You might be doing this already, I''m not familiar with that algorithm.

I see the circle as a symetrical object. If you can calculate one quarter of the circle about a (0,0) axis then you can just mirror those co-ordinates to draw the rest of the circle. Then you only have to calculate one quarter of the circle. However, I would think the Bresenham circle algo would be pretty fast.
