We don't get notifications from X11 when the mode is reset, so
our cached value can get stale. To work around that, always forward
requests to the backend (and let it deal with ignoring the change
if wanted)

Use the new Clutter hook to make sure the pointer never enters
the dead area caused by the different monitor sizes.
You don't realize how much X is doing for you until you lose it...

The meta_create_texture_pipeline function used to create a dummy 1x1
texture so that it could make sure that the all of the state that
affects the shader generation would be set on the template pipeline so
that Cogl could share the pipeline's shader with any other pipelines
that are just rendering a texture. This is no longer necessary because
the only thing that affects the shader generation is the texture type,
not the actual texture data and Cogl now has a function to explicitly
set the texture type which we can use instead. Additionally even if
the template mechanism is not used at all Cogl will still end up
reusing the same shader because it now has a shader cache which is
indexed by the pipeline state so pipeline's don't strictly need to
share ancestry in order to take advantage of it. However we still
might as well use the function because if there is a common ancestry
it is faster to look up the shader because Cogl doesn't need to hash
the pipeline state.

(cherry picked from commit c5bf60eab4)
Add a new interface, gtk_shell, than can be used by gtk to
retrieve a surface extension called gtk_surface, which will be
used to communicate with mutter all the GTK extensions to EWMH
https://bugzilla.gnome.org/show_bug.cgi?id=707128
Add support for GTK application menus
To do so, we need to be able to set surface state before creating
the MetaWindow, so we introduce MetaWaylandSurfaceInitialState as
a staging area.
The gtk-shell-surface implementation would either write to the
initial state, or directly to the window.
At the same, implement set_title and set_class too, because it's
easy enough.
https://bugzilla.gnome.org/show_bug.cgi?id=707128
According to the wayland documentation, damage outside the
window size is ignored.
This happened with xwayland+wlshm (causing a GL error when calling
TexSubImage2D), probably due to not resizing the buffer
until we receive the corresponding X event.
Might also be an off-by-one in xwayland, as the window size did
not actually change.
Note: we might want to take the configure_notify path instead,
and keep the GL/clutter size consistent with wayland rather than
X, because in the end that's what matters for events and composition.
https://bugzilla.gnome.org/show_bug.cgi?id=706289
If, checking the event timestamps, we see that a new configuration
was explicitly requested by an another XRandR client, don't proceed to
apply the intended configuration again, even if looking at the
EDIDs it appears that the outputs changed.
This works around some buggy Xorg drivers (qxl, vbox) that generate
a new serial number everytime the user resizes the host window.
https://bugzilla.gnome.org/show_bug.cgi?id=706735
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.
https://bugzilla.gnome.org/show_bug.cgi?id=707250
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.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=705497
If we're attempting to reconfigure the CRTCs to the same parameter,
skip the X call, as in some drivers a modeset can take time and
cause flicker.
https://bugzilla.gnome.org/show_bug.cgi?id=706672
To allow other clients (gnome-session, gnome-settings-daemon)
to monitor user activity, introduce a DBus interface for the
idle monitor inside mutter.
https://bugzilla.gnome.org/show_bug.cgi?id=706005
When running as a wayland compositor, we can't use the xserver's
IDLETIME, because that's updated only in response to X events.
But we have all the events ourselves, so we can just run the timer
in process.
https://bugzilla.gnome.org/show_bug.cgi?id=706005
We can't use the X11 stage window, if clutter is not using the X11
backend (and even if it was, it would be bogus when the xwayland
server is not the one clutter is talking to). Instead, we introduce
the concept of "focus type", which we use to differentiate the
various meanings of None in the focus_xwindow field.
https://bugzilla.gnome.org/show_bug.cgi?id=706364
Remove grab window and cursor from the API, and just grab always
on the stage window with no cursor.
This is mainly to remove the X11 usage in the public API, in preparation
for implementing this in wayland.
https://bugzilla.gnome.org/show_bug.cgi?id=705917
Using out-of-band notifications from the wayland protocol or from
X is racy, in that the client could ask for the new resources before
we have them.
Instead, with a signal, we are sure that when the client asks for
it, it will get the right values.
https://bugzilla.gnome.org/show_bug.cgi?id=706382
Under X, we need to use XFixes to watch the cursor changing, while
on wayland, we're in charge of setting and painting the cursor.
MetaCursorTracker provides the abstraction layer for gnome-shell,
which can thus drop ShellXFixesCursor. In the future, it may grow
the ability to watch for pointer position too, especially if
CursorEvents are added to the next version of XInput2, and thus
it would also replace the PointerWatcher we use for gnome-shell's
magnifier.
https://bugzilla.gnome.org/show_bug.cgi?id=705911
The value passed to XRRCrtcSetGamma must be allocated with
XRRAllocGamma (because it relies on the locations of green and blue),
otherwise garbage is sent on the wire.
https://bugzilla.gnome.org/show_bug.cgi?id=706231
We were relying on the XRandR events from the X server to update
the configuration, but we were calling meta_monitor_config_update_current()
immediately after, so the MonitorConfig would be updated with the
old configuration (and we would save that to disk!)
https://bugzilla.gnome.org/show_bug.cgi?id=705670
First disable CRTCs that should be off in the new configuration,
then resize the framebuffer, then enable the new CRTCs.
If we don't do that, and we're making the screen smaller, X complains
with a BadMatch.
https://bugzilla.gnome.org/show_bug.cgi?id=705670
Add "edid-file", if we have one (in the KMS case, where we can point
people to the right sysfs file), or "edid" with inline data.
These are needed by colord to build the default ICC profile for
uncalibrated displays.
https://bugzilla.gnome.org/show_bug.cgi?id=705670
Instead of keeping a forest of if backend else ..., use a subclass
and virtual functions to discriminate between XRandR and the
dummy backend (which lives in the parent class togheter with the
common code)
https://bugzilla.gnome.org/show_bug.cgi?id=705670
We want to show a dialog when a display change happens from the
control center. To do so, add a new vfunc to MetaPlugin and
call it when a configuration change is requested via DBus.
https://bugzilla.gnome.org/show_bug.cgi?id=705670
Add GetCrtcGamma() and SetCrtcGamma(), that wrap the similarly
named XRandR API. These are used by GnomeRR inside the color
plugin of the control center (and may go away if the color
plugin decides to do something different under wayland)
https://bugzilla.gnome.org/show_bug.cgi?id=705670
GnomeRR needs that too.
The backlight is exported as a normalized 0-100 value, or -1 if not
supported. Clamping to HW limits is handled by the backend.
Changing backlight uses a different method call, to avoid recomputing
the full display configuration every time the user presses the
backlight keys.
https://bugzilla.gnome.org/show_bug.cgi?id=705670
The default configuration is extended, which is only possible
if there are as many CRTCs as outputs, so make sure that's true.
Also, add more and bigger modes, so that different sizes will
be chosen for the three outputs.
A nice side effect of this is that with a real 1920x1080 + 1600x900
layout, if you disable the VGA you get a stage that matches the
screen size, which triggers the legacy fullscreen path in the
outside mutter.
https://bugzilla.gnome.org/show_bug.cgi?id=705670
Use a private output property to store if the output is in
presentation mode or not, so that this information is not lost
after the configuration read back from the server.
