- window: expose contents size. (#1045)
- window: GetWindowSize() returns (0,0) when not calculated? (#1045)
!- scrolling: allow immediately effective change of scroll after Begin() if we haven't appended items yet.
- scrolling/clipping: separator on the initial position of a window is not visible (cursorpos.y <= clippos.y)
- scrolling/clipping: separator on the initial position of a window is not visible (cursorpos.y <= clippos.y). (2017-08-20: can't repro)
- drawlist: move Font, FontSize, FontTexUvWhitePixel inside ImDrawList and make it self-contained (apart from drawing settings?)
- drawlist: make it easier to toggle AA per primitive, so we can use e.g. non-AA fill + AA borders more naturally

Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code.
Also read releases logs https://github.com/ocornut/imgui/releases for more details.
- 2016/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency.
- 2016/08/20 (1.51) - 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.
- 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame.
- 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow(), note that most uses relied on default parameters completely.
- 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely.
- 2017/08/13 (1.51) - renamed ImGuiCol_Columns_*** to ImGuiCol_Separator_***
- 2017/08/11 (1.51) - renamed ImGuiSetCond_*** types and flags to ImGuiCond_***. Kept redirection enums (will obsolete).
- 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton().
