GLJPanel: Fix dispose of backend (J2DOGL thread, no double dispose)..,

GLJPanel:
- fix dispose of backend
  - proper J2DOGL thread
  - no double dispose
- remove VERBOSE
- no dispose regenerate flag
- add @Overrride
- more safe createContext(..) impl
- setSynchronized(true); for all backends
- ensure AbstractGraphicsDevice close() is being called

GLDrawableHelper:
- Clarify w/ isDisposeAction = null==initAction

GLPbufferImpl:
- ensure AbstractGraphicsDevice close() is being called

Java2D:
- remove VERBOSE
-
