Outstanding Issues / Questions
===============================================================================
* Do we need rotations (if so, this will require significant code changes)
* Should undo/redo consider only your actions, or all actions?
* What about undo/redo with an item that is currently in use by another person?
* Currently, the image db doesn't detect duplicates.
* Large image support is missing
* Add server "locking" support at the whiteboard level
* Alpha fill for free-form polygon will overlap stroke
* Some events still binded within the NRCWhiteboard "class". API should
allow user to set them.
