Cycles: Fixed stupid typo in PMJ02 generator.

Cycles: Fixed OpenCL build.

Cycles: Fixed some more stupid bugs in the PMJ02 sampler.

Cycles: Added random shuffling to PMJ generation.

Progressive Multi-Jittered sequences still had some correlations between dimensions.
Now there's some added random permutation for higher dimensions.

Cycles: Disabling adaptive sampling for CMJ and Sobol

Only Progressive Multi Jitter has the properties we need for
adaptive sampling, so disable it for other sampler types.

Cycles: Moved adaptive rendering to use PMJ sampler.

Cycles: Improved scrambling of PMJ sequence

Pixar notes that progressive multi-jittering doesn't work that well
with Cranley-Patterson rotation and suggests random digit scrambling
instead.

Cycles: Made PMJ sampler compile on Windows

Cycles: Added Progressive Multi-Jittered Sampling.

Cycles: Adaptive sampling now influences neighboring pixels.

When a pixel requests new samples, it now also makes its neighbors require new samples.
Done via a simple box filter.

Cycles: Added sample count AOV.

Cycles: Adaptive sampling on CPU shows per tile progress again.

Cycles: Updated adaptive sampling error metric.

Cycles: More improvements for adaptive sampling.

Cycles: Moved adptive stopping from host to kernel.

Cycles: Quick and dirty test of an adaptive sampler.

Added support for debug versions of OpenImageDenoise Windows DLLs.

Compositor: More fixes for OIDN build on Windows.

build_environment: Fixed Windows build with static OpenImageDenoise.

build_environment: Fixed FindOpenImageDenoise.cmake.
