because the A2024 is actually a "greyscale" monitor rather than a pure
"black & white" monitor. You can display > 32 shades of grey with it so
2 bitplanes makes sense. One way to use two bitplanes is to set the 
two intermediate colors to 33% grey and 66% grey. Then pretend you have
a 2016 X 1600 screen and use the other colors for antialiasing.
