Fredrik Höglund	119c06e403	Make the lanczos shader use a fixed number of iterations in the loop. ... This makes it possible for the GLSL compiler to unroll it, which also avoids the need to use relative addressing. With this change the shader should hopefully work with the R300G driver. The unused kernel weights are set to zero so they don't contribute to the end result. Thanks to Tom Stellard and Marek Olšák for their suggestions on how to solve this problem.
