Changes between Initial Version and Version 1 of Ticket #17551, comment 3

initial	v1
1		Yeah, I agree there should be an public API to provide an arbitrary image for a label. Currently the mutationscores label command monkey patches method ~~ObjectLabel._label_image(). One idea is to add an~~ ObjectLabel.label_image = None and clients can set label_image to a method and the current _label_image() will call that method if it is not None. I'd be a bit concerned how this works with session saving. The mutationscores label code does some fancy footwork in session restore to restore the monkey patches. It would be better if a public API made it less likely for you to shoot yourself in the foot on session restore.
