+        There are two transitions that are currently implemented: null (the
+        default) and 'resize'.  The default transition effect is used when no
+        transition is specified and is implemented as no transition effect except
+        for panning singleTile layers.  The 'resize' effect resamples the current
+        tile and displays it stretched or compressed until the new tile is available.
