Clutter discards any motion event if next event happens to also be a
motion event. This is problematic when the motion event carries
relative motion deltas, since the information about them is completely
lost.
Until we have moved away made the stage stop discarding motion events,
lets work around the issue by compressing them, effectively adding
multiple relative motion deltas together, would one be discarded.

If a client would attach a buffer to a surface, commit, destroy the
buffer and then later set the surface as a cursor, there will be no
wl_buffer available to be used by the cursor role. Instead of
dereferencing the non-existing wl_buffer resource, handle this situation
by logging a warning and treating a prematurely destroyd wl_buffer as if
no buffer had been attached.

Not having a surface actor would cause the window actor state to be
considered frozen, thus causing various state (such as geometry, shape
etc) synchronization to be delayed until thawed. If the window actor
was "thawed" due to having a surface set, not all state would be
properly synchronized, causing the thawed window actor to be displayed
incorrectly.
This patch fixes this by putting state synchronization after thawing in
a common function, calling it both from frozen count decreasing and
surface setting.
This fixes for example misplaced menus in Steam.

The rectangle passed to capture_view() is in stage coordinate space;
thus, to translate to framebuffer coordinate space, the origin need to
be translated by the view layout position.
This fixes capturing views not at position (0, 0).

Implement min/max size request from xdg-shell-v6 and plug it into the

The seat capability updating is synchronous, but input events are
asynchronous (first queued then emitted). This means we may end up in a
situation where we from libinput first may receive a key event,
immediately followed by a device-removed event. Clutter will first
queue the key event, then remove the device, immediately triggering the
seat capability removal.
Later, when the clutter stage processes the queued events, the
previously queued key event will be processed, eventually making it
into MetaWaylandSeat. Before this patch, MetaWaylandSeat would still
forward the key event to MetaWaylandKeyboard, even though it had
'released' it. Doing this would cause referencing potentially freed
memory, such as the xkb state that was unreferenced when the seat
removed the capability.
In order to avoid processing these lingering events, for now, just drop
them on the floor if the capability has been removed.
Eventually, the event queuing etc needs to be redesigned to work better
when used in a Wayland compositor, but for now at least don't access
freed memory.

When a modal transient is unmanaging, most likely the parent of the
modal transient should be focused.
In Wayland, a MetaWindow is created when a shell surface role (like
xdg_toplevel) is created, but a window cannot be shown until a buffer
is attached. If a client would create two modal transients and make
them both have the same parent, but only one get a buffer attached
(i.e. shown), when unmanaging the modal transient that was showing,
when finding a new focus candidate, the stacking code will ignore the
not-to-be-shown buffer-less modal transient when finding a good
candidate for focusing. In the case described here, this means it will
find the parent of the unmanaging modal transient.
This newly chosen candidate will then be passed to meta_window_focus();
meta_window_focus() will then try to find any modal transient to focus
instead, will find the one without any buffer, then fail to focus it
because it cannot be mapped, thus making meta_window_focus() not focus
anything. Since meta_window_focus() didn't change any focus state, the
assert in meta_window_unmanage() checking that the unmanaging window
isn't focused anymore will be hit, causing mutter to abort.
For now, fix this by checking whether the modal transient can actually
be focused in meta_window_focus(). For X11 client windows, a window
will be defined to be focusable always, but for Wayland client windows,
a window will be determined focusable only if it has a buffer attached.
In the future, we should probably do a more thorough refactorization of
focus handling to get rid of any X11 - Wayland differences.

We may be assigned multiple times, if the surface is assigned to be a
cursor surface multiple times. Each time e.g. wl_pointer.set_cursor is
called, we'll be assigned.
While the role object exists, we'll handle buffer use count even when
we are not actively assigned, thus we should only handle the initial
assignment use count bump when constructing, so that we don't increase
it when reassigned, where the wl_resource may already have been
released.

