/*******************************************************************
*
* ftxwidth.h
*
* Glyph Widths (and Heights) fast retrieval extension.

*
*
* This extension is used to parse the `glyf' table of a TrueType
* file in order to extract the bounding box of a given range of glyphs.
*
* The bounding box is then used to build font unit widths and heights
* that are returned in two parallel arrays.
*
* This extension is needed by the FreeType/2 OS/2 Font Driver.
