Shapes: add the Wiggle Transform path operation, which wiggles paths and each Repeater copy

A shape layer's Contents > Add menu had every After Effects path operation
except Wiggle Transform. It is now a shape item (layer.addShapeItem kind
wiggler, "ADBE Vector Filter - Wiggler" for scripts) with Wiggles/Second,
Correlation, Temporal Phase, Spatial Phase, Random Seed and a Transform
group whose Anchor Point, Position, Scale and Rotation set how far each
transformation wiggles.

The values come from the Wiggly selector's noise, with each Repeater copy
as one unit: the copies of a Repeater above the operation, in its group or
a nested one, wiggle independently as far as Correlation allows, and the
copies of a Repeater below it wiggle the same way. A paint above it whose
paths all move by one matrix moves its gradient and stroke scale with them.
The layer cache keys a layer with a Wiggle Transform by time.
