usesrcdim equivalent with opengl slabs?

    I made a little jitter hack that makes a movie into horizontal lines just by changing the srcdim for the matrix. I want to apply this effect to incoming opengl textures. Is there a similar trick I can do with slabs so I don't have to waste CPU rendering to a matrix?
    Here is the original patch with matrices:
    Edit: On a similar note, how can I use slab processing to change color information such as hue, saturation and brightness? It seems like it should be simple but I'm having a hard time finding information on the various effects you can do with slabs.

      Slab helpers for saturation and brightness are at max/examples/jitter-examples/render/slab-helpers/color In slab-helpers/texdisplace look at td.resample.jxs for srcdim changes
