[jitter] Re: Slab on a jit.gl.model

Ugh. 
If I had a nickel for every time someone got snarled up working with 
that particle/model example...

Anyways, I think you'd be well served to look at jit.gl.multiple for 
doing the particle drawing stuff, or using "to_texture" instead of 
@capture to do your rendering to texture.  I don't think capture will do 
what you want it to with the jit.iter method of particle rendering.  
Attached you'll find a version of your particle drawing -> capture stuff 
that works.  I removed all the other stuff for the sake of legibility...

Best,
Andrew B.
