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.

The curtain animation looks jerky at its current speed, and more so if
we blank the screen immediately at the end. Make it a little slower and
it becomes more confortable.

When there are multiple sessions, we may get a polkit dialog in
response to clicking 'Reboot' in the end session dialog. If the
polkit dialog gets canceled or otherwise ends unsuccessfully,
we are left with the lightbox that the end session dialog puts
up when 'Reboot' is clicked. To remove the lightbox and make the
session fully functional again, gnome-session will call Close.

We have to mark the cairo_surface dirty after modifying the data behind
cairo's back.
Also use CAIRO_FORMAT_ARGB32 rather then CAIRO_FORMAT_RGB24 for the
surface to be consistent with the rest of the code.

Instead of using Clutter to add an event filter for X events it now
uses the GDK API. The Clutter API won't work if Clutter is not using
an X11-based backend such as if Mutter is directly running with the
KMS backend. This is a step towards making Mutter be its own display
server and a step towards being a Wayland compositor. In this case GDK
will still be using the X backend because it will connect to the
headless X server.

A pressure barrier is a barrier that activates after the user pushes
against the bottom of the screen in a short time. Implement this using
the new XInput 2.3 features that provide extended information about
pointer barriers, and use it so that pushing against the bottom of
the screen edge brings up the message tray.
https://bugzilla.gnome.org/show_bug.cgi?id=677215
As pressure barriers need a signalling mechanism to provide
information about when and where they are hit, an object which
provides a signal is a more appropriate abstraction for a pointer
barrier than a functional ID-based approach. Mutter has gained
pointer barrier wrappers, so use its objects instead of ours.

Before version 1.2 of GLSL it would not implicitly convert from int to
float which meant that if you compare a float variable with an integer
constant it will generate a compile error. In particular this means
that on GLES2 (which uses GLSL 1.0) the scroll view shader will not
compile on pedantic compilers, which includes Mesa. This patch just
changes it to use floating point constants.

Since the panel affects struts, if we change its height on mode
transitions, windows will move around which is particularly noticable
with maximized windows when coming out of the screen shield.
https://bugzilla.gnome.org/show_bug.cgi?id=692966
This, together with the panel's transparent background in the screen
shield, has the unfortunate side-effect of showing the desktop
background in a brief flash while coming out of the screen shield.
