I did something like this to render stereo images for the old Fakespace BOOM 1
which was ntsc and black and white, one eye ran off the red channel and one off
the green. I wrote a procedure to step through the entire scene database and
remove all color from the materials (not the textures yet though). Then I used
RGBwritemask set to different things in the PreDraw callback for each channel.
