2014-01-17	Fix T37706: avoid cycles crash when using a stack that exceeds SVM stack limits.	Brecht Van Lommel
	This should be pretty rare, the shader in question had many parallel node links because of copying the nodes many times, which is inefficient to run anyway.
2014-01-16	Workaround for avx assembler not compiling with vanilla gcc ( with openMP case )	Jens Verwiebe

2014-01-16	Fix compilation of Cycles AVX kernel with cmake.	Thomas Dinges

2014-01-16	Cycles: Add an AVX kernel for CPU rendering.	Thomas Dinges
	* AVX is available on Intel Sandy Bridge and newer and AMD Bulldozer and newer. * We don't use dedicated AVX intrinsics yet, but gcc auto vectorization gives a 3% performance improvement for Caminandes. Tested on an i5-3570, Linux x64. * No change for Windows yet, MSVC 2008 does not support AVX. Reviewed by: brecht Differential Revision: https://developer.blender.org/D216

2014-01-13	Fix T38190: Linux tablet: Issue with XInput/GHOST?	Bastien Montagne
	With edits by Campbell, thanks! Looks like in some cases (driver dependent?), `XDeviceMotionEvent` get generated with only part of expected data (e.g. only x coordinate, only pressure, etc.), data which did not change since last event being NULL. We know which data to actually handle with `XDeviceMotionEvent.first_axis` and `XDeviceMotionEvent.axes_count` values.

2014-01-13	Fix cycles texture crash on win x86-64 + msvc 11	Sv. Lockal
	Use union for __m128 aliasing; while gcc supports no-strict-aliasing attribute, unions are the most common way to deal with __m128 in msvc.

2014-01-08	Cycles: workaround for noise performance regression in CUDA 5.5	Sv. Lockal
	Use manual ternary operation widening in grad(). Without it nvcc 5.5 produces multiple branch splits with very big branches (because of inlining). This solves 19% performance regression for BMW1M-MikePan.blend. Also remove one redundant instruction in perlin SSE (when h == 12 or h == 14, then h is always >= 4).

2014-01-07	Fix CUDA/OpenCL compile errors in scattering commit.	Brecht Van Lommel

2014-01-07	Cycles Volume Render: scattering support.	Brecht Van Lommel
	This is done by adding a Volume Scatter node. In many cases you will want to add together a Volume Absorption and Volume Scatter node with the same color and density to get the expected results. This should work with branched path tracing, mixing closures, overlapping volumes, etc. However there's still various optimizations needed for sampling. The main missing thing from the volume branch is the equiangular sampling for homogeneous volumes. The heterogeneous scattering code was arranged such that we can use a single stratified random number for distance sampling, which gives less noise than pseudo random numbers for each step. For volumes where the color is textured there still seems to be something off, needs to be investigated.
