Other changes:
- ImDrawList: texture baked storage for thick line reduced from ~64x64 to ~32x32. (#3245)
- imgui_freetype: fixed issue where glyph advances would incorrectly be
snapped to pixels. Effectively it would only be noticeable when hinting
is disabled with ImGuiFreeTypeBuilderFlags_NoHinting, as hinting itself

one without the other is never correct. (#8174, #6556, #6336, #4723)
