I banged my head against a wall for days trying to get smooth shading of 3d
objects correct. (assembler on a 1980's ECL super computer) until the light
went on and I used center pixel coordinates for the color calculations. The
integer x/y pixel positions didn't cut it. Had to go center pixel floating
point.
