// - v0.53: (2017/10/22) minor inconsequential change to match change in master (removed an unnecessary statement)
// - v0.54: (2018/01/22) fix for addition of ImFontAtlas::TexUvscale member
// - v0.55: (2018/02/04) moved to main imgui repository (away from http://www.github.com/ocornut/imgui_club)
// - v0.56: (2018/06/08) added support for ImFontConfig::GlyphMinAdvanceX, GlyphMaxAdvanceX
// Gamma Correct Blending:
// FreeType assumes blending in linear space rather than gamma space.
