Drew Dibble 9bd8b69613 3D effects: resolve overlapping contours before building a solid ...

Extrude & Bevel, Inflate and Rotate broke on shapes whose contours cross.
Type often draws a glyph that way: Roboto Slab's "k" has its arm and leg
as one contour that crosses both the stem and the leg's foot serif.

rings() decided each contour's role (outline, hole, or no edge at all
under nonzero) from the contour's first point only. A contour that starts
inside another was dropped or flipped into a hole, cutting part of the
glyph away. A contour that starts outside was kept whole, so its walls and
bevels ran through the overlap and the overlapping parts drew as separate
boxes.

The profile now goes through vectorcraft_pathops::try_normalize first, so
rings() only ever sees simple contours that do not cross. A path the
boolean refuses is used as it was.
