/*************************************************************************/
/* */
/* A small technical note regarding automatic hinting in order to */
/* clarify this module interface. */
/* */
/* An automatic hinter might compute two kinds of data for a given face: */
/* */
/* - global hints: Usually some metrics that describe global properties */
/* of the face. It is computed by scanning more or less */
/* aggressively the glyphs in the face, and thus can be */
/* very slow to compute (even if the size of global */
/* hints is really small). */
/* */
/* - glyph hints: These describe some important features of the glyph */
/* outline, as well as how to align them. They are */
/* generally much faster to compute than global hints. */
/* */
/* The current FreeType auto-hinter does a pretty good job while */
/* performing fast computations for both global and glyph hints. */
/* However, we might be interested in introducing more complex and */
/* powerful algorithms in the future, like the one described in the John */
/* D. Hobby paper, which unfortunately requires a lot more horsepower. */
/* */
/* Because a sufficiently sophisticated font management system would */
/* typically implement an LRU cache of opened face objects to reduce */
/* memory usage, it is a good idea to be able to avoid recomputing */
/* global hints every time the same face is re-opened. */
/* */
/* We thus provide the ability to cache global hints outside of the face */
/* object, in order to speed up font re-opening time. Of course, this */
/* feature is purely optional, so most client programs won't even notice */
/* it. */
/* */
/* I initially thought that it would be a good idea to cache the glyph */
/* hints too. However, my general idea now is that if you really need */
/* to cache these too, you are simply in need of a new font format, */
/* where all this information could be stored within the font file and */
/* decoded on the fly. */

/* When FT_CONFIG_OPTION_PIC is defined a `create' function needs to */

/* it is no longer needed, a `destroy' function needs to be called to */
/* release that allocation. */
/* */
/* These functions should be manually called from the `pic_init' and */
/* `pic_free' functions of your module (see FT_DEFINE_MODULE). */
/* */
/* When FT_CONFIG_OPTION_PIC is not defined the array will be */
/* allocated in the global scope (or the scope where the macro is */
/* used). */

/*
* These types are used to support a `BDF ' table that isn't part of the
* official TrueType specification. It is mainly used in SFNT-based
* bitmap fonts that were generated from a set of BDF fonts.
*
* The format of the table is as follows.
*
* USHORT version `BDF ' table version number, should be 0x0001.
* USHORT strikeCount Number of strikes (bitmap sizes) in this table.
* ULONG stringTable Offset (from start of BDF table) to string
* table.
*
* This is followed by an array of `strikeCount' descriptors, having the
* following format.
*
* USHORT ppem Vertical pixels per EM for this strike.
* USHORT numItems Number of items for this strike (properties and
* atoms). Maximum is 255.
*
* This array in turn is followed by `strikeCount' value sets. Each
* `value set' is an array of `numItems' items with the following format.
*
* ULONG item_name Offset in string table to item name.
* USHORT item_type The item type. Possible values are
* 0 => string (e.g., COMMENT)
* 1 => atom (e.g., FONT or even SIZE)
* 2 => int32
* 3 => uint32
* 0x10 => A flag to indicate a properties. This
* is ORed with the above values.
* ULONG item_value For strings => Offset into string table without
* the corresponding double quotes.
* For atoms => Offset into string table.
* For integers => Direct value.
*
* All strings in the string table consist of bytes and are
* zero-terminated.
