If a Pbuffer is destroyed while a context created on that Pbuffer is current, an
exception will result the next time any context is made current. One could argue
that this is an app bug, but I am fairly certain that native OpenGL drivers
handle this case correctly.

To reproduce, run the attached test program. When you press the "DestroyPbuffer"
button, a new context is created on the Pbuffer, the new context is made
current, then the Pbuffer is destroyed. The following exception is thrown the
next time the on-screen context is made current:

Exception in thread "AWT-EventQueue-0" javax.media.opengl.GLException: Pbuffer
destroyed out from under application-created context

Note that if you check the "Release pcontext" check box prior to pressing the
"Destroy Pbuffer" button, then the app will release the context prior to
destroying the pbuffer and there will be no exception.
