This allows building tools that simplify Blender core development.
The depsgraph already exposed the dot graph using the `debug_relations_graphviz`
method. This has been extended to return the data as a string. The filepath is
optional now.
Similar functions have been added for node trees. Note that these should be used
on evaluated node trees.
Add a new function to the draw manager to only
issue a unique resource ID per `ObjectRef`.
This avoids the memory overhead of duplicating
the handle for each overlay.
The handle is stored inside the `ObjectRef` on
first query.
Rel #102179
Fixes Grid2D tiles background and boundaries drawing.
To reproduce switch to mesh edit mode and in UV editing view overlay
options set `Tiles X` or `Y` to more than 1.

Also remove noisy print when a thumbnail can't be generated from an
animation. Similar prints have been commented and mainly seem useful
for debugging.
On MS-Windows the current frames file set the window title.
Remove this because it's strange to have the title flickering over
each name and the animation player already supports showing the filename
inside the window.
Avoid setting default cursor while number dragging. But always reset
cursor in title area if even there is a button in that space. Decrease
the title height slightly to work with title-less popups.

Replace the `PBVH_UpdateBB` flag with a separate vector of booleans.
The simplest impact of this is that we can tell when there are no changed
nodes in constant time. Besides that, it also works better with the recent
IndexMask usage for selections of nodes, and allows better const
correctness too, since nodes themselves don't have to be changed
when positions are changed. This also leads into plans to change PBVH
draw data tagging to avoid having to reupload all attributes when only
one changes.
Part of #118145.

Avoid truncation errors causing unneccessary resizing by passing floats
to UI_block_translate. That function translates block and button rects
which are floats.

When inserting keys, look on related IDs for an action to reuse that.
This will make use of the slot system on the new layered action to ensure
the animation data doesn't collide.
This is done on the `id_action_ensure` function since that is the common
function to get an action off an `ID`.
IDs with more than 1 user will be skipped.
"Related ID" in this case is hardcoded with a `switch` statement for each ID type.
The system builds a list starting from the ID that should be keyed and
keeps expanding the list until an action is found or no more
non-duplicate IDs can be added. (This is using linear search for duplicate checks,
but I don't think we will deal with a lot of IDs in this case)

This PR implements the Normalize operators in Weight Paint mode for
GPv3:
- Normalize weights of the active vertex group. This operator normalizes
all the vertex weights in the active vertex group to a value between 0.0
and 1.0.
- Normalize All. This operator normalizes the weights of all vertex
groups, so that for each vertex, the sum of the weights is 1.0. Weights
of locked vertex groups are not changed. By default, the active vertex
group also stays unchanged, unless it's necessary to reach a normalized
state.
The operators are added to the 'Weight' menu in Weight Paint mode.

This rename the `Cutter` tool's name, code and icon to `Trim`.
The legacy Grease Pencil code is unchanged.
This was discussed in the 2024-07-30 Grease Pencil Module Meeting.
Reasons for the change:
- Match the `Trim Stroke Ends` setting on brushes.
- Match the `stroke_trim` operator.
- Name is more clear and more commonly used.
- Frees the name for a future boolean cutting tool.

This adds the following operators:
* Set Vertex Color
* Reset Vertex Colors
* Invert
* Brightness/Contrast
* HSV
* Levels
Also populates the `Paint` menu with them in vertex paint mode.

When syncing the NLA strip length with the Action it uses, use the
length of the assigned action slot. Previously the entire Action was
considered when determining the length.

Move the following BKE functions to the `animrig::Action` class. Some of
those will be extended to support slots in a future commit; for now they
still operate on all F-Curves in the Action.
| Old | New |
|---------------------------------|-------------------------------------|
| `BKE_action_frame_range_calc()` | `Action::get_frame_range_of_keys()` |
| `BKE_action_frame_range_get()` | `Action::get_frame_range()` |
| `BKE_action_has_motion()` | `Action::has_keyframes()` |
| `BKE_action_has_single_frame()` | `Action::has_single_frame()` |
| `BKE_action_is_cyclic()` | `Action::is_cyclic()` |
Implementations have been copied from the BKE functions. The frame range
functions now return `float2` instead of requiring two `float *r_…`
return parameters.
The `has_motion` function is now renamed to `has_keyframes`, as that is
what the implementation was actually testing for.
The functions now no longer are null-safe. The BKE functions handled a
null action pointer, but IMO that doesn't make sense, and in none of the
call sites I could find where this would actually be valid.
No functional changes.

Disable dynamic SDL loading as well as disable SDL for release builds.
This was only used for audio output which can already use OpenAL
if there are back-ends not natively supported by Blender.
- Remove extern/sdlew/
- Remove the WITH_SDL_DYNLOAD build option.
- Remove `bpy.app.sdl.available`.

Support suppressing "info" messages when running Blender.
Useful when Blender is used as part of an automated action
that should only show output for warnings/errors.
Ref !127562
Duplicating an Action stashes the original one on the NLA. The NLA
evaluation code didn't properly handle the special case of an all-muted
NLA (all stashed actions are muted there) when a layered Action was
assigned directly to the animated ID.
The code is now refactored to remove this special handling from the
`animsys_calculate_nla()` function. Instead it now just returns whether it
did anything. The caller can then decide to evaluate the main Action
instead. This ensures that there is only one "evaluate the main Action"
branch in the `BKE_animsys_evaluate_animdata()` function.

The bug was introduced in #126291, which was a refactor PR. Prior to the
PR there was a condition that could only trigger when a given pointer
was null. That pointer was turned into a reference in the refactor,
but instead of deleting the conditional code that should no longer be
reachable, the refactor simply removed the null check, allowing the code
to still trigger based on just the remaining part of the condition.
The code behind the condition bailed out before checking all fcurves for
whether they should be included in pose slide, and thus would omit some
channels from the breakdowner (and presumably other operators as well).
This commit fixes the issue by simple removing that code entirely, since
it's no longer relevant. It also renames the function and one of its
parameters to be clearer about what it actuallys does, since that was
pretty obscure before.

Add support for slotted Actions to the NLA evaluation code.
This also affects the pose library code and the Action Constraint. These
both share some Action evaluation logic with the NLA. They now
explicitly looks at only the first Action slot. The Action Constraint will
have to be updated to have an explicit slot selector, but that's for another
commit.
Pull Request: https://projects.blender.org/blender/blender/pulls/127425
Refactor to prepare for slotted action support to the evaluation of
quaternion F-Curves.
Since slotted Actions store F-Curves in an array, you cannot iterate over
them any more via the `ListBase` pointer `fcurve.next`. Quaternion
evaluation code has been refactored to work on a span of F-Curves instead
of just getting the first one.
For now, slotted Actions just evaluate their first slot only. A future
commit will add a slot handle parameter to evaluate the correct slot.
