25		* A full-service interface for HTML5 video element interaction. Allows setting
26		* and getting HTML5 video element properties. ActionListeners can be set to
27		* listen for JavaScript events associated with a video element.
28		*
29		* Video is added using a JavaScript-only two-parameter constructor for
30		* ImageIcon with "jsvideo" as the description, allowing for video construction
31		* from byte[], File, or URL.
32		*
33		* After adding the ImageIcon to a JLabel, calling
34		* jlabel.getClientProperty("jsvideo") returns an HTML5 object of type
35		* HTML5Video (the <video> tag), which has the full suite of HTML5 video
36		* element properties, methods, and events.
37		*
38		* Access to event listeners is via the method addActionListener, below, which
39		* return an ActionEvent that has as its source both the video element source as
40		* well as the original JavaScript event as an Object[] { jsvideo, event }. The
41		* id of this ActionEvent is 12345, and its command is the name of the event,
42		* for example, "canplay" or "canplaythrough".
43		*
44		* See https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement for
45		* details.
