/**
* Calling {@link GLCanvas#removeNotify()} destroys the GLContext. We could mess with that
* internally, but this is slightly easier.
*
* <p>This method is particularly important for docking frameworks and moving the panel from one
* window to another. This is simple for normal Swing components, but GL contexts are destroyed
* when {@code removeNotify()} is called.
*
* <p>Our workaround is to use context sharing. The pbuffer is initialized and by drawing into it
* at least once, we automatically share all textures, etc. with the new pbuffer. This pbuffer
* holds the data until we can initialize our new JOGL canvas. We share the pbuffer canvas with
* the new JOGL canvas and everything works nicely from then on.
*
* <p>This has the unfortunate side-effect of leaking memory. I'm not sure how to fix this yet.
