* src/sfnt/Jamfile: removing "ttcmap" from the list of sources 

* src/cache/*, include/freetype/cache/*: fixing a bug after heavy
        testing. The current sources are now "release candidates" for the
        final version of the cache sub-system

        * Jamfile: updating "refdoc" target, and adding "autohint" to the
        list of modules to build. Both the autohinter and autofitter will be
        built by default. But which one will be used is determined by
        the content of "ftmodule.h"

        * src/autofit/*: much updates, but the code is still buggy as hell.
        Aargh..

/*
*
* 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.

/*
*
* 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.
