Description

IJ2 makes shadow IJ1 images when legacy plugins are run. These images don't go away until the IJ2 display is closed. Its possible that in tight memory situations a user might want to purge the IJ1 images. Enable some hotkey or menu command that can do this.

We are no longer supporting use of ImageJ 1.x commands from modern ImageJ2 UIs, so this issue is now moot.

As for the other direction: when running the legacy ImageJ 1.x UI, ImageJ2 shadow ImageDisplays are only created when the "Enable ImageJ2 data structures" option is checked, and it is now unchecked by default. So most users will be unaffected by any related problems. If a user turns on that option, they can still purge the linkages manually by writing a script that access the LegacyImageMap, etc. This is such a rare use case that I see no need for a dedicated built-in command. We can add one later if/when the need arises.
