cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * Note: much of this is vestigial from mfb/cfb times. This should
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * really be simplified even further.
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * Machine dependent values:
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * GLYPHPADBYTES should be chosen with consideration for the space-time
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * trade-off. Padding to 0 bytes means that there is no wasted space
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * in the font bitmaps (both on disk and in memory), but that access of
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * the bitmaps will cause odd-address memory references. Padding to
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * 2 bytes would ensure even address memory references and would
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * be suitable for a 68010-class machine, but at the expense of wasted
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * space in the font bitmaps. Padding to 4 bytes would be good
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * for real 32 bit machines, etc. Be sure that you tell the font
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * compiler what kind of padding you want because its defines are
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * kept separate from this. See server/include/font.h for how
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * GLYPHPADBYTES is used.
