f0ab104f070bc7f569404826fea1828ed985638cvboxsync * Note: much of this is vestigial from mfb/cfb times. This should
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * really be simplified even further.
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * Machine dependent values:
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * GLYPHPADBYTES should be chosen with consideration for the space-time
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * trade-off. Padding to 0 bytes means that there is no wasted space
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * in the font bitmaps (both on disk and in memory), but that access of
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * the bitmaps will cause odd-address memory references. Padding to
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * 2 bytes would ensure even address memory references and would
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * be suitable for a 68010-class machine, but at the expense of wasted
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * space in the font bitmaps. Padding to 4 bytes would be good
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * for real 32 bit machines, etc. Be sure that you tell the font
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * compiler what kind of padding you want because its defines are
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * kept separate from this. See server/include/font.h for how
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * GLYPHPADBYTES is used.
