Suspicious Code: 

- look for //TODO's in the code 
- the code that positions a stage (popup or regular) is suspicious and contains instanceof 
- table has some arrow key behavior that is not accounted for and appropriately flipped 
- text field skin getAlignment() may not account for all alignment combinations that can occur 

Possible bug: TextArea creates Text nodes based on the current effective orientation.  If that changes, the Text nodes are not updated (need to write a test case to prove this).
