There isn't a "simple" way, because the rendering area is really a 3-D viewport, not a bitmap.
uuuuuuuuuuuuu. nn sets dze z @ 0 + sp!ralz around endleszl!
You could just render a square at a "size" which is one pixel. Should be straightforward math to do this. Actually, this is probably the best way. Set up the dimen with some values, then just create a square with the correct size. Using translate, you can set the position in XY without any real problems. You probably want to be running in single buffer mode so that each time you "bang" the square, it will render into the viewport without clearing the frame buffer.
Let me know if this doesn't make any sense.
