Fixed Y scroll aiming when Horizontal Scrollbar is enabled (#665). Tweak log demo.

Fixes for Vertical Scrollbar not automatically getting enabled if enabled Horizontal Scrollbar straddle the vertical limit. (#1271, #246)

Fixed GetScrollMaxX(), GetScrollMaxY(). Tweak demo to display more data. Using functions in Begin(). (#1271)

Popups window can be moved (if they don't have explicit positions provided by user, or e.g. sub-menu popup) (#1252)

Comments, clarification about io.WantCaptureMouse, io.WantCaptureKeyboard flags timing and NewFrame(). (#1262)

Clipboard: [windows] Fixed not closing win32 clipboard on early return. (#1264)

DataTypeApplyOpFromText: renamed local variables + comments to avoid confusion about the fact that int and float paths are not totally symetrical. (#671)

Tooltip: SetTooltip() is expanded immediately into a window, honoring current font / styling setting. Add internal mechanism to override tooltips (not exposed in BeginTooltip yet because bools are evil) (#862)

Internals: Move GetVisibleRect() a few functions above so it gets to hang out with its peers.

Internals: renaming IndexWithinParent to OrderWithinParent

Removed IsPosHoveringAnyWindow() which was severaly broken and misleading (most people want to use io.WantCaptureMouse). Added dummy function with assert for now. (#1237)

Comments about GlyphExtraSpacing (#1192)

Fixed Clang unknown-warning-ignored warning by ignoring it..... we are truly living in a special time (#1090)

Comments (#383, #1224)

Comments about ImGuiStyleVar enum (#1198)

Revert 978c84d because int32 >> 32 tends to warns on some compilers/settings. Add ImU64 type. (#1184)

Removed dependency on int64_t type (unvailable in VS2008) by rewording an assert (#1184)

Further clarifications of the key indices passed to IsKeyXXX functions (#1159)

ImFontConfig: Removed MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset. (Breaking change)

Scrollbar: Avoid rendering when sizes are negative to reduce glitches (not sure how this ever slipped through - perhaps because of WindowMinSize settings).

Ignoring unreasonnable Clang -wformat-pedantic warning (#1090) ...

See e.g.
http://clang-developers.42468.n3.nabble.com/The-p-conversion-and-cast-to-void-td4044226.html

Renamed ImDrawList::PathFill() to ImDrawList::PathFillConvex() for clarity. (breaking API)

End() avoid calling Columns() if no columns set is open, not sure what it wasn't the case. ...

Pros: Faster. Avoid early crashes StackId underflow that are meant to be more gracefully caught by CheckStacksSize() (with more explicit assert). Cons: Excercise less code.

Clarified asserts in CheckStacksSize() when there is a stack mismatch
