+ * trade-off.  Padding to 0 bytes means that there is no wasted space

+ * in the font bitmaps (both on disk and in memory), but that access of

+ * the bitmaps will cause odd-address memory references.  Padding to

+ * 2 bytes would ensure even address memory references and would

+ * be suitable for a 68010-class machine, but at the expense of wasted

+ * space in the font bitmaps.  Padding to 4 bytes would be good

+ * for real 32 bit machines, etc.  Be sure that you tell the font

+ * compiler what kind of padding you want because its defines are

+ * kept separate from this.  See server/include/font.h for how

+ * GLYPHPADBYTES is used.
