Detailed Description

A closed outline made of straight lines and cubic Beziers, in whatever units the caller likes.

It is how a silhouette that is not a handful of rounded rectangles is stored (the controller outlines converted from SVG are lists of these). Commands: MOVE starts a contour (1 point), LINE draws to a point (1), CUBIC draws a cubic Bezier (3: two control points, then the end), CLOSE ends the contour (0). Points are stored flat as x, y pairs.
