/*
*
* FTC_GCache is an _abstract_ cache object optimized to store glyph
* data. It works as follows:
*
* - It manages FTC_GNode objects. Each one of them can hold one or more
* glyph `items'. Item types are not specified in the FTC_GCache but
* in classes that extend it.
*
* - Glyph attributes, like face ID, character size, render mode, etc.,
* can be grouped into abstract `glyph families'. This avoids storing
* the attributes within the FTC_GCache, since it is likely that many
* FTC_GNodes will belong to the same family in typical uses.
*
* - Each FTC_GNode is thus an FTC_Node with two additional fields:
*
* * gindex: A glyph index, or the first index in a glyph range.
* * family: A pointer to a glyph `family'.
*
* - Family types are not fully specific in the FTC_Family type, but
* by classes that extend it.
*
* Note that both FTC_ImageCache and FTC_SBitCache extend FTC_GCache.
* They share an FTC_Family sub-class called FTC_BasicFamily which is
* used to store the following data: face ID, pixel/point sizes, load
* flags. For more details see the file `src/cache/ftcbasic.c'.
*
* Client applications can extend FTC_GNode with their own FTC_GNode
* and FTC_Family sub-classes to implement more complex caches (e.g.,
* handling automatic synthesis, like obliquing & emboldening, colored
* glyphs, etc.).
*
* See also the FTC_ICache & FTC_SCache classes in `ftcimage.h' and
* `ftcsbits.h', which both extend FTC_GCache with additional
* optimizations.
*
* A typical FTC_GCache implementation must provide at least the
* following:
*
* - FTC_GNode sub-class, e.g. MyNode, with relevant methods:
* my_node_new (must call FTC_GNode_Init)
* my_node_free (must call FTC_GNode_Done)
* my_node_compare (must call FTC_GNode_Compare)
* my_node_remove_faceid (must call ftc_gnode_unselect in case
* of match)
*
* - FTC_Family sub-class, e.g. MyFamily, with relevant methods:
* my_family_compare
* my_family_init
* my_family_reset (optional)
* my_family_done
*
* - FTC_GQuery sub-class, e.g. MyQuery, to hold cache-specific query
* data.
*
* - Constant structures for a FTC_GNodeClass.
*
* - MyCacheNew() can be implemented easily as a call to the convenience
* function FTC_GCache_New.
*
* - MyCacheLookup with a call to FTC_GCache_Lookup. This function will
* automatically:
*
* - Search for the corresponding family in the cache, or create
* a new one if necessary. Put it in FTC_GQUERY(myquery).family
*
* - Call FTC_Cache_Lookup.
*
* If it returns NULL, you should create a new node, then call
* ftc_cache_add as usual.

/* A cache manager is in charge of the following: */
/* */
/* - Maintain a mapping between generic FTC_FaceIDs and live FT_Face */
/* objects. The mapping itself is performed through a user-provided */
/* callback. However, the manager maintains a small cache of FT_Face */
/* and FT_Size objects in order to speed up things considerably. */
/* */
/* - Manage one or more cache objects. Each cache is in charge of */
/* holding a varying number of `cache nodes'. Each cache node */
/* represents a minimal amount of individually accessible cached */
/* data. For example, a cache node can be an FT_Glyph image */
/* containing a vector outline, or some glyph metrics, or anything */
/* else. */
/* */
/* Each cache node has a certain size in bytes that is added to the */
/* total amount of `cache memory' within the manager. */
/* */
/* All cache nodes are located in a global LRU list, where the oldest */
/* node is at the tail of the list. */
/* */
/* Each node belongs to a single cache, and includes a reference */
/* count to avoid destroying it (due to caching). */
