When managing a non-OR window we're required by the ICCCM to behave as
if we received a ConfigureRequest which means that we must generate a
synthetic ConfigureNotify even if the window isn't moved or resized
from its current (initial) geometry.
During MetaWindow's x11/wayland split a slight behavior change for x11
windows crept in. Before the code split, MetaWindow->rect was
initialized with the X window's geometry, but now we're not
initializing MetaWindowX11Private->client_rect which causes the checks
for whether it's necessary to move/resize the window in
meta_window_x11_move_resize_internal() to tell us that we do need to
move/resize which means we do an XConfigureWindow() call and don't
send the sythetic ConfigureNotify. But since the X window isn't really
moving, the XConfigureWindow() call doesn't cause the X server to
generate a ConfigureNotify which breaks some clients such as Java's
AWT.
We can fix this by setting MetaWindowX11Privatew->client_rect for both
OR and non-OR windows. We can set buffer_rect for non-OR windows as
well to simplify the code since it will be assigned the correct value
in meta_window_x11_move_resize_internal() .

During xwayland initialization we run main loop and dispatch wayland
events, so that xwayland can initialize. If some client during this
phase connects and creates surface, mutter crashes because
it is not initialized yet. If we bind wayland socket after xwayland
is initialized and main loop is not running anymore, no client can
connect to mutter during initialization and that is what we want.

GDesktopTouchpadScrollMethod was used instead of GDesktopTouchpadClickMethod
which became visible now that the former has been removed from
gsettings-desktop-schemas.
https://bugzilla.gnome.org/show_bug.cgi?id=759304
When the touchpad is two-finger scrolling capable, always enable it.
When the touchpad only supports edge scrolling (usually older devices, and
usually smaller devices), allow disabling the edge scrolling.
This requires a newer gsettings-desktop-schemas as the scroll-method key
was removed, and the edge-scroll-enabled key added.

So that we can set it to 'check', and do configure-time discovery of the
dependencies, instead of enabling it explicitly.
This should make it easier to spot build issues on environments like
Continuous, which build Clutter and Cogl for running as part of the
display server infrastructure on Wayland.
We should allow a configuration file to set up the initial state of the
global state, which also implies being able to set the backend.
If the allowed backends have already been set programmatically via the
clutter_set_windowing_backend(), though, then the application code takes
precedence, as we assume that the application author knows better than
us what their code supports or requires.
The configuration file should set up the global state before we
initialize it; instead of relying on implicit ordering, explicitly read
the configuration file once, when creating the global shared context
data structure.
Like CLUTTER_DRIVER, we want to allow users to specify a list of
backends to test, and fall back to the internally defined priority as a
default.
This requires changing the way the allowed backend string is parsed,
both for the CLUTTER_BACKEND environment variable and for the
clutter_set_windowing_backend() function. Existing callers are still
supported with the exact same semantics.
Using environment variables only is not convenient for all platforms,
and in some cases it's beneficial to decide the default driver when
building Clutter. Cogl already has a similar configuration switch, and
since Clutter is overriding the default Cogl behaviour, it should offer
the same mechanism.
https://bugzilla.gnome.org/show_bug.cgi?id=742678
We have an hardcoded list of drivers we have to go through when creating
a Cogl context. Some platforms may expose those drivers, but not be the
preferred ones.
In order to allow users and system integrators to override the list of
drivers, we should crib the same approach used by GDK, and have an
environment variable with a list of drivers to try.
The new environment variable is called `CLUTTER_DRIVER` and accepts a
comma-separated list of driver names, which will be tested in sequence
until one succeeds. There's also an additional '*' token which is used
to ask Clutter to fall back to the internally defined preferred list of
drivers.

Wine removes the minimize func from its Motif hints on full-screen
windows, because, as the Win32 API literally says, the minimize button
is indeed not visible on full-screen windows.
Given that this code was added to prevent minimizing a panel by
accident, I don't necessarily think that it's relevant anymore.

