If you have a pixmap that is 1 bit deep and copy it to another
pixmap which is half the size and several bits deep will color
copybits average groups of four pixels in the source image to produce
one of four grey scales in the destination? Here's an example
with a 2x2 source array:
Source = 1 1
0 1
copied to a 1x1 pixmap will you get a black pixel or a 75% grey
one?
