Trouble drawing point-sampled polygons

[James P. Loan]

Thanks for the replies to my problem. As Andrew Myers pointed out,
the trouble was with a bad ortho call. I outsmarted myself when
subtracting 1's and adding 0.5's between getsize(), viewport(), and
ortho2() calls.

I'm glad I brought it up, though, because I'm using new-style polygons
on a PI, but I want my code to run [the same] on all 4D machines. So
thanks for pointing out the difference between drawing lines and drawing
polygons.