Unsetting it in meta_display_handle_event() will make the pointer
emulation checks fail on TOUCH_END event handlers across clutter
actors, the sequence should still be considered as pointer emulating
at that time.
As we don't have a way to hook this post clutter event handling,
instead unset/reset it lazily on the next pointer emulating TOUCH_BEGIN
event, the checks would already fail on other sequences, even if the
pointer emulating touch ended earlier. The only extra thing we need
to take care about is sequence collision, at which point it's safe to
just unset the stored sequence if its new incarnation isn't flagged/
deemed as pointer emulating.

We enable a bunch of compiler flags to trip common errors during
development. While this is very useful while hacking on Clutter, it
makes the life of people building Clutter on automated build systems
much harder; thus, we should have a configuration option to opt out of
the -Werror business.
GNOME has pretty much standardised on `--disable-Werror`, so we should
crib that configure option.
The max potential number of logical monitors (i.e. MetaMonitorInfos)
is the number of CRTCs, not the number of outputs.
In cases where we have more enabled CRTCs than connected outputs we
would end up appending more MetaMonitorInfos to the GArray than the
size it was initialized with which means the array would get
re-allocated rendering invalid some MetaCRTC->logical_monitor pointers
assigned previously and thus ending in crashes later on.

Being able to select text and being able to edit text are two separate
capabilities, but ClutterText only allows the former with the latter.
The ClutterText:selectable property is set to TRUE by default, given
that it depends on the :editable property; this implies that all
ClutterText instances now are going to show a cursor as soon as they get
key focused. Obviously, this would make labels look a bit off — but if
you have a label then you would not give it key focus, either by
explicitly calling clutter_actor_grab_focus(), or by setting it as
reactive and allowing it to be clicked.
If this turns out to be a problem, we have various ways to avoid showing
a cursor — for instance, we could change the default value of the
selectable property, and ensure that setting the :editable property to
TRUE would also set the :selectable property as a side effect. Or we
could hide the cursor until the first button/touch press event. Finally,
we could always back this commit out if it proves to be too much of a
breakage for existing code bases.

Use the xdg_shell XML file installed by wayland-protocols instead of
our own copy. This protocol has yet to go through any unstable naming,
but since we had an outdated (though wire compatible) version, some
minor changes were needed.
https://bugzilla.gnome.org/show_bug.cgi?id=758633
Remove our own copy of the pointer gestures protocol, and us the one
installed by wayland-protocols. This also means the new fixed unstable
naming conventions are used for the new version of the protocol, which
is reflected in the change. No functional changes were made, it is only
a rename.

When running as a native compositor, we can just do that. However, the
previous code must stay for whenever it's run as a X11 client.
Additionally, the fallback switch{} that transforms clutter 1-indexed
buttons into input.h event codes had to be adapted to the change introduced
in clutter commit 83b738c0e, where the 4-7 button range is kept clear for
compatibility with the X11 backend.

On the wire, Wayland specifies the refresh rate in milliHz. Mutter sends
the refresh rate in Hz, which confuses clients, e.g. weston-info:
interface: 'wl_output', version: 2, name: 4
mode:
width: 2560 px, height: 1440 px, refresh: 0 Hz,
flags: current preferred
interface: 'wl_output', version: 2, name: 5
mode:
width: 3200 px, height: 1800 px, refresh: 0 Hz,
flags: current preferred
and xrandr:
XWAYLAND0 connected 2560x1440+3200+0 600mm x 340mm
2560x1440@0.1Hz 0.05*+
XWAYLAND1 connected 3200x1800+0+0 290mm x 170mm
3200x1800@0.1Hz 0.03*+
Export the refresh rate in the correct units. For improved precision,
perform the KMS intermediate calculations in milliHz as well, and
account for interlaced/doublescan modes.
This is also consistent with what GTK+ expects:
timings->refresh_interval = 16667; /* default to 1/60th of a second */
/* We pick a random output out of the outputs that the window touches
* The rate here is in milli-hertz */
int refresh_rate = _gdk_wayland_screen_get_output_refresh_rate (wayland_display->screen,
impl->outputs->data);
if (refresh_rate != 0)
timings->refresh_interval = G_GINT64_CONSTANT(1000000000) / refresh_rate;
Where the 'refresh_rate' given is exactly what's come off the wire.
1000000000/60000 comes out as 16667, whereas divided by 60 is ...
substantially less.
