  * @fileoverview Interactive visualizaiton of TimelineModel objects
  * based loosely on gantt charts. Each thread in the TimelineModel is given a
  * set of TimelineTracks, one per subrow in the thread. The Timeline class
  * acts as a controller, creating the individual tracks, while TimelineTracks
  * do actual drawing.
  *
  * Visually, the Timeline produces (prettier) visualizations like the following:
  *    Thread1:  AAAAAAAAAA         AAAAA
  *                  BBBB              BB
  *    Thread2:     CCCCCC                 CCCCC

    * The TimelineViewport manages the transform used for navigating
    * within the timeline. It is a simple transform:
    *   x' = (x+pan) * scale
    *
    * The timeline code tries to avoid directly accessing this transform,
    * instead using this class to do conversion between world and view space,
    * as well as the math for centering the viewport in various interesting
    * ways.
