gdk_device_manager_get_client_pointer which in calls
XIGetClientPointer seems to be very slow in a XI2 world.
So use
gdk_x11_device_manager_lookup (gmanager, META_VIRTUAL_CORE_POINTER_ID)
instead.

This new hint allows compositors to know what portions of a window
will be obscured, as a region above them is opaque. For an RGB window,
possible to glean this information from the bounding shape region of
a client window, but not for an ARGB32 window. This new hint allows
clients that use ARGB32 windows to say which part of the window is
opaque, allowing this sort of optimization.

With the shape region always set, it turns out the bounding region
is only used in one place, that's easily replaced with a variable
we already have available to us.

With recent changes in the way the window mask texture is constructed,
the shape_region is always set, which means that we can remove
conditionals checking if the shape region is set.

Currently we only unredirect monitor sized override redirect windows.
This was supposed to catch fullscreen opengl games and improve
their performance.
Newer games like fullscreen webgl games and SDL2 using games (like L4D) as well as wine based games do not use override redirect windows so we need a better
heuristic to catch them.
GLX windows always damage the whole window when calling glxSwapBuffers and
never damage sub regions. So we can use that to detect them.
The new heuristic unredirects windows fullscreen windows that have damaged the
whole window more then 100 times in a row.

We should call meta_window_actor_detach not
meta_window_actor_queue_create_pixmap to create a new pixmap when we redirect a
previously unredirected window again.

We want to put barrier wrappers in mutter, which requre XFixes 5.0.
XFixes 5.0 was released in March, 2011, which should be old enough
to mandate support for.

Using a public method for setting the (cached) icon geometry rather
than accessing the struct members directly allows setting the icon
geometry from extensions.

We have some code in gnome-shell that does the equivalent of:
window.get_workspace() == workspace || window.is_on_all_workspaces();
which is a bit unwieldy. We already have a method in mutter,
so use that and document it.

With some recent changes to how mask textures are constructed from
shapes, a helper method we made was only called in one place, allowing
us to drop a reference/destroy, and remove a double clear.

Due to a conditional error, meta_region_builder_add_rectangle was called
on every single blank pixel, rather than at the end of spans. With the new
rename, it's fairly clear to see the error. Fix the check to ensure that
we no longer make extraneous calls to meta_region_builder_add_rectangle.
