  Download the free version of Claw (www.rrsoftware.com) and look at the
"bigjob" demo program to see a simple program that draws on a window.
To see an example of drawing individual pixels, go to
http://www.adapower.com/index.php?Command=Class&ClassID=GUIExamples&CID=435
and get the source code for Orbitals.  That program shows a 3-D
representation of the probability density of Hydrogen electron orbitals
per the Schrodinger equation, which you probably don't care about.  ;)
But in the "procedure When_Draw" in display.adb you'll see a call to
Claw.Bitmaps.Set_Pixel, which is what you want.
