my questions are a combination of learning glsl and testing the features 
of gem. I am trying to get some shaders work in pd that I found included 
in xcode. these shaders that have a bunch of code in a seperate file 
(not vert and frag). I don't know how to implement this in glsl_program 
or any other gem render chain...

what is the noise command?
