutput() helper crashing. Also removed unnecessary risk from ImDrawList::Clear(), draw lists are being clear before use each frame anyway. (#1860)

ImDrawList::ChannelsSplit(), ImDrawListSlitter: Fixed an issue with merging draw commands between channels 0 and 1. (#2624) Introduced by cef88f6.

Version 1.72 WIP

Version 1.71 + comments

Readme, comments, dear imgui prefixes

ImDrawListSplitter: Don't merge draw commands when crossing a VtxOffset boundary + Renamed fields ImDrawChannels to consistently suggest those are internal structures.

ImDrawListSplitter: Fix idx offset when merging (cef88f6) (#2591)

Internals: Added drawlist and color arg to RenderArrow(), RenderBullet(). Reordered args for RenderPixelEllipsis.

ImDrawListSplitter: Support merging consecutive draw commands straddling two channels. Support zero-init.

ImDrawListSplitter: extracted out of ImDrawList. Down the line we may obsolete the ImDrawList functions and encourage users to store the splitter aside, in the meanwhile ImDrawList holds a splitter. ...

(This will allow columns/table to recurse.)

ImDrawList: Fix broken channel splitting (another issue when the first channel is empty) (#2591) + fixed warnings with newer VS

Include <alloca.h> also when __SWITCH__ is defined (#2595) ...

Fixes compilation with devkitPro for Nintendo Switch

ImDrawList: Fix broken channel splitting (broken by d1e8b69) (#2591)

ImDrawList: Added ImDrawCmd::VtxOffset value to support large meshes (64k+ vertices) using 16-bits indices. To enable the feature, the renderer back-end needs to set 'io.BackendFlags |= ImGuiBackendFlags_HasVtxOffset' and honor the ImDrawCmd::VtxOffset field. Otherwise the value will always be zero. This has the advantage of preserving smaller index buffers and allowing to execute on hardware that do not support 32-bits indices. ...

ImDrawList: Added ImDrawCmd::IdxOffset value, equivalent to summing element count for each draw command. This is provided for convenience and consistency with VtxOffset. (#2591)

ImDrawList: Store initial flags for the frame in ImDrawListSharedData, reducing code duplication in setting up the flags.

ImFontGlyphRangesBuilder: Fixed unnecessarily over-sized buffer, which incidentally was also not fully cleared. Fixed edge case overflow when adding character 0xFFFF. (#2568)

Fixed GCC mem-access warnings (#2565) ...

+ using "if defined" more consistently for Clang.

Fix undefined behavior (#2561)
