Discrete Perspective Viewer Events #2941
Description
Feature Request
Description of Problem:
I would like to take selective action when various events occur in the perspective-viewer, such as when it loads, is restored, or the user changes the viewer config. As of writing, I can monitor these via perspective-config-update, but I don't know which one triggered the event. I can potentially use event.target.getTable() to determine whether it was from a load event, but to my current knowledge, I cannot discern between a call to restore() and user interaction.
Potential Solutions:
Dispatch discrete events when various things happen in the viewer. perspective-load, perspective-restore, perspective-user-config, etc.
