ImDrawList: Added GetClipRectMin(), GetClipRectMax() helpers. Comments.

Columns: Fixed offset rounding leading to SetColumnOffset() being destructive when ImGuiColumnsFlags_NoPreserveWidths flag is not set. (#913, #125)

Columns: Moved BeginColumns/EndColumns/flags from #913 to imgui_internals.h + minor shallow tweaks. Removed demo code temporarily. (#125)

Merge branch 'master' of https://github.com/ggtucker/imgui into ggtucker-master ...

Renamed GetStyleColName() to GetStyleColorName() for consistency. Extra comments in Api Breaking Changes section.

Added GetStyleColorVec4()

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.)

ImFontAtlas: Draft of an api to submit custom rectangle (not exposed). Atlas default texture chunk using it. (WIP: we are still storing mouse UV outside in GImGui)

ImVector: Added a const

added missing IMGUI_API to ImGuiTextFilter methods implemented in imgui.cpp

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.

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

Revert d2c219d #826 + tidying up ImFont::RenderChar()

Merge pull request #826 from swetland/patch ...

ImFont: add RenderGlyph() to allow rendering of individual glyphs post-query

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

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

Documentation tweaks

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

Removed old ValueColor() helpers. (#346)

Added ImFontAtlas::GlyphRangesBuilder helper + doc

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

Moved ColorEdit, ColorPicker declaration in their own section of imgui.h, minor comments adjustment (#346)

ColorPicker: Hue wheel + SV triangle picker mode (mode selection flags still wip, missing context menu and persistent options). (#346)

Renamed ImGuiColorEditFlags_ModeMask_ to ImGuiColorEditFlags_InputsModeMask_ (#346)

ColorEdit4: Preliminary support for ImGuiColorEditFlags_HDR flag (currently only lift limits). (#346)
