Replace plain-text type information with the type syntax used
for Python's type annotations as it's more concise, especially for
callbacks which often didn't include useful type information.
Note that this change only applies to inline doc-strings,
generated doc-strings from RNA need to be updated separately.
Details:
- Many minor corrections were made when "list" was incorrectly used
instead of "sequence".
- Some type information wasn't defined in the doc-strings and has been
added.
- Verbose type info would benefit from support for type aliases.
Add-ons may attempt to load the GPU module in background mode when no GPU
context has been initialized yet. This would give an error on import.
If then later the GPU context does get initialized, for example for a
render engine, import would still fail as the module is cached.
This reverts commit d7f124f06f, and again
throws errors in methods and constructors instead of module import.

Compute shaders are required since 4.0. There was one occasion where
an older AMD driver failed and support was turned off. This driver
is now marked unsupported.
This PR includes:
- removing the check in viewport compositing
- remove properties from system info
- always construct draw manager.
- remove unused pass logic in draw hair/curves
- add deprecation warning when accessed from python

This patch adds the maximum number of supported image units to the GPU
capabilities module. Currently, the GPU module assume a maximum of 8
units, so the patch is not currently particularly useful, but we can
consider committing it for the future anyways.

Motivation: When discussing with @Jeroen-Bakker and @aras_p about how to
approach sorting when rendering Gaussian splats in Blender, we realised that
compute shaders could help there (and have many other use cases), and that also
due to Blender 4.0 being on OpenGL >= 4.3, we can now rely on compute shaders
existing.
This PR is an initial pass for that functionality. It comes with a Python example, which
runs a compute shader and saves the output to a texture, which is then rendered in the
viewport.
There is no exposed support for storage buffers yet, but I expect I'll be able to work on
them soon if this is accepted.
The newly added parts are:
1. `gpu.compute.dispatch()`
2. a way set the compute source to `GPUShaderCreateInfo`: `shader_info.compute_source()`
3. a way to set the image store for `GPUShaderCreateInfo`: `shader_info.image()`
4. a way to set the `local_group_size` for `GPUShaderCreateInfo`: `shader_info.local_group_size(x,y,z)`
5. a way to get `max_work_group_size` from capabilities: `gpu.capabilities.max_work_group_size_get(index)`
6. a way to get `max_work_group_count` from capabilities: `gpu.capabilities.max_work_group_count_get(index)`

Blender 4.0 requires OpenGL 4.3 which always support SSBO's.
Platforms that don't support enough SSBO bind points will be marked
as unsupported.
Users who start Blender on those platforms will be informed via a
dialog. This PR also updates the `--debug-gpu-force-workarounds`
to match our minimum requirements. Note that some bugs are still
there that should be solved in other PRs:
* Workbench only renders the object using a unit matrix this is because
there is a bug in the workaround for shader_draw_parameters
* Navigating with middle mouse button is not working. Unsure what the
cause is, but might be a missing feature check in the OpenGL backend.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
Add a High Dynamic Range option in the Color Management > Display panel.
This enables display of extended color ranges above 1.0 for the 3D
viewport, image editor and render previews.
This requires a monitor that can display HDR colors, and a view
transform designed for HDR output. The Standard view transform works,
but Filmic does not as it was designed to bring values into the 0..1
range for SDR displays.
This patch is limited to allowing the display to visualize extended
colors, but does not include future looking work to better integrate HDR
into the full workflow.
It is implemented by rendering to high bit-depth texture formats for
the user interface, and uncapping the color range in color management.
