62  * <OL>
63  * <LI>All lines in SWF have rounded joins and end-caps.
64  * Different join styles and end styles can be simulated with
65  * a very narrow shape that looks identical to the desired stroke.
66  * <LI>SWF has no native support for dashed or dotted line styles.
67  * A dashed line can be simulated by breaking up the path into a series of short lines.
