[Fluxus] reaction-diffusion texture feedback example

[evan.raskob [lists]]

as part of markart 2009's "forking" concept I ported rdex-client from  
claude (claudius maximus) to fluxus - http://pixelist.info/2009/12/12/forking-claudes-rdex-client/

thanks to him and gabor especially for helping... i learned a lot  
about texture feedback in fluxus (created a simple example that i'll  
commit of doing gl feedback of the main scene) in the process.  there  
are a few snags, and there appears to be a memory leak with either  
textures or the shaders, because re-compiling the script a few times  
results in massive amounts of memory being eaten by my laptop.

enjoy! it's open source :)

cheers
