- Fonts: (users of imgui_freetype): renamed ImFontAtlas::FontBuilderFlags to ImFontAtlas::FontLoaderFlags. Renamed ImFontConfig::FontBuilderFlags to ImFontConfig::FontLoaderFlags. Renamed ImGuiFreeTypeBuilderFlags to ImGuiFreeTypeLoaderFlags.
If you used runtime imgui_freetype selection rather than the default IMGUI_ENABLE_FREETYPE compile-time option: Renamed/reworked ImFontBuilderIO into ImFontLoader. Renamed ImGuiFreeType::GetBuilderForFreeType() to ImGuiFreeType::GetFontLoader().
- old: io.Fonts->FontBuilderIO = ImGuiFreeType::GetBuilderForFreeType()
- new: io.Fonts.FontLoader = ImGuiFreeType::GetFontLoader()
- new: io.Fonts->FontLoader = ImGuiFreeType::GetFontLoader()
- new: io.Fonts->SetFontLoader(ImGuiFreeType::GetFontLoader()) to change dynamically at runtime [from 1.92.1]
- Fonts: (users of custom rectangles, see #8466): Renamed AddCustomRectRegular() to AddCustomRect(). Added GetCustomRect() as a replacement for GetCustomRectByIndex() + CalcCustomRectUV().
- The output type of GetCustomRect() is now ImFontAtlasRect, which include UV coordinates. X->x, Y->y, Width->w, Height->h.
