ef09596648 ScreenShield: don't allow events through the lock dialog
Make the lock dialog group reactive, to intercept any events
before they go to the actors below.
In the future, we may restructure our chrome to have a clear
layer system, but for now it fixes a security issue in the lock
screen (you can see the contents of the windows by dragging
if the screen was locked with the overview active)

24f142df1d ScreenShield: animate new notifications
Showing the new message at full size marks an abrubt change and looks
bad. Instead, gradually animate from 0px to full natural height.
Includes hacks to workaround flickering scrollbars while the animation
is in progress.

7652f4272c ScreenShield: remove curtain animation when hiding without animation
If we don't remove the animation, we might leave a pending call

ded99b9a09 screenShield: defer deactivation until all messages are shown
Right now when a user types their password to unlock their session
we end up getting an unlock signal from GDM right away.  We then
proceed to deactivate the screensaver before the user has a chance
to read his messages.

This commit makes sure we clear out the message queue before processing
the deactivation request.

55a04bbf2b unlockDialog: don't unlock explicitly on verification-complete
logind sends out an "unlock" signal separately when
verification completes and we already listen for that,
so we don't need to unlock on verification-complete, too.

d509ab7779 ScreenShield: when the user goes idle, check for active before pushing a modal
We can't assume "isActive implies isModal", so there is a risk
of pushing a modal that nothing else will ever pop, because we
take the early return and don't activate the user active watch.

ba198034cb screenShield: Remove blur and desaturation from lock screen

that make the screen shield hard to use on slower computers, and this

4b3bf05aaf screenShield: Only release logind inhibitor on suspend
To make sure that the screen shield is shown before suspending, we
take a logind inhibitor and release it when the screen shield is
shown. As the screen shield is not only shown on suspend, we can end
up releasing the inhibitor independently from suspending (lock, idle),
in which case the screen might not be locked when we do suspend.
To fix, only release the inhibitor after showing the screen shield
when we are about to suspend.

d5e647a191 ScreenShield: fix positioning of background with multimonitor
Previously, we would create one StBin per monitor, but each was positioned
at 0,0 and sized as the screen, so they would overlap and draw the box shadows
on top of the other backgrounds.
Instead, we need to size appropriately the bin, and then we need to position
the actual MetaBacgroundActor at 0,0, so add a flag to BackgroundManager
for this.
Also, get rid of MetaBackgroundGroup, they do nothing because the screenshield
is not a descendant of the MetaWindowGroup and because the widget in between
blocks the propagation of the visible region. At the same time, use a
widget, not a bin, because StBin requires you to set .child, not call add_child().

4dc9540325 ScreenShield: try harder to become modal, and catch failures
The screenshield was not checking the return value of pushModal(), meaning
that it believed it was fully locked when it was not. Later, calling
popModal() would fail, causing an exception and blocking the unlock.
Now when we fail we include an explanatory message, pointing the user
to the actual cause of the issue.
