A selected live polygon now shows Illustrator's Polygon Properties in the
Transform panel and the Properties panel's Transform section: side count,
angle, corner type and radius, radius, side length and Make Sides Equal
(enabled once an uneven scale has made its sides differ). Before, only the
side count and corner radius were there.
object.setLiveShape takes polygonAngle (degrees counterclockwise),
polygonRadius and sideLength (points, centre to vertex / side) and
makeSidesEqual, which drops the uneven scale and shear and keeps the
polygon's centre, angle and mean radius. Each call is one undo step; a
radius or length that isn't a number above 0 is an error. A star stays a
plain path, as in Illustrator.
