---------------------------+------------------------------------------------
 The MgLegend component does not currently handle large maps very well
 (with 100s of layers). This is because of primarily 2 things:

  1. We are excessively doing work on the GUI thread, which is a bad thing
 for large maps.
  2. We are also not caching layer icons
