​As another reference, you may like to consider some of my code. For
example, I wrote a Game of Life simulator
<http://geometrian.com/programming/projects/index.php?project=Game%20of%20Life>
that uses FBOs (it actually uses two IIRC; feedback requires ping-ponging).
The code is well-abstracted and reasonably well-tested, so it should serve
as a good example.
