This makes it work again at least for the non-UDIM case. For UDIM it's not
great still but I'll consider that a known limitation. A proper solution is
probably to find the closest tile at the start of the stroke and then only
paint in that one tile for the rest of the stroke.
Caused by the introduction of UDIM (rBc30d6571bb47).
We need to make sure the tiles ImageUser is set up correctly [especially
the framenr], otherwise BKE_image_acquire_ibuf() and friends will fail
to find the correct ImBuf.
Also instead of initializing a minimal BKE_imageuser_default, now use
an appropriate ImageUser if avaliable and pass this around (instead of
just the tile_number). 2D painting can reuse the Image Editor ImageUser,
for 3D painting we still rely on a default ImageUser in most places, but
at least set the framenr correctly].
This also fixes crashes when doing image operations such as inverting or
resizing on images in a sequence in the Image Editor.
This also fixes color sampling (S) from the 3DView going wrong for image
sequences (would fallback to OpenGL sampling because an ImBuf could not
be found).

The code was using brush->alpha directly, so the alpha value from
UnifiedPaintSettings was not used when eneabled.

This was caused by a call to paint_2d_bucket_fill that I missed in the
UDIM changes.
Now, this feature does not only not crash, but it even works with tiled
images!
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!

The AA offset should be substracted, not added. I think this was
introduced when I refactored the code in a code review.

You may want to disable antialiasing if you are working with pixel art
or low resolution textures. It is enabled by default.

This commit enables antialiasing in 2D painting.
It also includes some fixes related to line drawing in the stroke spacing code.

This is often invalid, outdated or misleading

It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
- Undo that changes modes currently asserts,
since undo is now screen data.
Most likely we will change how object mode and workspaces work
since it's not practical/maintainable at the moment.
- Removed view_layer from particle settings
(wasn't needed and complicated undo).
- Use a single undo history for all operations.
- UndoType's are registered and poll the context to check if they
should be used when performing an undo push.
- Mode switching is used to ensure the state is correct before
undo data is restored.
- Some undo types accumulate changes (image & text editing)
others store the state multiple times (with de-duplication).
This is supported by checking UndoStack.mode `ACCUMULATE` / `STORE`.
- Each undo step stores ID datablocks they use with utilities to help
manage restoring correct ID's.
Needed since global undo is now mixed with other modes undo.
- Currently performs each undo step when going up/down history
Previously this wasn't done, making history fail in some cases.
This can be optimized to skip some combinations of undo steps.
grease-pencil is an exception which has not been updated
since it integrates undo into the draw-session.

Now all the fine-tuning is happening using parallel range settings structure,
which avoid passing long lists of arguments, allows extend fine-tuning further,
avoid having lots of various functions which basically does the same thing.
