The sampled color ramp data is passed to OSL as a color array. This has to be done as actual float[3] array though, since the Cycles float3 type actually contains 4 floats, leading to shifting color components in the array.
Additional parameter set functions for arrays have been added to the Cycles OSL interface for this purpose.
* Fix Musgrave Texture, used wrong Perlin Noise (0..1) instead of -1..1. Also added comment to noise_basis() to make it clear which noise type is used there.
* std::particle_index
* std::particle_age
* std::particle_lifetime
* std::particle_location
* std::particle_size
* std::particle_velocity
* std::particle_angular_velocity
Just as with SVM the rotation state attribute is currently disabled due to lack of a proper quaternion or matrix type in Cycles nodes.
* std::object_location
* std::object_index
* std::material_index
* std::object_random
Other object-based attributes can be added for particle info in the same way.
Instead of including util_string.h which in fact also defines some
symbols from util_string.cpp include STL's string header and directly
use std::string.
* reverted r50430
* removed 2 util_params.h includes from r50428, these were causing trouble with OIIO in CUDA compilation. The purpose of these was to define the ustring type, but can just use the standard string type from util_string as well.
* Added the Phong BRDF from the inbuilt OSL shader library.
This can be used in OSL shaders only for now:
* phong(normal N, float exponent)
* phong_ramp(normal N, float exponent, color colors[8]
This does not actually work: The context must not be shared between threads, but using the same context between different samples actually seems to prevent OSL from switching between shaders. The proper solution would be to ensure memory pooling works correctly.
This reverts commit 69f87e69258d6266dcb20f09f7e3d4021e663432.
Regular rendering now works tiled, and supports save buffers to save memory
during render and cache render results.

Various bug fixes by Sergey and Campbell.
* Fix for reading freed memory in some node setups.
* Fix incorrect memory read when synchronizing mesh motion.
* Fix crash appearing when direct light usage is different on different layers.
* Fix for vector pass gives wrong result in some circumstances.
* Fix for wrong resolution used for rendering Render Layer node.
* Option to cancel rendering when doing initial synchronization.
* No more texture limit when using CPU render.
* Many fixes for new tiled rendering.
Currently all shader functions check the OSL/SVM flag to dispatch to the appropriate backend. If this turns out to be a significant overhead (unlikely) this test should be moved out of the inner loop.
Fixes for API changes in OSL RendererServices:
* Added two new required get_matrix methods, from OSL RendererServices (otherwise the constructor fails). The two new matrix methods probably still need an implementation.
* Removed deprecated "get_pointcloud_attr_query" and "pointcloud". There are two new routines for pointclouds, function headers for those are there.
* Removed the (unused) PARTIO code parts from OSL. It was marked as not tested / not working, and due to the api changes here broken for sure. Code is still in svn history if needed.
