d7886ee759 Color management: Further relax threshold for sRGB detection
Apparently, the SSE optimization in the OCIO is not nearly as accurate
as a naive implementation. For example, exponent transform of 1 gives
result of 1.000024.

d50b139b06 Color management: Relax threshold for sRGB detection
The current core was only detecting sRGB transform when it is defined
as sRGB->Linear using srgb.spi1d. If it is defined as an inverse of
Linear->sRGB using srgb_inv.spi1d, or as an analytical formula using
ExponentWithLinearTransform then the code did not detect the color
as sRGB on anything by Apple Silicon platform.

The naming of the checks could be improved to make it more clear that
the check is only used to allow lossless access to 8bit sRGB textures.

b77e6aaa0f Fix warnings in Cycles graph test output
Harmless, but is quite noisy and easy to avoid.

ec04870091 Fix Cycles standalone float textures not taking into account colorspace metadata
This got lost in colorspace refactoring at some point. It probably does not
affect many files in practice, but implementation was wrong regardless.

9cfc7967dd Cycles: use SPDX license headers
* Replace license text in headers with SPDX identifiers.
* Remove specific license info from outdated readme.txt, instead leave details
  to the source files.
* Add list of SPDX license identifiers used, and corresponding license texts.
* Update copyright dates while we're at it.

fd25e883e2 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.

d7d40745fa Cycles: changes to source code folders structure
* Split render/ into scene/ and session/. The scene/ folder now contains the
  scene and its nodes. The session/ folder contains the render session and
  associated data structures like drivers and render buffers.
* Move top level kernel headers into new folders kernel/camera/, kernel/film/,
  kernel/light/, kernel/sample/, kernel/util/
* Move integrator related kernel headers into kernel/integrator/
* Move OSL shaders from kernel/shaders/ to kernel/osl/shaders/

For patches and branches, git merge and rebase should be able to detect the
renames and move over code to the right file.
