2017-09-05	Fix T52433: Volume Absorption color tint	Sergey Sharybin
	Need to exit the volume stack when shadow ray laves the medium. Thanks Brecht for review and help in troubleshooting!

2017-09-01	Fix T52472: VSE Audio Volume not set immediately	Joerg Mueller
	Audio mixing is done with volume interpolation. A new handle started at volume 1, now starting at volume 0 for a smooth fade in.
2017-09-01	Cycles: follow strict class naming convention	Campbell Barton

2017-08-31	Cycles: Cleanup, indentation and trailing whitespace	Sergey Sharybin

2017-08-31	Cycles: Fix typo in comment	Sergey Sharybin

2017-08-30	Fixing T52477 - switching from custom ray/triangle intersection code to the ↵	Stefan Werner
	one from util_intersection.h. This fixes the bug and makes the code more readable and maintainable.
2017-08-30	Cycles: Fix build with networking enabled	Mai Lavelle

2017-08-29	Fix Cycles Windows render errors with BVH2 CPU rendering.	Brecht Van Lommel
	One problem is that it was always using __mm_blendv_ps emulation even if the instruction was supported. The other that the emulation function was wrong. Thanks a lot to Ray Molenkamp for tracking this one down.
2017-08-28	Atomics: Use system headers directly, without bad level dependency to BLI	Sergey Sharybin
	This will make it easier to re-use library as-is in other projects, such as Cycles standalone repo for example.
2017-08-25	Fix for fix (tm): Residue of the debug code	Sergey Sharybin

2017-08-25	Fix mistake in previous tangent space optimization	Sergey Sharybin

2017-08-25	Cycles: Cleanup, naming of variable	Sergey Sharybin
	Always use b_ prefix for C++ RNA data.
2017-08-25	Cycles: Add assert to catch possibly wrong logic	Sergey Sharybin

2017-08-25	Cycles: Mark pixels with negative values as outliers	Lukas Stockner
	If a pixel has negative components, something already went wrong, so the best option is to just ignore it. Should be good for 2.79.
2017-08-25	Another optimization of tangent space calculation	Sergey Sharybin
	Don't use quick sort for small arrays, bubble sort works way faster for small arrays due to cache coherency. This is what qsort() from libc is doing actually. We can also experiment unrolling some extra small arrays, for example 3 and 4 element arrays. This reduces tangent space calculation for dragon from 3.1sec to 2.9sec.
2017-08-25	Optimize tangent space calculation by inlining functions	Sergey Sharybin
	Brings tangent space calculation from 4.6sec to 3.1sec for dragon model in BI. Cycles is also somewhat faster, but it has other bottlenecks. Funny thing, using simple `static inline` already gives a lot of speedup here. That's just answering question whether it's OK to leave decision on what to inline up to a compiler..
2017-08-25	Cycles: Add utility function to query current value of scoped timer	Sergey Sharybin

2017-08-25	Cycles: Correct logging of sued CPU intrisics	Sergey Sharybin

2017-08-25	Cycles: Fix stack overflow during traversal caused by floating overflow	Sergey Sharybin
	Would be nice to be able to catch this with assert as well, will see what would be the best way to do this/.\ Need to verify with Mai that this solves crash for her and maybe consider porting this to 2.79.
2017-08-24	Cycles: FIx issue with -0 being considered a non-finite value	Sergey Sharybin

2017-08-24	Fix Cycles CUDA transparent shadow error after recent fix in c22b52c.	Brecht Van Lommel
	Fishy cat benchmark was rendering with wrong shadows. Cause is unclear, adding printf or rearranging code seems to avoid this issue, possibly a compiler bug. This reverts the fix and solves the OSL bug elsewhere.
2017-08-24	Code cleanup: remove shader context.	Brecht Van Lommel
	This was needed when we accessed OSL closure memory after shader evaluation, which could get overwritten by another shader evaluation. But all closures are immediatley converted to ShaderClosure now, so no longer needed.
2017-08-23	Cycles: Add maximum depth stat to bvh builder	Mai Lavelle

2017-08-23	Fix implementation of atomic update max and move to a central location	Mai Lavelle
	While unlikely to have had any serious effects because of limited use, the previous implementation was not actually atomic due to a data race and incorrectly coded CAS loop. We also had duplicates of this code in a few places, it's now been moved to a single location with all other atomic operations.
2017-08-23	Fix T51805: Overlapping volumes renders incorrect on AMD GPU	Sergey Sharybin
	We need to make sure we can store all volume closures for all objects in volume stack. This is a bit tricky to detect what would be the "nestness" level of volumes so for now use maximum possible stack depth. Might cause some slowdown, but better to give reliable render output than to fail quickly. Should be safe for 2.79 after extra eyes.
2017-08-22	Fix panorama render crash with split kernel, due to incorrect buffer pointer.	Brecht Van Lommel
	Also some refactoring to clarify variable usage scope.
2017-08-21	Cycles: reorganize Performance panel layout, move viewport BVH type to debug.	Brecht Van Lommel

2017-08-21	Cycles: attempt to recover from crashing CUDA/OpenCL drivers on Windows.	Brecht Van Lommel
	I don't know if this will actually work, needs testing. Ref T52064.
2017-08-21	Revert "Cycles: remove square samples option."	Brecht Van Lommel
	This reverts commit 757c24b6bceaeeae95f743b72b6a7040880a0ebf. We'll revisit this when doing deeper sampling changes.
2017-08-21	Fix T52470: cycles OpenCL hair rendering not working after recent changes.	Brecht Van Lommel

2017-08-20	Code cleanup: deduplicate some bsdf node methods.	Brecht Van Lommel

2017-08-20	Cycles: support baking normals plugged into BSDFs, averaged with closure weight.	Brecht Van Lommel

2017-08-20	Code cleanup: remove copy of shader graph for bump, no longer needed.	Brecht Van Lommel

2017-08-19	Fix T52452: OSL trace broken after shadow catcher recent changes.	Brecht Van Lommel
	We should only early out with any hit in BVH traversal if the only visibility bits used are opaque shadow. Not when opaque shadow is one of multiple bits.
2017-08-19	Code cleanup: move rng into path state.	Brecht Van Lommel
	Also pass by value and don't write back now that it is just a hash for seeding and no longer an LCG state. Together this makes CUDA a tiny bit faster in my tests, but mainly simplifies code.
2017-08-19	Fix T52443: Cycles OpenCL build error after recent mesh lights changes.	Brecht Van Lommel

2017-08-17	Cycles: Fix for a division by zero that could happen with solid angle ↵	Stefan Werner
	triangle light sampling
2017-08-17	Improved triangle sampling for mesh lights	Stefan Werner
	This implements Arvo's "Stratified sampling of spherical triangles". Similar to how we sample rectangular area lights, this is sampling triangles over their solid angle. It does significantly improve sampling close to the triangle, but doesn't do much for more distant triangles. So I added a simple heuristic to switch between the two methods. Unfortunately, I expect this to add render time in any case, even when it does not make any difference whatsoever. It'll take some benchmarking with various scenes and hardware to estimate how severe the impact is and if it is worth the change.

2017-08-15	Cycles/BI: Add a pixel size option for speeding up viewport rendering	Lukas Stockner
	This patch adds "Pixel Size" to the performance options, which allows to render in a smaller resolution, which is especially useful for displays with high DPI.

2017-08-14	Cycles: Guard memcpy to potentially re-allocating memory with lock	Sergey Sharybin
	Basically, make re-alloc and memcpy from the same lock, otherwise one thread might be re-allocating thread while another one is trying to copy data there. Reported by Mohamed Sakr in IRC, thanks!
