 In write mode 3, set/reset is automatically enabled for all four planes
 (the Enable Set/Reset register is ignored). The CPU data byte is rotated
 and then ANDed with the contents of the Bit Mask register, and the
 result of this operation is used as the contents of the Bit Mask
 register alone would normally be used. (If this is Greek to you, have a

 write mode 3 is excellent for a surprisingly large number of purposes,
 because it makes it possible to avoid the bane of VGA performance,
 **OUT**s. Some uses for write mode 3 include lines, circles, and solid
 and two-color pattern fills. Most importantly, write mode 3 is ideal for
 transparent text; that is, it makes it possible to draw text in 16-color
 graphics mode quickly without wiping out the background in the process.
