There is a cornercase when the user edits an uvmap, that is not part of
the material (yet). When this is the case the uvmap was not added to the
uv buffer and the 'pos' alias was not created.
This change will always request the active uv map when uv editing.

Seems like we need to set the error with the evaluated ModifierData.
Pass this to 'surfacedeformBind' and report with that.

This integrates hair collisions with the new cloth collision system,
greatly improving reliability, and reducing the amount of hair-specific
code paths in the cloth code.
The removes all the point constraint based collision stuff, instead
implementing segment impulse based collisions, using the same collision
response code as the normal cloth solver.
The hair system can now also collide with the emitter if it is a
collision object.

This avoids the problem where Blender doesn't start because
the PYTHONPATH points to an incompatible Python version,
see T72807.
Previously we chose to assume people who set the PYTHONPATH know what
they're doing, however users may have set this for non Blender projects.
So it's not obvious that this is the cause of Blender not to launch
on their system.
To use Python's environment vars, pass the argument:
--python-use-system-env
Note that this only impacts Python run-time environment variables
documented in `python --help`, Access from `os.environ` remains.
Old pre 2.5 files may have had non active spaces stored that doen't have
a header. The 2.5 versioning only added headers for active spaces, not
inactive (so invisible) ones.
Newer versioning code assumed there to always be a header though.
Inserted a version patch to make sure there's always a header now.
Fixes error reported to Debian,
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=949035.
The last handle wasn't corrected, also, there is no reason
to flip the handles while sorting (checking the same handles many times)
move this into it's own loop.
`ARegion.alignment` unfortunately is a mixture of value and bitflag
enumerations. When checking for left/right/top/bottom region alignment,
the flags have to be masked out usually.
Most of the fixed cases here probably didn't cause issues in practice,
but could in fact break at any point when surrounding logic changes.
In fact the assert in #region_visible_rect_calc() failed in an older
file from https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=949035. This
fixes it.
Outliner tree building code was not handling properly empty libraries
(i.e. Lib datablocks in our bmain which have no used actual data
anymore).
Main issue here is unclean states of indirect hierarchies of linking
involving several libraries after undo operation.
This is not a critical issue though, just annoying and untidy.
Just some rewording of the documentation of `Particle.uv_on_emitter()`,
so that it no longer refers to 'derived mesh' but 'evaluated mesh', and
document that it expects a modifier from an evaluated object.
No functional changes.
The floating "Move" redo panel showed transform values with less
precision than in other places (e.g. sidebar and properties editor).
With Millimeters as unit it would even round to full integers, which
may be an issue since you typically work at higher precisions with this
unit.
Note that this only applies to the visual precision, internally we use
full floating point `float`s still.
Fixes T70367.
Previously the button would only show up in the status-bar located in
the same window that had the screen with the animation timer.
I don't see a reason not to show the button in all status-bars instead,
other animation feedback is also displayed in all windows.
Fixes T72194.
Based on @fclem's suggestion in D6421, this commit implements support for
storing all tiles of a UDIM texture in a single 2D array texture on the GPU.
Previously, Eevee was binding one OpenGL texture per tile, quickly running
into hardware limits with nontrivial UDIM texture sets.
Workbench meanwhile had no UDIM support at all, as reusing the per-tile
approach would require splitting the mesh by tile as well as texture.
With this commit, both Workbench as well as Eevee now support huge numbers
of tiles, with the eventual limits being GPU memory and ultimately
GL_MAX_ARRAY_TEXTURE_LAYERS, which tends to be in the 1000s on modern GPUs.
Initially my plan was to have one array texture per unique size, but managing
the different textures and keeping everything consistent ended up being way
too complex.
Therefore, we now use a simpler version that allocates a texture that
is large enough to fit the largest tile and then packs all tiles into as many
layers as necessary.
As a result, each UDIM texture only binds two textures (one for the actual
images, one for metadata) regardless of how many tiles are used.
Note that this rolls back per-tile GPUTextures, meaning that we again have
per-Image GPUTextures like we did before the original UDIM commit,
but now with four instead of two types.

Not sure how the WorkSpaceLayout.screen pointer could end up being NULL,
but apparently that happens, or at least happened with older files.
Rather than just adding NULL-checks, prefer not keeping around those
invalid layouts at all.
