Readme, comments, dear imgui prefixes

ImDrawCallback: Allow to override the signature of ImDrawCallback by #define-ing it. This is meant to facilitate custom rendering back-ends passing local render-specific data to the draw callback.

Revert "Changed syntax for (very rarely used) IMGUI_OVERRIDE_DRAWVERT_STRUCT_LAYOUT mechanism, instead you only need to '#define ImDrawVert MyDrawVert' to use this feature, avoiding the need to declare the entire structure within an awkward macro. Using the old macro will now error with a message pointing you to the new method. (#38, #103, #1172, #1231, #2489)" ...

This reverts commit 597c024.

Changed syntax for (very rarely used) IMGUI_OVERRIDE_DRAWVERT_STRUCT_LAYOUT mechanism, instead you only need to '#define ImDrawVert MyDrawVert' to use this feature, avoiding the need to declare the entire structure within an awkward macro. Using the old macro will now error with a message pointing you to the new method. (#38, #103, #1172, #1231, #2489)

Renamed ImGuiBackendFlags_HasVtxOffset to ImGuiBackendFlags_RendererHasVtxOffset to match naming convention already used in viewport/docking branch. (#2591) + Fix OpenGL3 code missing flag.

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)

Update changelog, comments, made empty/no-text clipboard return NULL as with other implementation. Minor style tweaks. (#2546) ...

Fixed IMGUI_DISABLE_WIN32_FUNCTIONS not disabling IME code.

Config: Added IMGUI_DISABLE_WIN32_FUNCTIONS to disable linking with _any_ Win32 function, as a general forward compatible measure.

FAQ update

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

Remove trailing white spaces.

Added ImAtof, ImCeil, ImFloorStd to IMGUI_DISABLE_MATH_FUNCTIONS for consistency. Configuration comments.

Added IMGUI_DISABLE_MATH_FUNCTIONS in imconfig.h to make it slightly easier to redefine wrappers to std maths functions such as fabsf(), fmodf(), etc. Comments.

InputText: tweaks, minor refactoring, renaming + comments (#1695)

Comments (#1695)

imconfig: Added IMGUI_STB_TRUETYPE_FILENAME, IMGUI_STB_RECT_PACK_FILENAME + documenting IMGUI_DISABLE_STB_XXX flags and hiding IMGUI_STB_NAMESPACE which is misleading. ...

Fixed typos in todo list.

imgui.h: Various comments and tweaks.

Added IMGUI_USER_CONFIG to define a custom configuration filename. (#255, #1573, #1144, #41)

imconfig.h comments

Renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete).

Renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency. (ref #238, #520, #738)

Added IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS support in imconfig.h (#1038)

Renamed IsItemHoveredRect() to IsItemRectHovered(). Renamed IsMouseHoveringWindow() to IsWindowRectHovered() - follow up to previous commit 6be7d49 merged from Nav.

Comments about IMGUI_DISABLE_TEST_WINDOWS (#1240, #169)

imconfig: Added comment about redefining ImDrawIdx

Introduce IMGUI_USE_BGRA_PACKED_COLOR in imconfig.h. ...

When IMGUI_USE_BGRA_PACKED_COLOR is defined packed color hold in ImU32 use BGRA format instead RGBA.

imconfig.h tweak, not advertising IMGUI_INCLUDE_IMGUI_USER_INL anymore.
