Implements T89789, T89792, custom grid (described as dynamic grid in
T78389) and UV grid snapping (T78391)
Replaces the default UV editor grid with 2 new types of grid :
* Custom grid: Allows the user to create an NxN grid, where the value
of N is specified by the user.
* Subdividing grid: Subdivides the UV editor grid when the user
zooms in the viewport and vice versa when zooming out.
UV snapping improvements :
* Increment snapping: Increment values for snapping are calculated based
on which grid type is being used in the UV editor
(subdividing or custom). In general the increment value is equal to
the distance between 2 visible grid lines.
* Absolute grid snap: New toggle added to increment snapping option in
the UV editor, allows UV grid snapping during translation.

Using a RenderResult (or a Viewer) was never really working (think you
cant get a real ImBuff from these) -- cannot use it as a clone, stencil
or canvas [Single Image paint texture slot].
In the case of using it as a 2D paint clone image this would also crash
[due to the Image Editor drawing refactor in 2.91].
Now [in the spirit of T73182 / D11179], prevent using these where
unappropriate by using rna pointer polling functions.
Also add a security check for the 2D paint clone image crash in case a
stencil ImBuff cannot be provided for some reason, but generally old
files are now patched in do_versions_after_linking_300 (thx @brecht!).

The issue was caused by `textureSize()` returning the size of the level 0
even when the min texture level is higher than 0.
Using a uniform to pass the correct size fixes the issue.
This issue also affected the downsampling of radiance for reflections and
refractions.
This does not affect anything other than the recusive downsampling shaders.
This includes much improved GPU rendering performance, viewport interactivity,
new shadow catcher, revamped sampling settings, subsurface scattering anisotropy,
new GPU volume sampling, improved PMJ sampling pattern, and more.
Some features have also been removed or changed, breaking backwards compatibility.
Including the removal of the OpenCL backend, for which alternatives are under
development.

With this commit, curve objects support the geometry nodes modifier.
Curves objects now evaluate to `CurveEval` unless there was a previous
implicit conversion (tessellating modifiers, mesh modifiers, or the
settings in the curve "Geometry" panel). In the new code, curves are
only considered to be the wire edges-- any generated surface is a mesh
instead, stored in the evaluated geometry set.
The consolidation of concepts mentioned above allows remove a lot of
code that had to do with maintaining the `DispList` type temporarily
for modifiers and rendering. Instead, render engines see a separate
object for the mesh from the mesh geometry component, and when the
curve object evaluates to a curve, the `CurveEval` is always used for
drawing wire edges.
However, currently the `DispList` type is still maintained and used as
an intermediate step in implicit mesh conversion. In the future, more
uses of it could be changed to use `CurveEval` and `Mesh` instead.
This is mostly not changed behavior, it is just a formalization of
existing logic after recent fixes for 2.8 versions last year and two
years ago. Also, in the future more functionality can be converted
to nodes, removing cases of implicit conversions. For more discussion
on that topic, see T89676.
The `use_fill_deform` option is removed. It has not worked properly
since 2.62, and the choice for filling a curve before or after
deformation will work much better and be clearer with a node system.
Applying the geometry nodes modifier to generate a curve is not
implemented with this commit, so applying the modifier won't work
at all. This is a separate technical challenge, and should be solved
in a separate step.

This patch allows dropping material assets from material slot under the mouse
cursor. Before this change the material slot had to be hand-picked from the
properties panel.
For consistency it is chosen to do this in any shading mode as the tooltip shows
what is exactly going to happen during release.
The feature also works for other object types than Meshes as it uses the drawn surface on the
GPU to detect the material slots. Performance of this patch has been tested with AMD GCN3.0
cards and are very responsive.

Allow the UDIM grid to be shown and adjusted when there are images
loaded in UV edit mode. Right now the grid feature disappears once an
image is loaded and many have found this to be confusing.
Based on community and artist feedback, there was support to change this
behavior[1]
This patch does the following:
- Allows the grid to be shown even when images are present
- The max allowable dimensions for the grid has been increased from
10x10 to 10x100 to match the underlying maximum UDIM range that blender
supports
Note: This should not affect other Image editor modes like Paint/Mask or
the Render Result viewer etc. Future work in this area is currently
documented in a dedicated design task[2]

The idea is to only allocate pixel storage only when there is an actual
data to be written to them.
This moves the code forward a better support of high-res rendering when
pixel storage is not allocated until render engine is ready to provide
pixel data.
Is expected to be no functional changes for neither users no external
engines. The only difference is that the motion and depth passes will
be displayed as transparent for until render engine provides any tile
result (at which point the pixels will be allocated and initialized to
infinite depth).

selected pass
Caused by {rBebaa3fcedd23}.
Seems this above commit assumed an ImageUser's multi_index is only used
for Multiview/Stereo? This is not the case, multi_index also stores the
index for layer/pass combination.
If we call both BKE_image_multilayer_index and BKE_image_multiview_index
(even though this is not appropriate/needed for multilayer images?), we
might end up overwriting multi_index again.
note: looking at this I was also wondering why we update the ImageUser
in image-buffer-aquiring funnctions [and not from the UI, e.g.
template_image_layers, but that is a whole different story I guess, see
comment in T90772 as well]
note2: this could also use a utility function (this is not the only
place where this is done), this is fo a cleanup commit.

This was working differently in 2.79, tried tracking this down and it
seems this was wrong since the 2.8 beginning in {rB7907dfc40018}.
This would not only crash without an active scene camera, but would also
result in different tracks from different camera's constraints could not
be selected.
So select id depends on corresponding camera, remove the dependency on
scene camera completely.

Add Apply Constraint, Duplicate Constraint, and Copy To Selected
operators, and include them in a menu similar to the menu for modifiers.
The shortcuts in the extras menu are also matched to modifiers.
All the here added operators are intended to work exactly like the
analogous ones for modifiers. That means the apply operator should apply
a constraint as if it was first in the list, just like modifiers do. I
have added the same warning message as for modifiers when that happens.
The decision to use this approach of appling the constraint as if it was
first, was made for consistency with modifiers. People are already used
to how it works there. Is also provides more intricate control over the
applied transforms, then just applying all constraints up to that one.
Apply all constraints is already kinda implemented in Bake Animation.

This commit moves the storage of `bDeformGroup` and the active index
to `Mesh`, `Lattice`, and `bGPdata` instead of `Object`. Utility
functions are added to allow easy access to the vertex groups given
an object or an ID.
As explained in T88951, the list of vertex group names is currently
stored separately per object, even though vertex group data is stored
on the geometry. This tends to complicate code and cause bugs,
especially as geometry is created procedurally and tied less closely
to an object.
The "Copy Vertex Groups to Linked" operator is removed, since they
are stored on the geometry anyway.
This patch leaves the object-level python API for vertex groups in
place. Creating a geometry-level RNA API can be a separate step;
the changes in this commit are invasive enough as it is.
Note that opening a file saved in 3.0 in an earlier version means
the vertex groups will not be available.

Channel packed images should not have their RGB affected by alpha.
rendering in Cycles and Eevee was fine already, but displaying these was
not right in the Image and Node editors.
Not 100% sure what to do for the "Color and Alpha" mode, but I guess
this should stay like it was before (applying the alpha).
"Color", "R", "G", and "B" modes were changed to not have color be
affected by alpha though.
