Should the observers be in XDE-ISIRController?

[sovannara-hak]

XDE-ISIRController contains a couple of observers,
but some of them are not related to the controller, typically, the screenshot grabber.

Should we move all/part of the observers to XDE-WorldManager ?

How can we do it without breaking old scripts ?

You're right, some parts should belong to something else than the controller.
A possible way would be to define an observer class into a mandatory package (in XDE-WorldManager, or by reusing the XDE-Observers previously defined), to copy these observers into this package (by respecting the pattern based on an update method with no arguments), and to create a proxy in XDE-ISIRController to avoid broken script as follows:
"""
import mandatoryPakage
theObserver = mandatoryPakage.theObserver
"""
What do you think?

That's an excellent idea, thanks!
