Dispose of an image within a Draw2D Label [message #214415]

What's the best practice for disposing system resources when using a Draw2D
label? My model element knows what color and what image, but my controller
(EditPart) creates them as I don't want my model to manage system resources
and I wanted testable in headless mode. The EditPart interface doesn't
support a dispose method, so I'm looking for a "best practice".

The best practice is to use a resource manager scoped at your editor.
Editparts do have a lifecycle. deactivate is always called. removeNotify()
is called when deleted.

Use a global resource manager for your entire plug-in. Use a nested local
manager for each editor instance. get the images using getImage, and clear
them using destroyImage().
