The tile equalizer decomposes the rendering of a single view into evenly-sized
tiles. While this may be abused for your needs, you could simply write a loop

This is what Equalizer does. Did you run the example I mentioned?

One channel, used as source and dest does work. See the attached diff for what
you have in mind.
