[Issue 583] A disposed Graphics2D remains in Canvas3D after removal and addtion

The previous patch didn't fix everything, since the dispose method was called
from elsewhere (Finalizer). I added an isDisposed() method to J3DGraphics2DImpl
and I'm checking that in the getGraphics2D() method of Canvas3D. I'll post a
patch soon.
