Fix: Sequencer backdrop not updated during playback.

Caused by recent optimization in {7b76a160a4}.

BMesh: assert that face normals have been updated for tessellation

This catches missing normal updates that may cause invalid tessellation.

Cleanup: remove return value from face normal calculation

This value is always 'sides - 2', no need to return this value.

Fix missing normal update in edit-mesh blend-from shape operator

BMesh: use faster normal update method for edit-mesh coordinates

This wasn't included in the previous fix so it'd be 2.93 compatible.

Fix outdated face tessellation use when editing edit-mesh coodinates

Screen: clear runtime structures on file-read & data-copy

Clear the runtime data structs instead of individual members,
this simplifies adding new runtime members as there are at least
two places they would need to be cleared.

Resolves error in D8883.

Cleanup: correct incomplete comment

Fix image space missing mask display panel

Cleanup: unused argument & variable warnings

Cleanup: remove "_" prefix for used arguments

Cleanup: use private methods for internal operator utilities

Also remove unused argument.

Cleanup: use doxygen comments for DNA_color_types

Also use enum instead of defines for Scopes.wavefrm_mode

Win8 cleanup, remove dead function pointer and macro.

Geometry Nodes: Join dynamic curve attributes in the join geometry node

This commit lets the join geometry node transfer dynamic attributes
to the result, the same way that point cloud and mesh attributes are
joined. The implementation is different though, because of an
optimization implemented for curves to avoid copying splines.

The result attribute is added with the highest priority domain (points
over splines), and the highest complexity data type. If one curve had
the attribute on the spline domain but not others, the point domain
values will be used.

Generally this is a bit lower level than I would have liked this code
to be, but should be efficient, and it's really not too complicated.

Geometry Nodes: Parallelize curve reverse node

Each spline can be handled separately here. This gives approximately a
2x speedup on my 8 core processor on an input of 80000 2 point splines.

Cleanup: Refactor join geometry node attribute gathering

Instead of building a set and then determining the final domain and
type for every attribute separately in the loop, construct a map with
the necessary data in the first place. This is simpler and should be
slightly more efficient.

Geometry Nodes: Curve Reverse Node

This is an implementation of T88722. It accepts a curve object and
for each spline, reverses the order of the points and all attributes.
This is more of a foundational node to support other nodes in the
future (like curve deform)

Selection takes spline domain attributes to determine which splines
are selected. If no selection is present all splines are reversed.

Geometry Nodes: Curve to Points Node for Evaluated Data

This node implements the second option of T87429, creating points
along the input splines with the necessary evaluated information
for instancing: `tangent`, `normal`, and `rotation` attributes.
All generic curve point and spline attributes are copied to the
result points as well.

The "Count" and "Length" methods are just like the current options
in the resample node, but the output is points instead of a curve.
The "Evaluated" method uses the points you see on the curve directly,
and therefore should be the fastest.

The rotation data is retrieved from a transform matrix built with the
same method that the curve to mesh node uses. The radius attribute is
divided by 10 so the points don't look absurdly huge in the viewport.
In the future that could be an option.

For the implementation, one thing that could use an improvement
is the amount of temporary allocations while resampling to evaluated
points before the final points. I expect that reusing a buffer for
each thread would give a nice improvement.
