Fredrik Höglund	bfa2fc68e6	Rewrite the ARB lanczos shader to work with the Radeon R300 limitations. ... svn path=/branches/KDE/4.6/kdebase/workspace/; revision=1215505	2011-01-30 15:11:22 +01:00
Martin Gräßlin	78c4c7a86e	Lanczos filter available in GLES. ... It uses a default vertex shader, so the existing shader can be dropped.	2011-01-30 14:12:04 +01:00
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.
