The ScreensaverManager is the central point where most major decision are made,
and where ScreensaverService requests are acted upon.

Activates or deactivates the screensaver. Activation involves:
- sending a request to Cinnamon to exit Overview or Expo -
this could prevent a successful screen grab and keep the
screensaver from activating.
- grabbing the keyboard and mouse.
- creating the screensaver Stage.
Deactivation involves:
- destroying the screensaver stage.
- releasing our keyboard and mouse grabs.

Called upon any key, motion or button event, does different things
depending on our current state.
If we're idle:
- do nothing
If we're locked:
- show the unlock widget (if it's already visible, this also has
the effect of resetting the unlock timeout - see Stage.py)
- show the mouse pointer, so the user can navigate the unlock screen.
If we're Active but not Locked, simply deactivate (destroying the Stage
and returning the screensaver back to idle mode.)

user-initiated activation, or slowly, when the session has gone idle.

redirected to GrabHelper, our status is updated, our active timer

Tells the stage to check its canvas size and make sure its windows are up-to-date. This is called
when our login manager tells us its "Active" property has changed. We are always connected to the
login manager, so we first check if we have a stage.
