The armature reported had two bones with a `bMotionPath` but its lengths
are zero (which causes trouble in `motion_path_cache` drawing code due
to 0 allocations).
Not exactly sure how we got there, something like
`animviz_verify_motionpaths` should take care of this already in current
code, but this might be from a time where there were not enough sanity
checks.
So now early out in `motion_path_cache` if we encounter such a
"corrupted" motion path.

Currently, we don't support this. Depending on the geometry type, the rotations
are either displayed as black, magenta or there is a crash. Better disable this for
now until we have a proper implementation. It's not quite obvious how rotation
values should be converted to a color, so this also needs some design work.

Performing an off-screen draw call while drawing the viewport isn't
supported, add a check that raises an exception when called from Python
instead of crashing.
Ref: !118780
The issue described was that the motion path didn't display the last frame
of a scene.
This PR makes the user facing motion path range inclusive on both ends.
E.g. when the user specifies a motion path from 1-24 the will now get all 24
frames, whereas previously the motion path would end at frame 23.
This also makes the `Scene Frame Range` option work properly since that
had the same issue. Now it displays the actual full scene range.
Internally, the `bMotionPath` is still exclusive on the upper bound.
It is just the `bAnimVizSettings` range that has been modified.

When the retopology overlay is enabled, the edit mesh is not drawn
in solid mode. When you disabled overlays however, it would not be
drawn in any mode, which understandably confused users.
Now it checks whether overlays are enabled before it hides the solid mesh.

The compositor assumes the entire viewport as its compositing space even
in camera view. The current design decision was to limit the compositing
space by the camera region only if the camera passepartout is opaque,
that is, areas outside of the camera are not visible.
This patch changes that behavior to always limit the compositing space
by the camera region. The downside is that areas outside of the camera
will be left uncomposited.
This is useful to match viewport compositing to final render compositing
in terms of maintaining the same space, but not necessarily the same
resolution. However, this still has the limitation that space will be
different when the camera region intersects the viewport, since we only
composite their intersection in that case.

The `object_to_world` and `world_to_object` matrices are set during
depsgraph evaluation, calculated from the object's animated location,
rotation, scale, parenting, and constraints. It's confusing and
unnecessary to store them with the original data in DNA.
This commit moves them to `ObjectRuntime` and moves the matrices to
use the C++ `float4x4` type, giving the potential for simplified code
using the C++ abstractions. The matrices are accessible with functions
on `Object` directly since they are used so commonly. Though for write
access, directly using the runtime struct is necessary.
The inverse `world_to_object` matrix is often calculated before it's
used, even though it's calculated as part of depsgraph evaluation.
Long term we might not want to store this in `ObjectRuntime` at all,
and just calculate it on demand. Or at least we should remove the
redundant calculations. That should be done separately though.

Implements the design from #116067.
The socket type is called "Matrix" but it is often referred to as "Transform"
when that's what it is semantically. The attribute type is "4x4 Matrix" since
that's a lower level choice. Currently matrix sockets are always passed
around internally as `float4x4`, but that can be optimized in the future
when smaller types would give the same behavior.
A new "Matrix" utilities category has the following set of initial nodes"
- **Combine Transform**
- **Separate Transform**
- **Multiply Matrices**
- **Transform Direction**
- **Transform Vector**
- **Invert Matrix**
- **Transpose Matrix**
The nodes and socket type are behind an experimental flag for now,
which will give us time to make sure it's the right set of initial nodes.
The viewer node overlay doesn't support matrices-- they aren't supported
for rendering in general. They also aren't supported in the modifier interface
currently. But they are supported in the spreadsheet, where the value is
displayed in a tooltip.

This PR prepares GPv3 for calculating falloff factors when working in multi frame editing mode.
The falloff popover is added to the UI.
A `float multi_frame_falloff` is added to `MutableDrawingInfo`. This is a factor from 0.0 to 1.0f.
A `retrieve_editable_drawings_with_falloff()` is added to the utility functions, which retrieves the falloff factor for each drawing when
multi frame falloff is enabled.
To avoid a copy, the return type of `retrieve_editable_drawings()` and friends is changed from
`Array<MutableDrawingInfo>` to `Vector<MutableDrawingInfo>`.

The benefits are removing unnecessary reallocations of the string data
and unnecessary recalculations of the size, better type safety, and more
automatic memory management.
