* Masks: set the corner roundness of a Rounded Rectangle mask (#3067)
layer.addMask takes a roundness (corner radius in px) for shape rounded, and the new
mask.setRoundness changes it afterwards on a rectangular mask.

* Mask roundness: refuse ellipses, keep feather points and key correspondence
mask.setRoundness accepted any closed path whose vertices lie on its bounding
box, so an ellipse was replaced by a rectangle. It now accepts only a plain
rectangle (four corner vertices, straight sides) or a rounded one (eight
vertices, straight sides alternating with circular corners).
The rebuilt path keeps the old start vertex and direction, and its feather
points, so an animated path's other keys and the feather points still line
up. A change between square and rounded corners changes the vertex count; it
is refused when the path is keyed or has feather points instead of leaving
keys with different counts or dropping the points.

A slip on a layer with no source handles succeeded with `delta: 0` and nothing else, which
read like a no-op bug. The result now carries `requested` (seconds) and, per layer, `clamped`
when the source could not move that far.

Text strokes were always drawn with round joins. The document gets a
Line Join (`lineJoin: miter|round|bevel` in layer.setText / newText),
Miter for new text as in After Effects, Round for documents saved before
it so their look is kept. The 2D and Advanced 3D (extruded) text strokes
use it, expressions' style copies carry it, and the Character panel has
Miter / Round / Bevel buttons under the stroke width.

Opening the editor keeps the keyframe and mask-vertex selection as well as the property one,
and Duplicate cleared only the properties. With the copy selected, Clear then deleted a key or
vertex of the original instead of the copy. During an edit the copies now take the selection the
way a click on them does: layer.select's rule, moved into one helper both use. With no edit
open, Duplicate's selection is unchanged.
