Draws a crosshatch from the Outside-In of a given color and
forms a given number of boxes in each direction. All lines are
one (1) pixel thick. The first and last lines in each direction are
at the very edges of active video. All the lines in a given direction
are spaced equally. Any remaining pixels are added to the boxes
along the horizontal and vertical centers of the image.
The FMTU command instructs the generator to use the new
setting. The ALLU command updates hardware to the new setting
and redraws the test image.
