61cb83a8ccd1dd7f671f31fa93c9d8b7be09b4ccvboxsync * Note: much of this is vestigial from mfb/cfb times. This should
61cb83a8ccd1dd7f671f31fa93c9d8b7be09b4ccvboxsync * really be simplified even further.
61cb83a8ccd1dd7f671f31fa93c9d8b7be09b4ccvboxsync * Machine dependent values:
61cb83a8ccd1dd7f671f31fa93c9d8b7be09b4ccvboxsync * GLYPHPADBYTES should be chosen with consideration for the space-time
61cb83a8ccd1dd7f671f31fa93c9d8b7be09b4ccvboxsync * trade-off. Padding to 0 bytes means that there is no wasted space
61cb83a8ccd1dd7f671f31fa93c9d8b7be09b4ccvboxsync * in the font bitmaps (both on disk and in memory), but that access of
61cb83a8ccd1dd7f671f31fa93c9d8b7be09b4ccvboxsync * the bitmaps will cause odd-address memory references. Padding to
61cb83a8ccd1dd7f671f31fa93c9d8b7be09b4ccvboxsync * 2 bytes would ensure even address memory references and would
61cb83a8ccd1dd7f671f31fa93c9d8b7be09b4ccvboxsync * be suitable for a 68010-class machine, but at the expense of wasted
61cb83a8ccd1dd7f671f31fa93c9d8b7be09b4ccvboxsync * space in the font bitmaps. Padding to 4 bytes would be good
61cb83a8ccd1dd7f671f31fa93c9d8b7be09b4ccvboxsync * for real 32 bit machines, etc. Be sure that you tell the font
61cb83a8ccd1dd7f671f31fa93c9d8b7be09b4ccvboxsync * compiler what kind of padding you want because its defines are
61cb83a8ccd1dd7f671f31fa93c9d8b7be09b4ccvboxsync * kept separate from this. See server/include/font.h for how
61cb83a8ccd1dd7f671f31fa93c9d8b7be09b4ccvboxsync * GLYPHPADBYTES is used.
