The comment of `solve_cubic()` put the coefficients of the to-be-solved
cubic equation in the wrong order. This is now fixed.
No functional change, just a comment fix.
When the line was very thin the precision of the thickness
calculation was not precise enough.
The algorithm has been improved. This affects SVG and PDF.
* Make it clearer that contrib isn't shipped with releases, by already excluding it in beta.
* Improve the UI by hiding the "Testing" enum item in these case.

In preparation to sanatize the mask texture and color texture in sculpt code. In sculpt
mode the mask texture is read from mtex, leaving the mask_mtex when we want to use color
textures in sculpt mode.
Having all packages on one line made reviewing changes difficult.
Also note why Python modules are needed (with some TODO's where I wasn't
able to find any reason given for their inclusion).
The PKGCONFIG file exposes the OPUS include: requiring <opus/opus.h>
to be replaced with <opus.h>. Manipulate the PKGCONFIG file instead of
patching the source since the small change is only needed in one place.
Meson is built as part of external_python_site_packages,
without this dependency it would be called before being built.
Also remove Meson as a build requirement since the version is used.
Adds an early return if Position/Offset inputs won't lead
to any changes in the Geometry.
It now also compares with the read-only Position attribute instead of
getting it for write only, to work correctly with Copy-on-Write.
Before, the `is_same`-check only worked for geometry created
in the node tree.

There has been an attempt to reorganize this part, however, it seems that didn't compile on HIP, and is reverted in
rBc2dc65dfa4ae60fa5d2c3b0cfe86f99dcb5bf16f. This is another attempt of refactoring. as I have no idea why some things don't work on HIP, it's
best to check whether this compiles on other platforms.
The main changes are creating a new struct named `MeshLight` that is shared between `KernelLightDistribution` and `KernelLightTreeEmitter`,
and a bit of renaming, so that light sampling with or without light tree could call the same function.
Also, I noticed a patch D16714 referring to HIP compilation error. Not sure if it's related, but browsing
https://builder.blender.org/admin/#/builders/30/builds/7826/steps/7/logs/stdio, it didn't work on gfx1102, not gfx9*.

The OpenVDB delay loading of voxel leaf data using mmap works poorly on network
drives. It has a mechanism to make a temporary local file copy to avoid this,
but we disabled that as it leads to other problems.
Now disable delay loading entirely. It's not clear that this has much benefit
in Blender. For rendering we need to load the entire grid to convert to NanoVDB,
and for geometry nodes there also are no cases where we only need part of grids.
To avoid issues with lights being either skipped or sampled unnecessarily
when the exposure is set low or high.

* preempt_attr was copied from CUDA, but not used in HIP.
* Remove shadowed variable before conditional in EnvironmentTextureNode code.

Expand the motion path frame range options with an extra option "Manual
Range". When chosen, Blender will not automatically update the path
range any more.
Additionally, the start/end frame fields are greyed out in the UI when
one of the automatic range options is selected (i.e. all but the new
"Manual Range" one). It is still possible to set the start/end frame
temporarily, but the original behaviour (of recomputing those on update)
remains.

The catalog tree is a unit on its own, and should be tested separately.
This makes the testing files smaller and more focused, which can help
maintaining them.
This manages setting up asset library directories for testing, which is
useful for testing multiple asset library related compontents. So move
it to a common header. No reason to squeeze everything into one file
then.
Compile each static shader using shaderc to Spir-V binaries.
The main goal is to make sure that the GLSL created using ShaderCreateInfo and able to compile to Spir-V.
For the second stage a correct pipeline needs to be created and some shader would need more
adjustments (push constants size).
With this patch future changes to GLSL sources can already be checked against vulkan, without the
backend finished.
Mechanism has been tested using MacOS and MoltenVK. For other OS, we should finetune CMake
files to find the right location to shaderc.

Previously, it wouldn't detect the case when one mesh had an attribute
that the other one did not. Not sure if this always was the case or whether
this less strict test was implemented accidentally at some point.
But it below the `else` case to make the control flow clearer, since
in the end that is more important. Also clarify the wording and fix
grammar slightly.
