Scrollbar: Comments. Fixed potential div-by-zero error which I can repro now, so added an assert to notify us if it's actually ever useful or not.

Added PushStyleColor(ImGuiCol idx, ImU32 col) overload. (Which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix.)

Marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame. Removed the broken __LINE__ from IMGUI_ONCE_UPON_A_FRAME

OpenPopupEx() internal tweaks to receive an ImGuiID, BeginPopupContextXXX shortening unnecessarily long identifier.

PushID()/PopID() to not need to mark parent window as Accessed (needlessly waking up the root "Debug" window) (#747)

(api breaking) changed parameter order for BeginPopupContextWindow(), note that most uses relied on default parameters completely.

Undo part of 32dbe83 to keep the same name for both overloads (#891, #799)

Moved TODO list to TODO.txt

Window size can be loaded from .ini data even if ImGuiWindowFlags_NoResize flag is set (#1048, #1056)

Style: Tweaked default border (which is off by default) to be less noticeable (#707, #1019)

Style: renamed ImGuiCol_Columns_*** to ImGuiCol_Separator_*** (BREAKING), Separator() uses this color as well. (#707, #1019)

PathArcToFast: Minor renaming for clarification. Comments.

Fonts: Adding references to the fact that .OTF fonts are supported (but haven't renamed the entry points)

Fix broken ImGuiColorEditFlags_NoAlpha flag check ...

* Fixes warning:
  imgui.cpp:9295:98: warning: enum constant in boolean context [-Wint-in-bool-context]

Fixed (unlikely) Ini saving crash if the ImGuiWindowFlags_NoSavedSettings gets removed from a window after its creation (#1000) + minor FAQ tweaks

RenderArrow(): fix warning. re-orderer lines to match enum order.

Documentation tweaks

Renamed ImGuiSetCond_XXX type and enums to ImGuiCond_XXX, kept old enums under #ifdef IMGUI_DISABLE_OBSOLETE_FUNCTIONS

ColorPicker: Fixes for when ImGuiColorEditFlags_NoOptions flag is set: always read a default picker type + forward flag to sub ColorEdit widgets. (#346)

Removed old ValueColor() helpers. (#346)

RenderCheckMark() tidying up

Added ImFontAtlas::GlyphRangesBuilder helper + doc

Comments, FAQ entry (#586, #1105)

Minor string typo

Comments

Added SetColorEditOptions(). ColorPicker4: context menu to select picker type and alpha bar. Reorganized flags (again!). (#346)
