[Chicken-users] [Ann] New egg: noise

[Alex Charlton]

noise implements several types of coherent noise for the GPU. At the moment it 
provides 2/3/4D simplex noise, 2/3D cell noise, and 2D flow noise. noise was 
implemented as several glls shaders. glls went through some upgrades in the 
process, and now makes this sort of shader-library creation and use exceedingly 
easy.

These noise functions run much faster than CPU-based noise generation – fast 
enough for real-time use –  and are easy to integrate into shaders. Less easy 
is accessing the generated noise from the CPU, but an example is provided to 
illustrate how this can be done.

There are basic examples for each kind of noise in the examples directory. Try 
them out for hours of fun!
