device_id_max is set to the device_id in ensure_device_monitor(), but we
will loop only to (device_id_max - 1) when propagating the sync XEvent
down, missing the device correspondng to device_id_max.

The protocol specification says that opaque / input regions should be
considered pending state and should only be actually swapped out when
the surface is committed, so it can be set atomically.
We had an assertion in meta_wayland_surface_free() that after
a repick() we would not choose the freed surface, but that didn't
consider surfaces destroyed while holding the implicit pointer
grab (ie, because the user clicked on the X button). In that case,
we need to bypass the grab infrastructure and explicitly unfocus
the dead surface.
https://bugzilla.gnome.org/show_bug.cgi?id=706982
After a MetaWaylandSurface is associated with a MetaWindow, it
should be freed only when the MetaWindow is unmanaged. For wayland
clients, the window is unmanaged when the resource is destroyed,
but for X11 clients we want to wait for the unmap event.
https://bugzilla.gnome.org/show_bug.cgi?id=705917
Calling XIGrabDevice has no effect under wayland, because the
xserver is getting events from us. Instead, we need to use our
own interfaces for grabs.
At the same time, we can simplify the public API, as plugins
should always listen for events using clutter.
https://bugzilla.gnome.org/show_bug.cgi?id=705917
We need to track the full xkb_state to have the necessary information
to send to the clients, otherwise they may get confused and lock
or invert the modifiers. In the evdev backend, we just retrieve the
same state object that clutter is using, while in the other backends
we fake the state using what clutter is providing (which is a subset
of what X11 provides, which would be necessary to have full state)
https://bugzilla.gnome.org/show_bug.cgi?id=705862
Once mutter is started from weston-launch on its own VT, there is
no way to change VT again (for example to actually start an application),
because the keyboard is put in raw mode.
So introduce some keybindings mimicking the standard X ones (Ctrl+Alt+Fn)
that switch the VT manually when activated.
https://bugzilla.gnome.org/show_bug.cgi?id=705861
Now that we have a setuid launcher binary, we can make use of
using a private protocol through the socket we're passed at startup.
We also use the new hook in clutter-evdev to ask mutter-launch for
the FDs of the input devices we need, and we emulate the old X
DRM lock with a nested GMainContext without sources.
In the future, mutter-launch will be replaced with the new logind
API currently in development.
https://bugzilla.gnome.org/show_bug.cgi?id=705861
Set the TTY mode appropriately at startup, and clean it up
when the compositor exits. Also, take control of VT switching,
including the calls to drmSetMaster and drmDropMaster as appropriate.
In the future, we the kernel implements the mute evdev ioctl,
we'll also make sure that input devices are appropriately released.
https://bugzilla.gnome.org/show_bug.cgi?id=705861
Being a setuid binary, our LD_LIBRARY_PATH is cleared by glibc at
startup, but we need the spawned binary to see it, otherwise
jhbuild doesn't work, so hardcode it using the configured libdir.
https://bugzilla.gnome.org/show_bug.cgi?id=705861
Remove the ability to launch as a different user, which we don't
need because we're spawned by gdm or by the user manually on the
command line.
At the same time, require an active local session, and remove
the ability to run from anywhere by being in the right user group
(which automatically gives you root-like privileges)
https://bugzilla.gnome.org/show_bug.cgi?id=705861
To run mutter as a display server, one needs to acquire and
release the DRM master, which is only possible for root, so
we take advantage of weston-launch, a small setuid helper binary
written for the weston project. We import our own slightly
modified copy of it, because weston-launch only launches weston,
for security reasons.
https://bugzilla.gnome.org/show_bug.cgi?id=705861
We must send frame_drawn and frame_timing messages to even when
we don't actually queue a redraw on screen to comply with the
WM sync spec.
So throttle such apps to down to a ~100ms interval.
https://bugzilla.gnome.org/show_bug.cgi?id=703332
When we get a damage event we update the window by calling
meta_shaped_texture_update_area which queues a redraw on the actor.
We can avoid that for obscured regions by comparing the damage area to
our visible area.
This patch causes _NET_WM_FRAME_DRAWN messages to be not sent in some cases
where they should be sent; they will be added back in a later commit.
https://bugzilla.gnome.org/show_bug.cgi?id=703332
When drawing entirely opaque regions, we traditionally kept blending on
simply because it made the code more convenient and obvious to handle.
However, this can cause lots of performance issues on GPUs that aren't
too powerful, as they have to readback the buffer underneath.
Keep track of the opaque region set by windows (through _NET_WM_OPAQUE_REGION,
Wayland opaque_region hints, standard RGB32 frame masks or similar), and draw
those rectangles separately through a different path with blending turned off.
https://bugzilla.gnome.org/show_bug.cgi?id=707019
Split out pipeline creation to a separate function so that we don't
have so much dense code in the paint function itself, and remove some
indentation levels.
Also, don't use our own template for the unmasked pipeline, since it
has nothing different from the default pipeline template.
We also don't store the pipelines anymore since their creation isn't
really helping us; we set the mask texture and paint texture on every
paint anyway.

The user active watch is a one-fire watch, but it is valid in the API
for the callback to explicitly remove the watch itself. In that case,
the watch will be invalid after the user removes it, and the memory
potentially freed. So make sure to not dereference the watch after
the callback is called.
https://bugzilla.gnome.org/show_bug.cgi?id=706825
Dialogs that don't have a parent should not be skip-taskbar,
otherwise they get lost and there is no way to recover them
(because they're not autoraised when activating the parent),
but toolkits and applications set the hint anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=673399
Modify all visible instances of mutter with mutter-wayland
(libraries, folders, pkgconfig, etc.), so that the wayland
branch can be installed alongside the usual X11 mutter.
https://bugzilla.gnome.org/show_bug.cgi?id=705497
In the wayland branch of mutter, we want to build a wayland version
of the mutter libraries, and that's much easier if we just build
wayland support unconditionally.
The define is kept to avoid a huge diff, but should be removed
in a later patch.
Also, wayland support can still be disable at runtime, by
launching mutter without the --nested switch.
