Cleanup: correct/clarify PlayAnim comments

LineArt: better ui logic for crease threshold.

LineArt: Filtering feature line using face mark.

USD import: remove unused code.

Removed unused mesh sequence modifier enums
and unused velocity scale parameters in the
mesh reading function declarations.

LineArt: Fix LRT_ITER_ALL_LINES_BEGIN.

This handles when the first line list being empty.

LineArt: Custom UI for adding GP object.

This allows extra options (in-front and stroke order) to be shown when adding line art kind of grease pencil object.

Fix: Curve resample duplicates last point for cyclic splines

The last point of the output was at the same location as the
first point of a cyclic spline. The fix is simple, just account for
the cyclic when choosing the sample edge length, and don't
hard code the last sample.

Fix T88126: Curve resample crash for single point input

The spline `length` function assumed that the curve always had evaluated
edges. That is clearly false. This commit adds a check to `length` and a
special case for a single point in the curve resample node.

LineArt: Working intersection filtering.

Geometry Nodes: Improve point instance node performance

This commit uses two changes to improve the performance of the point
instance node.

**Prevent Reallocations**
At 64 bytes, the transform matrix for every instance is rather large,
so reallocating the vector as it grows can become a performance bottle-
neck. This commit reserves memory for the instances that will be added
to prevent unecessary reallocations as the instance vector grows.

In a test with 4 million instances of 3 objects in a collection, the
node was about 40% faster, from 370ms to 270ms for the node.

**Parallelization**
Currently the instances are added by appending to a vector. By changing
this slightly to fill indices instead, we can parallelize the operation
so that multiple threads can fill data at the same time. Tested on a
Ryzen 3700x, this reduced the runtime from the above 270ms to 44ms
average, bringing the total speedup to ~8x.

Note that displaying the instances in the viewport is still much slower
than the calculations in node, this change doesn't affect that.

LineArt: intersection mask ui and code.

USD Import: support animating display color.

Added missing functionality in the mesh color import logic
to support animating display color.

LineArt: show full options in first modifier.

LineArt: Data for intersection_flag
