i can confirm that the shader is a lot slower than [pix_convolve].
on my system (linux, AthlonXP 2000+, NV31 (FX 5800)) it takes about
0.04ms to render a frame (including decompression of anim-1.mov and
texturing) with the glsl-shader and 0.02ms with pix_convolve.

since it runs on linux i guess it is more a vendor view of shader support.
