I would try to replace any method calls in a heavy inner loop such as the
one above with the code that those methods actually perform. This removes
any method calling overhead, and has proven to be a nice performance
improvement - atleast for my programs (e.g. my simplistic 3D engine).
If your shadePixel method does some heavy work it could overshadow the
method calling overhead though, in which case my suggestion won't give much
improvement.
