- * This file describes the Server Natural Font format.
- * SNF fonts are both CPU-dependent and frame buffer bit order dependent.
- * This file is used by:
- * 1) the server, to hold font information read out of font files.
- * 2) font converters
- *
- * Each font file contains the following
- * data structures, with no padding in-between.
- *
- * 1) The XFONTINFO structure
- * hand-padded to a two-short boundary.
- * maxbounds.byteoffset is the total number of bytes in the
- * glpyh array
- * maxbounds.bitOffset is thetotal width of the unpadded font
- *
- * 2) The XCHARINFO array
- * indexed directly with character codes, both on disk
- * and in memory.
- *
- * 3) Character glyphs
- * padded in the server-natural way, and
- * ordered in the device-natural way.
- * End of glyphs padded to 32-bit boundary.
- *
- * 4) nProps font properties
- *
- * 5) a sequence of null-terminated strings, for font properties
