-  /*
-   *
-   *  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.

-       *  Here, we want to load a small bitmap on-demand; we thus
-       *  need to call the `ftc_snode_load' function which may return
-       *  a non-zero error code only when we are out of memory (OOM).
-       *
-       *  The correct thing to do is to use @FTC_CACHE_TRYLOOP and
-       *  @FTC_CACHE_TRYLOOP_END in order to implement a retry loop
-       *  that is capable of flushing the cache incrementally when
-       *  an OOM errors occur.
-       *
-       *  However, we need to `lock' the node before this operation to
-       *  prevent it from being flushed within the loop.
-       *
-       *  When we exit the loop, we unlock the node, then check the `error'
-       *  variable.  If it is non-zero, this means that the cache was
-       *  completely flushed and that no usable memory was found to load
-       *  the bitmap.
-       *
-       *  We then prefer to return a value of 0 (i.e., NO MATCH).  This
-       *  ensures that the caller will try to allocate a new node.
-       *  This operation consequently _fail_ and the lookup function
-       *  returns the appropriate OOM error code.
-       *
-       *  Note that `buffer == NULL && width == 255' is a hack used to
-       *  tag `unavailable' bitmaps in the array.  We should never try
-       *  to load these.
