/*==================================================
 * 
 * To enable a single event listener to monitor everything
 * on a Timeline, we need a way to map from an event's icon,
 * label or tape element to the associated timeline, band and
 * specific event.
 *
 * Thus a set format is used for the id's of the 
 * events' elements on the Timeline--
 * 
 * element id format for labels, icons, tapes:
 *   labels: label-tl-<timelineID>-<band_index>-<evt.id>
 *    icons: icon-tl-<timelineID>-<band_index>-<evt.id>
 *    tapes: tape1-tl-<timelineID>-<band_index>-<evt.id>
 *           tape2-tl-<timelineID>-<band_index>-<evt.id>
 *           // some events have more than one tape
 *    highlight: highlight1-tl-<timelineID>-<band_index>-<evt.id>
 *               highlight2-tl-<timelineID>-<band_index>-<evt.id>
 *           // some events have more than one highlight div (future) 
 * You can then retrieve the band/timeline objects and event object
 * by using Timeline.EventUtils.decodeEventElID
 *

 *    eventPaintListener functions receive calls about painting.
 *    function(band, op, evt, els)
 *       context: 'this' will be an OriginalEventPainter object.
 *                It has properties and methods for obtaining
 *                the relevant band, timeline, etc    
 *       band = the band being painted
 *       op = 'paintStarting' // the painter is about to remove
 *            all previously painted events, if any. It will
 *            then start painting all of the visible events that
 *            pass the filter. 
 *            evt = null, els = null
 *       op = 'paintEnded' // the painter has finished painting
 *            all of the visible events that passed the filter
 *            evt = null, els = null
 *       op = 'paintedEvent' // the painter just finished painting an event
 *            evt = event just painted
 *            els = array of painted elements' divs. Depending on the event,
 *                  the array could be just a tape or icon (if no label).
 *                  Or could include label, multiple tape divs (imprecise event),
 *                  highlight divs. The array is not ordered. The meaning of
 *                  each el is available by decoding the el's id 
 *      Note that there may be no paintedEvent calls if no events were visible
 *      or passed the filter.
