#ifndef IMGUI_DISABLE
// Usage:
// - Add '#define IMGUI_ENABLE_FREETYPE' in your imconfig to enable support for imgui_freetype in imgui.
// - 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()
// Optional support for OpenType SVG fonts:
// - Add '#define IMGUI_ENABLE_FREETYPE_PLUTOSVG' to use plutosvg (not provided). See #7927.

// Hinting greatly impacts visuals (and glyph sizes).
// - By default, hinting is enabled and the font's native hinter is preferred over the auto-hinter.
// - When disabled, FreeType generates blurrier glyphs, more or less matches the stb_truetype.h
// - The Default hinting mode usually looks good, but may distort glyphs in an unusual way.
// - The Light hinting mode generates fuzzier glyphs but better matches Microsoft's rasterizer.
