// Usage:
// - Add '#define IMGUI_ENABLE_FREETYPE' in your imconfig to automatically enable support
// for imgui_freetype in imgui. It is equivalent to selecting the default loader with:
// io.Fonts.FontLoader = ImGuiFreeType::GetFontLoader()
// io.Fonts->SetFontLoader(ImGuiFreeType::GetFontLoader())
// Optional support for OpenType SVG fonts:
// - Add '#define IMGUI_ENABLE_FREETYPE_PLUTOSVG' to use plutosvg (not provided). See #7927.
