with regards to the noise functions in yafray based on Ken Musgrave's
original code.
I had left the 'Copyright' notice in the comments, and according to
Cyril Brulebois this is a problem. In fact, from what I understand this
makes it even impossible to use or modify the code in other software.
But since it is not a verbatim copy of the code but rather based on Musgrave's
work, he suggested I change it to explicitely state that it is in fact
based on the code from the 'Texturing & Modeling' book.
And since the yafray code is in turn based on the blender code, I better
adapt the blender code too.
This reminded me that I also have forgotten to include the copyright notice
in the mersenne twister rng code I used for the Python Noise module.
This does clearly state to include the original notice with any resdistributed
code, in modified form or not. So I added that too.
I hope that solves the problems.
- removed DL_MESH displist type!!!! Now store a DerivedMesh directly.
- May still be some issues left having to do with releasing this
at the right time (old code just splashed free_displist all
over the place).
Basically this provides three new things:
1. Choice of a list of noise-base functions, which can be used by the
current Clouds, Marble, Wood textures as well.
2. Three new texture types: Musgrave, Voronoi and DistortedNoise
3. Python access to noise functions (not for render!)
All of this together makes Blender's builtin procedural textures a LOT
more powerful. Here again, a full webpage should be made to show off all
possibilities, and explain some of the more scientific names for settings.
A good read on Musgrave textures can be found here:

About Voronoi:

I can't find official DistortedNoise docs easily... maybe its something
Eeshlo created himself.
I've spent some time to change the patch Eeshlo provided. Worth noting:
- created main texture "Musgrave" with 5 sub choices (instead of 5 new
main textures)
- added for all new textures the option to scale (zoom in out)
- added patch in do_versions to initialize variables
I hope the Python team will check on the Noise.c API. And include in docs!
