In converting from PShapes to Geometries, it was assumed until now that in shapes having multiple contours, every contour beyond the first must represent a hole.

Here's one counter-example to this assumption, where each band of the letter is not a child shape, but a contour:

To convert such shapes properly the code must check the winding of each contour: if it winds in the opposing (usually counter-clockwise) direction to the first contour, it represents a hole; if it winds in the same direction as the first contour, it represents another shape feature and should be preserved.
