The new tiling code, instead of based around "tiling states", is instead
based around constrained edges. This allows us to have windows that have
three constrained edges, but keep one free-floating, e.g. a window tiled
to the left has the left, top, and bottom edges constrained, but the
right edge can be left resizable.
This system also is easily extended to support corner tiling. We also,
using the new "size state" system, also keep normal, tiled, and
maximized sizes independently, allowing the maximize button to bounce
between maximized and tiled states without reverting to normal in
between. Dragging from the top will always restore the normal state,
though.

We can know the rotation modes supported by the driver, so
export these as our supported modes, and ensure these modes
are honored on the CRTC primary plane upon apply_configuration().
It is worth noting however that not all hardware will be
capable of supporting all rotation modes (in fact, most of
them won't). A driver independent solution should be in
place to back up the rotation modes unsupported by the
drivers, so this is still a partial solution.
The cursor renderer has also been changed to default to
software-based rendering anytime the cursor enters a
rotated CRTC. Another solution would be actually rotating
the DRM cursor planes, but then it requires applying rotation on
these per-CRTC, and actually transforming the pointer position by
the output matrix. This brings marginal gains, so we use the
"sw" rendered cursor, which will be transformed together with
the primary plane.

In case a window is hidden when we're ordered to make it transient to
a different parent we must re-evaluate its visibility status or we'll
get into an inconsistent state where the parent is visible and the
child isn't.

This seems like a more generally useful and intuitive behavior. Note
that, in X sessions, this is what already happened in practice since
meta_display_begin_grab_op() calls meta_window_grab_all_keys() which,
on X11, does meta_window_focus().

This is a really old behavior introduced in commit
585e362526 which is inconsistent since
it only applies to SSD windows.
If we really want this, we should focus the window elsewhere so that
it applies consistently to all windows.

Some applications, like Chromium, explicitly set their bounding region
to the client area when full-screen. Detect this case, and allow us to
fullscreen when this happens.
Don't update the stack until after setting the window->transient_for
field. Updating before will cause the stack transient-for constraint to
be missing until the next time constraints are applied.

The test runner sends a "show" command to the test clients and assumes
this was enough work done by the client to enable the compositor to map
the window. Now that we wait to show a Wayland window until the first
buffer is attached (see bug 750552), we need to make sure that we attach
a buffer before assuming that we have the final stacking order.
So, to in order to continue relying on "show" to be enough to actually
show a window, let the test client wait until it has drawn the first
frame.
This makes the tests using Wayland clients test non-flaky.

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.
