963c638a5b Fix #131132: Cycles reading packed multilayer EXR wrong
Rewrite Blender image loading to avoid RNA API, which we are moving away
from. This makes it easier to support multilayer EXR.

91346755ce Cleanup: use '#' prefix for issues instead of 'T'
Match the convention from Gitea instead of Phabricator's T for tasks.

cacfaaa9a5 Fix T92416: First render with unknown image colorspace looks different
The issue here was that the Barbershop benchmark scene was saved with a
custom OCIO config, which leads to some textures having a unknown
colorspace when loading with a default installation.

This is automatically fixed by Blender during image loading, but since
Cycles queried the colorspace before actually loading the image, it
didn't get the updated value in the first render.

To fix this, just re-query the colorspace after the image is loaded.

Note that non-packed images still get treated as raw data if the
colorspace is unknown, but this is at least consistent and doesn't
magically change when you press F12 a second time.

284a3431ae Cycles: Fix rendering of packed UDIM tiles with different sizes
The packed image loader was not aware of the fact that UDIM tiles
can be of a different size.

Exposed Python API required to access this information. It has the
same complexity as the "regular" packed files: in both cases the
ImBuf will be acquired and released to access the information.

While the current workflow of packing UDIMs is not very streamlined,
it is still possible and is something what the studio is using here.

Test file:
{F13130516}

Expected behavior achieved with this patch: a bigger checker board
pattern in viewport render

Actual behavior prior to this patch: either memory corruption, or
wrong/black render result on the plane

33f5e8f239 Cycles: load 8 bit image textures as half float for some color spaces
For non-raw, non-sRGB color spaces, always use half float even if that uses
more memory. Otherwise the precision loss from conversion to scene linear or
sRGB (as natively understood by the texture sampling) can be too much.

This also required a change to do alpha association ourselves instead of OIIO,
because in OIIO alpha multiplication happens before conversion to half float
and that gives too much precision loss.

578771ae4d UDIM: Add support for packing inside .blend files
This completes support for tiled texture packing on the Blender / Cycles
side of things.

Most of these changes fall into one of three categories:
- Updating Image handling code to pack/unpack tiled and multi-view images
- Updating Cycles to handle tiled textures through BlenderImageLoader
- Updating OSL to properly handle textures with multiple slots

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.

2fd657db5b Fix T93560: crash with image paint undo and cycles preview render
Cycles preview rendering could free the image buffers being used by drawing in
another thread due to a race condition. This race condition was unlikely before,
but now that preview renders are started right before we draw the image in the
image editor or load it as a texture in the 3D viewport, it's likely to happen.

As we are close to release this is too risky to fix properly, just avoid freeing
the cache for preview renders instead and accept increased memory usage in some
cases.

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.
