* Henyey-Greenstein scattering closure implementation. * Rename transparent to absorption node and isotropic to scatter node. * Volume density is folded into the closure weights. * OSL support for volume closures and nodes. * This commit has no user visible changes, there is no volume render code yet. This is work by "storm", Stuart Broadfoot, Thomas Dinges and myself.
