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.

Renaming and massaging internal Settings/Ini functions (#923)

Fixed clicking on a window's void while staying still overzealously marking .ini settings as dirty (#923)

SliderInt, SliderFloat(): Fixed edge case where style.GrabMinSize being bigger than slider width can lead to a division by zero (#919)

SliderInt(): Fixed reverse direction mode when (v_max-v_min)==-1 (#854) (+ ref #919)

ImFileOpen: MinGW uses _wfopen() codepath to support UTF-8 filenames (#917)

SliderInt, SliderFloat() interacting enforce modifying to the value to be consistent with other widget behaviors (#919)

SliderInt, SliderFloat() Better display support for v_min==v_max range. (#919)

Split SliderBehaviorCalcRatioFromValue() out of SliderBehavior(), fix + Not using fabsf() anymore

Split SliderBehaviorCalcRatioFromValue() out from SliderBehavior()

SliderInt, SliderFloat: Passing v_min==v_max disable setting value from clicking/dragging (#919)

SliderInt, SliderFloat: Renaming

SliderInt, SliderFloat(): support reverse direction (#854)

Using _wfopen() under Windows+MSVC because fopen() doesn't support UTF-8 encoding. Wrapped as ImFileOpen(). (#917)

Tools: binary_to_compressed_c.cpp : comments + link to precompiled binaries
