That's the easiest way to do it. The best way (fastest) is to call PaintRect
with a rectangle containing a single pixel. You have to make two toolbox calls
to draw a pixel, if you use MoveTo and LineTo. The fastest way to draw multiple
pixels is to create an offscreen bitmap and write directly to this bitmap. You
can then copy this bitmap to your grafport.
