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)

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

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

Comments about child menu positioning (#1086)

Fix ColorButton showing wrong hex value for alpha

Internal: Renamed ImLoadFileToMemory to ImFileLoadToMemory to be consistent with ImFileOpen + fix mismatching .h name (#917)

Added an explicit (internal) ClearActiveID() helper and removed the default NULL window parameter to internal SetActiveID(),

Combo, ListBox: Extra const correctness.

Minor documentation tweaks

const correctness for Combo and ListBox ...

Since Combo and ListBox only read and display the list of items, they
should not modify the pointers inside the array of pointers passed in.
Adding "const" here makes it possible to call these functions with such
an array of const pointers. Previously, a cast to "const char**" was
required as a workaround, otherwise there was a compile error.
