Robostness: GLDrawableImpl's contextMadeCurrent()/contextRealized() ; GLFBODrawableImpl.contextMadeCurrent(false), OffscreenAutoDrawable.setSize(..)

GLDrawableImpl's contextMadeCurrent()/contextRealized():
  - Catch exception which may appear during callback and cont. w/ GLContextImpl's release()/destroy()
    while throwing catched exception at end.

GLFBODrawableImpl.contextMadeCurrent(false):
  - Detect null Colorbuffer ASAP and throw exception

OffscreenAutoDrawable.setSize(..):
  - Catch exceptions at 1) GLFBODrawableImpl.setSize(..) and
    2) GLContext.release() .. throw it in proper order.
