The projection was transformed by the object transform, but it's meant
to be in camera space, not affected by the camera view transform or by
the local object's transform. This fix makes viewport raycasting use
cases work without a manual fix in nodes.

Currently the node tool operator stores the mouse position from
the first execution because it's not possible to retrieve it again from
the operator redo callback which doesn't have access to the event.
However, other inputs like the region size and the viewport transform
are retrieved again for every redo execution. This creates inconsistency
and generally makes redo less useful for node tools than it should be.
Generally tweaking an input in the redo panel should keep everything
else the same.
This commit adds the rest of the inputs as RNA properties just like
how mouse position is already handled.

This allows the draw tool to temporarily enable the eraser.
Adds a new `BrushStrokeMode` called `BRUSH_STROKE_ERASE`.
This is used by the keymap to enable erasing while using
the draw tool with CTRL.

Interpolation tool for strokes ported from GPv2.
Adds a new operator that inserts a new frame with interpolated curves.
The source curves are taken from the previous/next keyframe.

Previously the spans would be drawn even if you had slid the retiming
keys out of bounds of the strip margins, leading to them being drawn out
side of the strip.

Updates the slide operator to be able to do subframe adjustments of
audio strips. If you hold shift while sliding (the S shortcut), it will
start to do subframe adjustments. It is also possible to type in
fractional inputs while in modal mode. (IE start sliding then type 1.5)
Regular sound offsets (based on VSE strip offset) only worked with
negative values even if the waveform was draw correctly. Fix so positive
frame offsets does the correct thing.
The vector pass and potentially other vectors that store 4 values are
stored wrongly, in particular, the last channel is ignored. To fix this
we identify if a vector pass is 4D and store the information in the
result meta data, then use this information to either save a 3D or a 4D
pass in the File Output node.
This is a CPU implementation of the same mechanism in the GPU compositor
implemented in 57a6832b17. The CPU implementation is a bit more complex
because the CPU compositors stores 4D vectors in color images internally
which can lead to information loss in case of implicit conversion when
the File Output has vector sockets. So what we do is force all vector
inputs to the File Output operation to be color, then save that as 3D or
4D depending on the meta data as well as the original UI socket type.

The array-length of a texture view isn't stored at the same location as
the array-base and was forgotten that it was a feature what had to be
supported.
Detected when testing `monster.blend` where the SSS object id wasn't
set and lead to missing materials.

When using a python expression, its execution is disabled by
default unless specified differently in the user preferences.
Previously this only produced the error
"Error: Invalid Python expression". However that isn't really the correct error.
Now the error reads "Python restricted for security".
I've added a new flag to the driver `DRIVER_FLAG_PYTHON_BLOCKED` that is set
if the driver can't run because python is blocked

When quickly running the "frame step" and "insert key" operators it was possible to
run the key insertion when the depsgraph hasn't yet been updated.
Because the key insertion code took the frame from the scene, but the channel values
from the depsgraph, the inserted keys were appearing to be duplicated from a different frame.
The fix is to ensure an evaluated depsgraph is used, so the correct values are placed
at the correct time.

Add the concept of 'active slot' within an Action. This allows
clicking on a slot in the Action editor, to select it and mark it as
'active'.
Note that this does _not_ add support for action slots in
`ANIM_set_active_channel()`, as that function doesn't get enough info
to do that, and refactoring it is not on my wishlist.
RNA property `action.slots.active` can be used to access and set the
active slot in Python. `slot.active` can be used to query the slot's
active state, and is read-only (so that there is one way to set the
active slot).
A panel in the Action editor shows info about the active slot. This
panel is just a minimal UI that shows the name and an icon
representing the idtype of the active slot.

This implements the _automerge_ feature which finds nearby end points
during stroke draw and merges the new curve with existing strokes.
New utility functions are added in `geometry` for slightly generalized
functionality. The `curves_merge_endpoints` takes an index map that
describes how to connect curves by index. It performs a topological sort
and reorders connected curves into contiguous ranges. This can be used
with an arbitrary number of connected curves. The tool feature itself
only uses a single curve, based on 2D end point positions.
Unit tests have been added for the curve merge utility function.

The (GPv2) fill tool has an "extension" mode to assist with filling
small gaps where strokes don't fully meet.
- Overlay: Draws various helpers during modal fill tool operation, using
the same functions as the render-to-image used for applying the fill
tool.
- Extension lines: Scrolling or page up/down extends the tips of strokes
and draws extra boundary lines to limit filling.
- Extension circles: Press S to toggle the mode. This draws circles
around stroke tips.
- Stroke overlay: This can be enabled in the brush settings
(_Advanced > Visual Aids_) to draw strokes in a simple color on top of
the viewport.
- Extension line collision: Tests for intersections of extension lines
with other lines and with strokes, and cuts them short. Enable in
brush settings (_Advanced > Strokes Collision_).
- Better defaults for extension increments: The values are in Blender
units, and quite arbitrary. Using lower values makes it feel more like
GPv2 in the 2D animation template.
- Draw functions in the `ed::greasepencil::image_render` namespace now
consistently expect coordinates in view space (avoids confusion and
works better for 2D elements).
- Some internal renaming and cleanup (many variable names come from GPv2
and were not very clear).

Both the Follow Curve constraint and parenting with the follow curve option
require a property on the Curve ID to be animated if the user wants the
follower object to animate along the curve. However, the fcurve for this
was always getting created as a legacy action fcurve, regardless of whether
the action was actually legacy or not. If the action was layered, this
resulted in the follower object not animating along the path.
The underlying issue was that the code that created the fcurve was using
`action_fcurve_ensure()`, which hadn't yet been updated to work correctly with
layered actions, and thus the fcurve was created as if the action was legacy.
This commit fixes that by updating `action_fcurve_ensure()` to work with
Baklava phase-1 layered actions in limited circumstances, and also
ensuring that the follow curve code passes an appropriate ID RNA pointer
(required to find/create an appropriate Slot).

The `resolution` and `nurbs_order` attributes of curves are expected to be `>=
1`. Due to a bug, it was possible that they are initialized to zero: #124534.
This fix adds versioning code to fix the curves that have been written
incorrectly.

Previously, it was fairly easy to create built-in attributes which have invalid
values, because attributes were generally zero-initialized. This was especially
problematic for attributes that had certain invariants that Blender relies on
and that should never be zero. For example, the curve resolution should always
be at least 1.
To reproduce the issue, add the `resolution` attribute from the attributes panel
to curves. They had a value of 0 by default. I found this while investigating
#124416.

Shortcut and quick favorite operators wouldn't show up in the regular asset
shelf. In the popup the shortcut operators would but they crashed with use
after frees.
Basic issue is that activating view-items by applying the button didn't work
well. That messes with button storage, but also the operator data (like
`uiBut.optype`) is unset after applying, in this case before the context menu
was built.
Instead, activate the view-item directly, and call the activate operator in its
`on_activate()` callback. The button shouldn't call this operator again, so
added a way to attach operators to buttons without calling them.
Seems generally useful to be able to attach an operator to buttons for
tooltips, "Assign Shortcut" and the like, without it being called on button
apply.

This change simplifies access to this state by prefetching code.
Previously it had to iterate over screens from `bMain` in code local to
prefetching. Now this state is available to other code in VSE.
In preparation for the topology relax brush which shares much of this
code, this commit renames the file and distinguishes between methods
that will and will not be shared between the topology relax and face set
relax brushes.
