 - Fonts: 'float size_pixels' passed to AddFontXXX() functions is now rounded to lowest integer.
   This is because our layout/font system currently doesn't fully support non-integer sizes. Until
   it does, this has been a common pitfall leading to more or less subtle issues. (#3164, #3309, #6800)
