[jitter] multiples and shaders

If you have N shaders for M object instances where N is significantly  
smaller than M, one thing which is possible is to use N instances of  
jit.gl.multiple for each different shader. Then before sending the  
items to jit.gl.multiple to render, separate them into N different  
matrices accordingly. The same thing applies to textures, where even  
though you can specify a different shader to jit.gl.multiple, it is  
most likely more efficient to sent the texture once per  
jit.gl.multiple render, if the number of textures N is significantly  
smaller than the M object instances being rendered.

Hope this makes sense.
