46 * glyph caching code is responsible for actually creating the accelerated
47 * memory surface that will contain the individual glyph images.
49 * Each glyph contains a reference to a list of cell infos - one per glyph
50 * cache. There may be multiple glyph caches (for example, one per graphics
51 * adapter), so if the glyph is cached on two devices its cell list will
52 * consists of two elements corresponding to different glyph caches.
54 * The platform-specific glyph caching code is supposed to use
55 * GetCellInfoForCache method for retrieving cache infos from the glyph's list.
57 * Note that if it is guaranteed that there will be only one global glyph
59 * for retrieving cell info for the glyph, but instead just use the struct's
91 * Attempts to add the provided glyph to the specified cache. If the
93 * stored in the glyph's cellInfo field; otherwise, its cellInfo field is
94 * set to NULL, indicating that the glyph's original bits should be rendered
95 * instead. If the cache is full, the least-recently-used glyph is
96 * invalidated and its cache cell is reassigned to the new glyph being added.
99 * "virtual" glyph cache is available for the glyph image. Platform specific
100 * glyph caching code is responsible for actually caching the glyph image
104 * cache and glyph's cell lists, NULL otherwise.
