Cycles: merge of cycles-x branch, a major update to the renderer This includes much improved GPU rendering performance, viewport interactivity, new shadow catcher, revamped sampling settings, subsurface scattering anisotropy, new GPU volume sampling, improved PMJ sampling pattern, and more. Some features have also been removed or changed, breaking backwards compatibility. Including the removal of the OpenCL backend, for which alternatives are under development. Release notes and code docs: https://wiki.blender.org/wiki/Reference/Release_Notes/3.0/Cycles https://wiki.blender.org/wiki/Source/Render/Cycles Credits: * Sergey Sharybin * Brecht Van Lommel * Patrick Mours (OptiX backend) * Christophe Hery (subsurface scattering anisotropy) * William Leeson (PMJ sampling pattern) * Alaska (various fixes and tweaks) * Thomas Dinges (various fixes) For the full commit history, see the cycles-x branch. This squashes together all the changes since intermediate changes would often fail building or tests. Ref T87839, T87837, T87836 Fixes T90734, T89353, T80267, T80267, T77185, T69800

Cycles: remove prefix from source code file names Remove prefix of filenames that is the same as the folder name. This used to help when #includes were using individual files, but now they are always relative to the cycles root directory and so the prefixes are redundant. For patches and branches, git merge and rebase should be able to detect the renames and move over code to the right file.

Cycles: add Path Guiding on CPU through Intel OpenPGL This adds path guiding features into Cycles by integrating Intel's Open Path Guiding Library. It can be enabled in the Sampling > Path Guiding panel in the render properties. This feature helps reduce noise in scenes where finding a path to light is difficult for regular path tracing. The current implementation supports guiding directional sampling decisions on surfaces, when the material contains a least one diffuse component, and in volumes with isotropic and anisotropic Henyey-Greenstein phase functions. On surfaces, the guided sampling decision is proportional to the product of the incident radiance and the normal-oriented cosine lobe and in volumes it is proportional to the product of the incident radiance and the phase function. The incident radiance field of a scene is learned and updated during rendering after each per-frame rendering iteration/progression. At the moment, path guiding is only supported by the CPU backend. Support for GPU backends will be added in future versions of OpenPGL. Ref T92571 Differential Revision: https://developer.blender.org/D15286
