Hi all,
see also this thread for maybe a different idea. We also need multiple
(but variable) passes for an image processing algorithm.

P.S. The solution is practicaly for implementing iterative image
processing algorithms with osgPPU for example.
I've been thinking about the same issue, rendering a subgraph repeatedly
with different texture input and FBO setup output, for purposes of depth
peeling. Overriding traverse in a custom Group node, or maybe even
overriding drawImplementation in a custom Drawable, seems like the way
to go.
