e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * GLYPHPADBYTES should be chosen with consideration for the space-time
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * trade-off. Padding to 0 bytes means that there is no wasted space
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * in the font bitmaps (both on disk and in memory), but that access of
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * the bitmaps will cause odd-address memory references. Padding to
612ab06c3d17ed10137724a3745004d09566f53avboxsync * 2 bytes would ensure even address memory references and would
612ab06c3d17ed10137724a3745004d09566f53avboxsync * be suitable for a 68010-class machine, but at the expense of wasted
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * space in the font bitmaps. Padding to 4 bytes would be good
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * for real 32 bit machines, etc. Be sure that you tell the font
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * compiler what kind of padding you want because its defines are
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * kept separate from this. See server/include/font.h for how
e0e0c19eefceaf5d4ec40f9466b58a771f50e799vboxsync * GLYPHPADBYTES is used.
