* src/type1/t1load.c (parse_dict): Handle RD' and -|' commands
outside of /Subrs or /CharStrings. This can happen if there is additional code manipulating those two arrays so that FreeType doesn't recognize them properly. (T1_Open_Face): Improve an error message. Remove CR/LF on many files.

* 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.
|

<FTC_INLINE>: Provide macro version which doesn't use inline code.

<FTC_INLINE>: Ditto.

Use FTC_MRULIST_LOOKUP_CMP.

macro.

(FTC_MRULIST_LOOKUP): Use it.

|

* src/cache/Jamfile (_sources), src/cache/descrip.mms: Updated.

* src/cache/ftcbasic.c: Fix compiler warnings.

FTC_Manager_LookupFace) <FTC_INLINE>: Use FTC_MRULIST_LOOKUP_CMP.

* 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'.

|

/*
|
||||
*
|
||||
* 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.
