65fea56f17cd614bc8908264df980a62e1931468vboxsync * Note: much of this is vestigial from mfb/cfb times. This should
65fea56f17cd614bc8908264df980a62e1931468vboxsync * really be simplified even further.
65fea56f17cd614bc8908264df980a62e1931468vboxsync * Machine dependent values:
65fea56f17cd614bc8908264df980a62e1931468vboxsync * GLYPHPADBYTES should be chosen with consideration for the space-time
65fea56f17cd614bc8908264df980a62e1931468vboxsync * trade-off. Padding to 0 bytes means that there is no wasted space
65fea56f17cd614bc8908264df980a62e1931468vboxsync * in the font bitmaps (both on disk and in memory), but that access of
65fea56f17cd614bc8908264df980a62e1931468vboxsync * the bitmaps will cause odd-address memory references. Padding to
65fea56f17cd614bc8908264df980a62e1931468vboxsync * 2 bytes would ensure even address memory references and would
65fea56f17cd614bc8908264df980a62e1931468vboxsync * be suitable for a 68010-class machine, but at the expense of wasted
65fea56f17cd614bc8908264df980a62e1931468vboxsync * space in the font bitmaps. Padding to 4 bytes would be good
65fea56f17cd614bc8908264df980a62e1931468vboxsync * for real 32 bit machines, etc. Be sure that you tell the font
65fea56f17cd614bc8908264df980a62e1931468vboxsync * compiler what kind of padding you want because its defines are
65fea56f17cd614bc8908264df980a62e1931468vboxsync * kept separate from this. See server/include/font.h for how
65fea56f17cd614bc8908264df980a62e1931468vboxsync * GLYPHPADBYTES is used.
