f78b12e570284aa8291f4ca1add24937fd107403vboxsync * Note: much of this is vestigial from mfb/cfb times. This should
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * really be simplified even further.
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * Machine dependent values:
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * GLYPHPADBYTES should be chosen with consideration for the space-time
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * trade-off. Padding to 0 bytes means that there is no wasted space
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * in the font bitmaps (both on disk and in memory), but that access of
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * the bitmaps will cause odd-address memory references. Padding to
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * 2 bytes would ensure even address memory references and would
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * be suitable for a 68010-class machine, but at the expense of wasted
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * space in the font bitmaps. Padding to 4 bytes would be good
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * for real 32 bit machines, etc. Be sure that you tell the font
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * compiler what kind of padding you want because its defines are
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * kept separate from this. See server/include/font.h for how
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * GLYPHPADBYTES is used.
