* The fullscreen quad is textured with the data from the

* Automatic shader generation NOT enabled.
If you have a filter that depends on a render target from
the auto-shader, you either need to set an auto-shader
attrib on the main camera or scene, or, you need to provide
these outputs in your own shader.
