 TODOs for Rotator:
 
-- resize rotated elements must work properly with the selector (aligned to the axis of rotation)
+- resize with negative width/height causes problems with selector (and upon release, kablooie)
+- fix resize when mouseup
 - show the proper resize cursor based on the rotation
 - add a rotator line/handle to the selector group
 - respond to mouse down on the rotator handle to start 'rotate' mode
