/**
 *
 * Path contain geometry. Path may be empty, or contain one or more verbs that
 * outline a figure. Path always starts with a move verb to a Cartesian coordinate,
 * and may be followed by additional verbs that add lines or curves.
 *
 *
 * Adding a close verb makes the geometry into a continuous loop, a closed contour.
 * Path may contain any number of contours, each beginning with a move verb.
 *
 *
 * Path contours may contain only a move verb, or may also contain lines,
 * quadratic beziers, conics, and cubic beziers. Path contours may be open or
 * closed.
 *
 *
 * When used to draw a filled area, Path describes whether the fill is inside or
 * outside the geometry. Path also describes the winding rule used to fill
 * overlapping contours.
 *
 *
 * Internally, Path lazily computes metrics likes bounds and convexity. Call
 * [.updateBoundsCache] to make Path thread safe.
