Bitmap Scaling Algs

[Brent L. Bates AAD/TAB MS361 x42854]

   I am not sure what you are trying to do, but, maybe this will help.
When I display bitmap images, I either plot each pixel as a point, flat
shaded polygon, or a Gouraud shaded polygon.  This is slower than using
pixel routines, but it is very easy to scale the image up or down using
ortho or techniques.
