2017-11-05	Cycles: reduce closure memory usage for emission/shadow shader data.	Brecht Van Lommel
	With a Titan Xp, reduces path trace local memory from 1092MB to 840MB. Benchmark performance was within 1% with both RX 480 and Titan Xp. Original patch was implemented by Sergey. Differential Revision: https://developer.blender.org/D2249
2017-10-04	Code refactor: zero render buffers outside of kernel.	Brecht Van Lommel
	This was originally done with the first sample in the kernel for better performance, but it doesn't work anymore with atomics. Any benefit was very minor anyway, too small to measure it seems.
2017-10-04	Code refactor: remove rng_state buffer and compute hash on the fly.	Brecht Van Lommel
	A little faster on some benchmark scenes, a little slower on others, seems about performance neutral on average and saves a little memory.
2017-10-04	Code refactor: add WorkTile struct for passing work to kernel.	Brecht Van Lommel
	This makes sharing some code between mega/split in following commits a bit easier, and also paves the way for rendering multiple tiles later.
2017-09-21	Code cleanup: simplify kernel side work stealing code.	Brecht Van Lommel

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.
2017-08-19	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.
2017-08-13	Code cleanup: make L_transparent part of PathRadiance.	Brecht Van Lommel

2017-08-13	Code cleanup: make DebugData part of PathRadiance.	Brecht Van Lommel

2017-08-12	Code cleanup: remove unused Cycles random number code.	Brecht Van Lommel

2017-03-27	Cycles: Remove ccl_addr_space from RNG passed to functions	Hristo Gueorguiev
	Simplifies code quite a bit, making it shorter and easier to extend. Currently no functional changes for users, but is required for the upcoming work of shadow catcher support with OpenCL.
2017-03-13	Cycles: Cleanup, wipe obviously outdated parts of split kernel comments	Sergey Sharybin

2017-03-09	Cycles: SSS and Volume rendering in split kernel	Hristo Gueorguiev
	Decoupled ray marching is not supported yet. Transparent shadows are always enabled for volume rendering. Changes in kernel/bvh and kernel/geom are from Sergey. This simiplifies code significantly, and prepares it for record-all transparent shadow function in split kernel.
2017-03-08	Cycles: Fix indentation	Mai Lavelle

2017-03-08	Cycles: Remove sum_all_radiance kernel	Mai Lavelle
	This was only needed for the previous implementation of parallel samples. As we don't have that any more it can be removed. Real reason for removal tho is this: `per_sample_output_buffers` was being calculated too small and artifacts resulted. The tile buffer is already the correct size and calculating the size for `per_sample_output_buffers` is a bit difficult with the current layout of the code. As `per_sample_output_buffers` was only needed for `sum_all_radiance`, removing that kernel and writing output to the tile buffer directly fixes the artifacts.
2017-03-08	Cycles: Split path initialization into own kernel	Mai Lavelle
	This makes it easier to initialize things correctly in the data_init kernel before they are needed by path tracing.
