b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * Note: much of this is vestigial from mfb/cfb times. This should
b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * really be simplified even further.
b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * Machine dependent values:
b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * GLYPHPADBYTES should be chosen with consideration for the space-time
b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * trade-off. Padding to 0 bytes means that there is no wasted space
b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * in the font bitmaps (both on disk and in memory), but that access of
b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * the bitmaps will cause odd-address memory references. Padding to
b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * 2 bytes would ensure even address memory references and would
b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * be suitable for a 68010-class machine, but at the expense of wasted
b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * space in the font bitmaps. Padding to 4 bytes would be good
b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * for real 32 bit machines, etc. Be sure that you tell the font
b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * compiler what kind of padding you want because its defines are
b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * kept separate from this. See server/include/font.h for how
b9a21c3c91c47e090316e28d759194e46628ed49vboxsync * GLYPHPADBYTES is used.
