This patch contains the work that I did during my week at the Code Quest - adding support for tiled images to Blender.
With this patch, images now contain a list of tiles. By default, this just contains one tile, but if the source type is set to Tiled, the user can add additional tiles. When acquiring an ImBuf, the tile to be loaded is specified in the ImageUser.
Therefore, code that is not yet aware of tiles will just access the default tile as usual.
The filenames of the additional tiles are derived from the original filename according to the UDIM naming scheme - the filename contains an index that is calculated as (1001 + 10*<y coordinate of the tile> + <x coordinate of the tile>), where the x coordinate never goes above 9.
Internally, the various tiles are stored in a cache just like sequences. When acquired for the first time, the code will try to load the corresponding file from disk. Alternatively, a new operator can be used to initialize the tile similar to the New Image operator.
The following features are supported so far:
- Automatic detection and loading of all tiles when opening the first tile (1001)
- Saving all tiles
- Adding and removing tiles
- Filling tiles with generated images
- Drawing all tiles in the Image Editor
- Viewing a tiled grid even if no image is selected
- Rendering tiled images in Eevee
- Rendering tiled images in Cycles (in SVM mode)
- Automatically skipping loading of unused tiles in Cycles
- 2D texture painting (also across tiles)
- 3D texture painting (also across tiles, only limitation: individual faces can not cross tile borders)
- Assigning custom labels to individual tiles (drawn in the Image Editor instead of the ID)
- Different resolutions between tiles
There still are some missing features that will be added later (see T72390):
- Workbench engine support
- Packing/Unpacking support
- Baking support
- Cycles OSL support
- many other Blender features that rely on images
Thanks to Brecht for the review and to all who tested the intermediate versions!

This was an old bug which could be caused by saving after separating.
Changes from 79b703bb63 made this fail reliably.
Update shape key indices when they may be used again later.
Previously these used a gizmo to redo the operator however this
complicated having on-screen gizmos to access tools (see T66304).
Replace this with a generic way to make an operator that only has an
execute function into a modal operator.
This is used for smooth and randomize tools.
Unlike operator gestures, this handles storing and resetting the data.
Currently this only handles edit-mode data, however it's can be
extended to other kinds of data.
2.79 also did this [select the new instances] which was useful.
2.79 also kept the instancer selected [this patch deselects]

This introduces object mode tagging for data which hasn't yet been
written back to the ID data.
Now when selecting other sculpt objects, the original objects data is
flushed back to the ID before writing a memfile undo step.

Note: done in a separated commit to keep track of changes done not directly related to bug reported in T69459.
Users now can turn on in a viewport collections that are temporarily
hidden (eye) in the view layer.
Design task: T61327
As for the implementation, I had to decouple the visibility in the
depsgraph from the visibility in the view layer.
Also there is a "bug" that in a way was there before which is some
operators (e.g., writing a text inside of a text object, tab into edit
mode) run regardless of the visibility of the active object. The bug was
present already (with object type visibility restriction) in 2.80 so if
we decide to tackle it, can be done separately (I have a patch for it
though P1132).

This should fix most of the shrinkwrap artifacts when the preserve volume option is active. After this commit the default voxel remehser settings should not fail in the default cube.

Quadriflow does not support non manifold meshes. (Edges with > 3
connected faces and discontinuous face normal directions)
While it does sometimes "work" in these configurations, the results are
not good and in most cases it just flat out will crash.
Added a sanity check to make sure that the input mesh is manifold.

The core of the issue here is that 'make single user' functions still
does its own, manual and quite partial, remapping of IDs, which covers
all most common cases but cannot consider *all* possible ID usages
(especially when it comes to drivers or custom properties, that can
essentially point to any kind of data-blocks).
This fix is merely a band-aid, there is no way to fully solve this
without a complete rewrite of that area of code to make use of modern ID
management code.
This commit enables OpenVDB adaptivity in the voxel remesher. It can be useful to reduce the polygon count if you want to switch to dyntopo after using the voxel remesher workflow.

This patch adds paint symmetry support to Quadriflow. It bisects and mirrors the input and the output from the remesher to build the final mesh using the preserve boundary option.
This is also an important performance improvement in Quadriflow because it only needs to process half of the mesh with half the resolution.

This commit fixes most of the issues we currently have in the voxel remesher. Mesh volume is preserved when doing multiple iterations, so the sculpt won't shrink and smooth each time you run the remesher. Mesh topology is much better, fixing most issues related to mask extraction and other topology based operations.

Previously the cache for the modifier would not be invalidated if
modifier settings were changed with drivers or keyframes.
Now we compare the current setting with the ones used to generate the
cache and invalidate the cache if they differ.

This change makes it so motion paths are using minimal possible
dependency graph which is sufficient to evaluate required motion
path targets.
Disclaimer: granularity is done on ID level, but it is possible
to go more granular if really needed.
Brings time down to 0.5 sec when updating motion path for the
Rain animation file used for benchmarks in the previous commits.

Particularly noticeable when vertex painting with a subsurf modifier.
In some cases every sculpt or paint stroke step would evaluate the dependency
graph. This should only happen for redraws. Now more selectively choose if the
dependency graph should be evaluated to initialize the view context. Doing it
in the view context evaluation is somewhat hidden, now it's more explicit.

The active object can be `NULL`, which causes a segfault in
`BKE_object_is_in_editmode(NULL)` (and if that were made NULL-safe, the
segfault would happen further down in `object_remesh_poll()`).
Make a distinction between flush sculpt changes for rendering, and forcing
sculpt data structures to be rebuilt after mesh changes. Also don't use PBVH
for renders.
That's exactly why we should get rid of all those 'custom cases'
remapping code, it's hard enough to keep a single place
(library_query.c) up to date and 100% valid, but having more areas doing
their own remapping is just impossible to maintain... Some day...
Support per-viewport collection visibility options.
Note 1: There is no way to show a collection that was not visible before
due to depsgraph. Otherwise we would risk having all the collections in
the depsgraph and I believe this is not the idea.
An alternative would be to have a new depsgraph for viewports that are
not local. Something to keep in mind if we do per-viewport current frame
in the future.
So for now what we do is to only allow collections visibility to be
disabled/hidden in this mode.
Note 2: hide_viewport (the eye icon) doesn't really matter for
depsgraph. So after the merge we can still ignore it to show the
collections locally in a viewport with no problems for the depsgraph.
