in case someone is looking for a blur shader for GEM, I put one online 
at http://www.parasitaere-kapazitaeten.net/Pd/blur_shader.
I haven't found a way to pass a matrix to the glsl_program, so the 
matrix has to be rendered every frame which is a challenge the GPU... If 
someone has a hint, how to deal with that in a more efficient way, 
please let me know.
the shader is similar to what pix_convolve does, and uses a linear fade.