For backend handled cursors, if nothing else changes on the clutter
stage, we end up not sending out frame callbacks since clutter doesn't
draw a new frame.
To fix this, we'll keep cursor surfaces' frame callbacks separate from
other surfaces' and trigger them from the new
MetaCursorRenderer::cursor-painted signal which handles both software
and hardware cursors.
https://bugzilla.gnome.org/show_bug.cgi?id=749913
This signal allows interested parties to be notified of a new cursor
frame being painted regardless of whether it's being painted by the
backend directly or if it's a software rendered cursor frame handled
by clutter.

Absolute pointer events used the X coordinate as both X and Y. This

Even without a compositor grab, key events may still be expected to
be processed by the compositor and not applications, for instance
when using ctrl-alt-tab to keynav in the top bar. On X11, focus is
moved to the stage window in that case, so that events are processed
before they are dispatched by the window manager. On wayland, we need
to handle this case ourselves, so make sure to not pass key events to
wayland in that case, and move the key focus back to the stage when
appropriate.

The WL_bind_wayland_display spec says that EGL images should be created
using EGL_WAYLAND_BUFFER_WL as the target and a NULL context. Mesa
seems to be lenient and accept any context, however some other stacks
aren't so forgiving and fail if anything apart from EGL_NO_CONTEXT is
used.

Switch to the output naming logic used by the X server's modesetting
driver which, in particular, uses drmModeConnector's connector_type_id
instead of connector_id.
The kernel generates new connector_id's every time there are changes
which means we can't identify the same monitor on the same connector
after an hardware hotplug. Switching to connector_type_id fixes this.

If cogl fails to create a texture from the client's given buffer,
mutter would raise a fatal error and terminate.
As a result, a broken client might kill gnome-shell/mutter and take the
entire Wayland session with it.
Instead of raising a fatal error in this case, log the cogl error
message and send the client an OOM error, so mutter/gnome-shell can
survive an unsupported buffer size.

For some reason, when a modal dialog was made an attaching
transient-for, if the window wasn't "constructing", it would be
unmanaged and rely on some side effect to be recreated. This side
effect is not triggered for Wayland clients, thus if one happen to set
a surface as "modal" via gtk_surface.set_modal before
xdg_toplevel.set_parent, it'd be unmanaged and never show up.
Instead, simply just set the tranciency anyway for Wayland clients.
This makes GTK+ clients that set_modal() before set_transient_for()
work.

Windows from Xwayland still needs to use the Wayland path, but is
represented an MetaWindowX11, thus the abstraction introduced in
"window: Make meta_window_has_pointer() per protocol implemented"
is wrong. Lets turn back time, and reconsider how this can be
abstracted more correctly in the future.
This reverts commit 9fb891d216.
Rely on the actor surface role's commit function for queuing frame
callbacks. This also makes the surface actor state synchronization work
again, which was broken by 'wayland: Sync surface actor state in actor
role commit handler'.

Don't check whether the surface of the role has a window, but whether
the corresponding toplevel surface has a window. This is necessary to
make subsurfaces not always early out.
https://bugzilla.gnome.org/show_bug.cgi?id=770131
There is nothing stopping a subsurface from commiting its state before
its parents role has been assigned. Thus, we need to handle
meta_wayland_surface_get_toplevel() returning NULL for subsurfaces even
on commit.
Make sure to always call the parent role commit vfunc, so that they can
handle updating their state properly.
This means other places need to handle the situation where
surface->window is NULL on commit. This may for example happen when the
parent of a modal dialog is unmapped or NULL is attached to a
wl_shell_surface.

Port the xdg_shell implementation to use the unstable v6 protocol. This
includes:
- making xdg_surface a generic base interface for xdg_shell surface
roles
- create a xdg_toplevel role replacing the old xdg_surface
- change the xdg_opup role to be based on xdg_surface
- make xdg_popup not grab by default
- add support for xdg_positioner
