/* 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 */
/* agressively 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 */
