/** * The FreetypeManager caches various aspects of Freetype fonts * * It mainly consists of two std::unordered_map lists, which hold the items of the cache. * * They form kind of a tree, with FreetypeFontFile as the roots, referenced by multiple FreetypeFontInfo * entries, which are referenced by the FreetypeFont items. * * All of these items have reference counters, but these don't control the items life-cycle, but that of * the managed resources. * * The respective resources are: * FreetypeFontFile = holds the mmapped font file, as long as it's used by any FreetypeFontInfo. * FreetypeFontInfo = holds the FT_FaceRec_ object, as long as it's used by any FreetypeFont. * FreetypeFont = holds the FT_SizeRec_ and is owned by a FreetypeFontInstance * * FreetypeFontInfo therefore is embedded in the Freetype subclass of PhysicalFontFace. * FreetypeFont is owned by FreetypeFontInstance, the Freetype subclass of LogicalFontInstance. * * Nowadays there is not really a reason to have separate files for the classes, as the FreetypeManager * is just about handling of Freetype based fonts, not some abstract glyphs.
