draw a centered GRID
Custom image primitive
GRID <color> <number of horizontal boxes> <number of
vertical boxes>
<color> = available colors
<number of horizontal boxes> = half of number of pixels
<number of vertical boxes> = half of number of lines
None
Draws a crosshatch of a given color and forms a given number
of boxes in each direction. All lines are one (1) pixel thick. All
of the lines, in a given direction, are equally spaced. Any
remaining pixels are distributed as equally as possible around
the perimeter of the grid. This may cause the first and last lines
in each direction not to be at the very edges of video.
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.

Custom image primitive
GRIH <color> <number of pixels in line> < number of pixels
in space>
<color> = available colors
<number of pixels in line> = number of pixels
< number of pixels in space> = number of pixels
None
Draws equally spaced horizontal lines that form a grill over the
entire active video area. The primitive uses three (3) parameters.
The first is the color of the lines. The second is the thickness of
the lines and the third is the thickness of the space between the
lines.
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.
