+ * 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
