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!

Custom render passes are added in the Shader AOVs panel in the view layer
settings, with a name and data type. In shader nodes, an AOV Output node
is then used to output either a value or color to the pass.
Arbitrary names can be used for these passes, as long as they don't conflict
with built-in passes that are enabled. The AOV Output node can be used in both
material and world shader nodes.
Implemented by Lukas, with tweaks by Brecht.

Issue likely caused by 8b31f6fb21.
With this, initializing the toolsystem (e.g. for a new workspace-scene
combination) would skip the entire create->initialize routine for
image/texture painting settings. Reason being that these are not
allocated, unlike other paint settings. So while correctly skipping the
create part, it also skipped the initialization, which was still needed.
This does further changes in related code to avoid NULL pointer
accesses.
This can be used to make closed surfaces behave more like a soft body.

This is only supposed to happen when copying nodes that are part of the user
editable database, not temporary copies for the dependency graph.
The LIB_ID_COPY_LOCALIZE test was wrong because it is a combination of multiple
bitflags as pointed out by Bastien, and was actually redundant anyway since
LIB_ID_CREATE_NO_MAIN is part of it.
Multisample buffers were used for smooth line drawing. As we now have
an algorithm that doesn't need the multisample buffers we can remove
them.
The user preference for viewport multi_sampling is replaced by single
toggle overlay `use_overlay_smooth_wire`. By default this setting is
enabled as the new drawing is really quick (<1ms) and uses zero hacks.

Rigify uses a property group to contain options of its rigs, so
currently it is impossible to use Alt-Click or Copy To Selected
to change a setting for multiple rigs at the same time.
The main problem here is that there is no efficient way to find
which bone the property group belongs to. To maintain performance,
implement this by checking the active bone if it is known. Copy
Data Path and related features still don't work, as data path
calculation can't use context.

Now when change the setting the strokes are recalculated.
To do this, it was necessary to move the UV recalc to BKE module in order to share with Draw Engine. If the recalc it was done in draw engine, the factor was only calculated for evaluated version and there was a problem when draw a new sytroke.
Now, the RNA parameter recalc the original datablock instead of tag for be calculated in Draw Engine.
This is a revert of a small fraction of commit rB5e332fd700
that introduced the issue according to bisect.
Doing a break here is wrong, because BKE_crazyspace_build_sculpt
assumes that processing stopped at the first deform modifier
without deformMatrices, and thus skips all modifiers until it
finds one like that. Thus this early loop exit makes the behavior
worse, as instead of skipping just Mask and Mirror, it skips all.
Loading a blendfile allocates one or more windows that need to be freed.
Freeing those windows also calls `BKE_workspace_instance_hook_free()` to
free workspaces. However, in the `BlendfileLoadingBaseTest` test there are
no workspaces allocated. This caused an assertion failure, which was worked
around by not asserting when Blender is running in background mode.

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.
The relation between the pressure/size and the pressure/alpha is a
fundamental property that defines the behavior of a brush, so it does
not make sense to have it unified across all brushes. This applies both
for sculpting and painting.
Some of the new 2.82 brushes need pressure/size or pressure/alpha to be
enabled to work propely, while others don't. Users should not be
switching on and off this property manually when changing brushes if they
want to use unified size. This is also causing that some users are using
the brushes with an incorrect configuration.

Extend options are currently stored per curve. This was not clearly

This change will move the option from `Curve` to `CurveMapping`. In
order to support this the API had to be changed.
BPY: CurveMap.evaluate is also moved to CurveMapping.evaluate what
breaks Python API. Cycles has been updated but other add-ons have
not. After release of 2.81 we can merge this to master and adapt

This function exposes the already-existing static `object_moves_in_time()`
function, and optionally recursively checks the parent object for
animatedness as well.
I also added checking `AnimData::overrides` to
`BKE_animdata_id_is_animated()`. This ensures that, apart from the optional
recursion to the parent object, the function has the same functionality.
Instead of always writing the transform on every frame, it's now checked
whether the object is animated at all. This could be made stricter to
reduce false positives, for example by checking FCurves and drivers to
see whether translation/rotation/scale is animated. However, this
approach is already better than the `return true` we had before.
This commit adds the BKE_animdata_id_is_animated(id) function, which
returns true if the ID datablock has non-empty animation data. This is
determined by checking the the active action's fcurves, the drivers, and
NLA tracks.
The function isn't used anywhere, and it's deceptively returning false
negatives. For example, `modifier_dependsOnTime()` will return `false`
for hook modifiers, even when the hook target is animated. Querying the
depsgraph for dependency on the time source would be a better approach.
The `modifiers_getVirtualModifierList()` function previously took a non-
const `Object *ob` parameter, preventing it from being called from more
restrictive functions. Since the function doesn't modify the passed
object, it could easily be made const.
No functional changes.
This implements a 5th-order equation smoothstep, which produces a flat
surface at the brush center. Some users find that our current grab brush
is too sharp, so now we have both options.
This also improves the behavior of the new clay brushes.

When introducing "drag-all-selected" support all over Blender, we
figured this wouldn't work well with the Graph Editor
selection/transform behavior.
Hence, William and I worked on the following changes, although we used
this chance to improve the behavior in general too.
For more info see T70634.
* Handles now always move with the key, regardless if they are selected
or not.
* Selecting the key doesn't select the handles anymore, their selection
is separate.
* Multiple keys and handles can now be dragged.
* Dragging a handle moves all selected handles **on the same side**.
* Tweak-dragging any handle can never affect any keyframe location,
only handles.
* G/R/S should behave as before.
* Changing the handle type with a key selected always applies the change
to both handles.
* Box selection with Ctrl+Drag now allows deselecting handles (used to
act on entire triple only).
* Box selection //Include Handles// option now only acts on visible
handles, wasn't the case with Only Selected Keyframes Handles enabled.
* Box selection //Include Handles// is now enabled by default in all
bundled keymaps.
The changes have been tested for some days by the animators here in the
Blender Animation Studio. Some changes are based on their feedback.
Also, this improves/adds comments for related code.

After adding normal radius, the main use of the Scrape brush is to create flat surfaces with sharp edges. In that case, it does not make sense to have our current "Peaks" version of the brush as its inverted version.
The correct inverted version of Scrape for this use case is the Fill brush. This way you can use this tool to crease both concave and convex sharp edges and to fix the artifacts one version produces with its inverted version.
I think we should merge these two tools into one, but for now, this solution keeps compatibility with the old behavior.

These tools are designed to move the topology on top of the mesh without affecting the volume.

This operator is similar to Mask Extract, but it deletes the masked points on the original mesh and fills the holes. This can be useful for quickly trimming or splitting an object.

The Multiplane Scrape brush creates sharp edges with a given fixed angle by trimming the mesh with two planes in local space at the same time. When working with stylized or hard surface models, this brush produces way better results and is more predictable than any other crease/flatten brush based on curves and alphas.
It is also the first brush we have than can produce hard surface concave creases.
The Multiplane Scrape Brush also has a dynamic mode where it samples the surface to fit the angle and scrape planes during a stroke. With this mode enabled you can sculpt multiple times over the same edge without creating artifacts.
It can also create creases that change between concave and convex during the same stroke.
The behavior of this brush will improve after merging patches like D5993 and its behavior in concave creases can still be improved, so I will keep tweaking its parameters and default values once we have all brush properties available.
