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

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.
