And the first thing I noticed was that you do things the other way around : you actually plot a pixel for every angle. This will result in gaps for large radius and a lot of overdraw for small radius. What you should do is start from the screen coordinates and compute the corresponding angles to figure the UV coordinate. I tried to make a sphere mapping, didn't do all the rotations but the basic rendering loop, and noticed that the size of the texture changes dramatically the speed. I don't remember if that was just in Opera or also in Firefox. Chrome was super slick.
