Hi all :)

  well, I was expecting the GPU gems procedural parts before releasing the
patch in order to add others if needed but it didn't arrived.

 some use advice:

  at small scales (i.e the default textures values) it is a curl like
texture but at larger scales (size 1.0) and with 6 octaves in hard/soft
mode then it show the true planet procedural texture goodness :)


  Anyway, here's the patch, is very easy and don't disrup any existent
Blender code so is pretty safe:
