// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2021/03/05: added ImGuiFreeTypeBuilderFlags_Bitmap to load bitmap glyphs.
// 2021/03/02: set 'atlas->TexPixelsUseColors = true' to help some backends with deciding of a prefered texture format.
// 2021/01/28: added support for color-layered glyphs via ImGuiFreeTypeBuilderFlags_LoadColor (require Freetype 2.10+).
// 2021/01/26: simplified integration by using '#define IMGUI_ENABLE_FREETYPE'.
// renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API. removed ImGuiFreeType::BuildFontAtlas().
