Glass thread checks

[steve.x.northover at oracle.com]

Heavens .. typos!

To give a little more context.  JavaFX is apartment threaded with well 
documented rules for threading.  These rules were not enforced in code.  
Glass, the low level window component for FX is now enforcing apartment 
threading for this component.  Since Glass has no public API, the only 
way that an application can be affected is if it is coded such that it 
accesses Glass through FX from a non-UI thread.  FX itself contained 
code some code that did this this code has been fixed.

Thread checking is goodness and leads to consistent applications with 
repeatable behavior.  Thread checking in Glass is a good first step 
forward towards finding and addressing thread bugs.
