Add a private hook for the test framework to get XSyncAlarmEvent events -
this will be used to implement XSyncCounter based synchronization
so that the test framework can deterministically wait until Mutter
has seen actions performed by an X11 client.

Add private functions for the test framework to use to find out the
wayland and x11 display names, so they can set up the environment for
children.

mutter-test was a script that was used to run various test on the
Metacity source tree (build with different options, etc.) This likely
hasn't been run once since the Metacity/Mutter branch point; remove
it to avoid confusion with the new test framework in src/tests.

We'll need this in the wayland frontend to send a modifiers event to
clients.
Note that on X11 this isn't needed because key events include the
group index encoded in modifier state. If we ever want to make the
wayland frontend work with the X11 backend we'll handle it then.

According to the documentation, the method returns "whether the X window
that the actor was displaying has been destroyed" - that is very much
true when we delay the actual actor destruction for a destroy animation,
so update the method accordingly.
https://bugzilla.gnome.org/show_bug.cgi?id=735927
When a window is destroyed, the corresponding actor may still be
kept around for the destroy effect. But as the actor is removed
from the compositor's stack list immediately, the compositor will
always stack it above "valid" window actors - this is not what we
want, so only update the compositor's list when the actor is
actually destroyed.
https://bugzilla.gnome.org/show_bug.cgi?id=735927
Setting the scaling factor immediately after calling clutter_init()
avoids creating the stage at one size, then later resizing it to
a different size.
https://bugzilla.gnome.org/show_bug.cgi?id=736279
In the case of a nested Wayland compositor inside an X session,
Clutter is managing the toplevel window size, so don't call
XResizeWindow on it - this will confuse Clutter and get the size
and the hints out of sync on the toplevel window.
https://bugzilla.gnome.org/show_bug.cgi?id=736279
It's possible for a released pointer to have repick / set_focus on it as
part of sync_input_focus. When the pointer is actually re-init'd, it
will memset 0, which can cause corruption as our destroy listener has
already been added.
Released devices should be idempotent, so just make sure method calls on
them don't have any effect.
We can enter weird states where get_default_window is called during
window unmanagement, before the window has been fully removed from
the stack. Make sure these windows are *never* returned from
get_default_window, as focusing them can cause an assertion fail,
or worse.
If we add device 2, then add device 254, then remove device 254, then
the max device ID will be 253. Scan through all the devices again on
removal to calculate a new max device ID.
Rather than have the DBus code control this, move this into
MetaBackend. This also lets us destroy idle monitors when appropriate,
rather than leaking them forever.
Not having a paint volume causes every single paint to turn into
full-stage redraw, since otherwise culling won't properly work.
Since we don't paint outside of our allocation, just use the simple
default implementation, but also return TRUE inside it.
Make the vignette options properties so they can be animated;
modify the function-call API for meta_background_actor_set_vignette()
to correspond more closely to the 3 properties.
https://bugzilla.gnome.org/show_bug.cgi?id=735637
Without GLSL, we didn't apply the vignetting, which not only made the
background uniform in color, it made it much lighter. Adjust for this
and make the average brightness with the vignette effect the same
with or without GLSL.
https://bugzilla.gnome.org/show_bug.cgi?id=735637
The old requirement that multiple MetaBackgroundActor objects be
layered on top of each to produce blended backgrounds resulted in
extremely inefficient drawing since the entire framebuffer had
to be read and written multiple times.
* Replace the MetaBackground ClutterContent with a plain GObject
that serves to hold the background parameters and prerender
textures to be used to draw the background. It handles
colors, gradients, and blended images, but does not handle
vignetting
* Add vignetting to MetaBackgroundActor directly.
* Add MetaBackgroundImage and MetaBackgroundImageCache to allow
multiple MetaBackground objects to share the same images
By removing the usage of ClutterContent, the following optimizations
were easy to add:
Blending is turned off when the actor is fully opaque
Nearest-neighbour filtering is used when drawing 1:1
The GLSL vignette code is slightly improved to use a vertex shader
snippet for computing the texture coordinate => position in actor
mapping.
https://bugzilla.gnome.org/show_bug.cgi?id=735637
The old check for using NEAREST by checking clutter_actor_is_in_clone_paint()
and meta_actor_is_untransformed (actor) doesn't work properly since
clutter_actor_is_in_clone_paint() does not look at ancestors of the
actor; it only applies to a direct clone of the actor. Using
meta_actor_painting_untransformed() allows us to check exactly what we
care about rather than using tricky approximations.
https://bugzilla.gnome.org/show_bug.cgi?id=735632
The painting_untransformed() function in MetaWindowGroup is useful
elsewhere, in particular if we want to check whether we can avoid
bilinear filtering when painting a texture 1:1.
https://bugzilla.gnome.org/show_bug.cgi?id=735632
Clutter events include the layout index codified into modifier_state,
unlike XI2 device events, which means that we need to mask it out so
that we can match successfully.
A lot of applications assume that the window is fully positioned when it
gets the MapNotify, especially simple applications. Make sure that the
window is only mapped through the calc_showing logic.
