2019-03-08	Cycles OpenCL: Remove single program	Jeroen Bakker
	Part of the cleanup of the OpenCL codebase. Single program is not effective when using OpenCL, it is slower to compile and slower during rendering (when used in for example `barbershop` or `victor`).

2017-08-02	Cycles: Support "precompiled" headers in include expansion algorithm	Sergey Sharybin
	The idea here is that it is possible to mark certain include statements as "precompiled" which means all subsequent includes of that file will be replaced with an empty string. This is a way to deal with tricky include pattern happening in single program OpenCL split kernel which was including bunch of headers about 10 times. This brings preprocessing time from ~1sec to ~0.1sec on my laptop.
2017-06-10	Cycles: Add kernel to enqueue inactive rays	Mai Lavelle
	The queue will be used to make reuse of inactive threads to keep the GPU more busy.
2017-05-03	Cycles: Split kernel - sort shaders	Hristo Gueorguiev
	Reduce thread divergence in kernel_shader_eval. Rays are sorted in blocks of 2048 according to shader->id. On R9 290 Classroom is ~30% faster, and Pabellon Barcelone is ~8% faster. No sorting for CUDA split kernel. Reviewers: sergey, maiself Reviewed By: maiself Differential Revision: https://developer.blender.org/D2598
2017-03-29	Cycles: Make all #include statements relative to cycles source directory	Sergey Sharybin
	The idea is to make include statements more explicit and obvious where the file is coming from, additionally reducing chance of wrong header being picked up. For example, it was not obvious whether bvh.h was refferring to builder or traversal, whenter node.h is a generic graph node or a shader node and cases like that. Surely this might look obvious for the active developers, but after some time of not touching the code it becomes less obvious where file is coming from. This was briefly mentioned in T50824 and seems @brecht is fine with such explicitness, but need to agree with all active developers before committing this. Please note that this patch is lacking changes related on GPU/OpenCL support. This will be solved if/when we all agree this is a good idea to move forward.

2017-03-09	Cycles: split kernel_shadow_blocked to AO & DL parts	Hristo Gueorguiev
	Reduces memory allocation for split kernel. This allows for faster rendering due to bigger global size, specially when GPU memory is limited.

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.
