This is necessary to avoid a deadlock with the compositor. When setting
a stage size before the stage was shown this would trigger a redraw
inside clutter_stage_wayland_resize. This redraw would result
in a call into eglSwapBuffers which would attach a buffer to the surface
and commit. Unfortunately this would happen before the role for the
surface was set. This would result in the compositor not relaying to the
client that the desired frame was shown.
With this change the call to wl_shell_surface_set_toplevel is always
made before the first redraw.

We should not create a shell surface and set the role for that shell
surface if the surface was a foreign one provided through
clutter_wayland_set_wl_surface
https://bugzilla.gnome.org/show_bug.cgi?id=699578
This adds support for optionally a providing a foreign Wayland surface
to a ClutterStage before it is first show. Setting a foreign surface
prevents Cogl from allocating a surface and shell surface for the stage
automatically.

v3: set a boolean to indicate that this stage is using a foreign surface

This allows the integration of Clutter with another library, like GTK+,
that is dispatching the events itself. This is implemented by calling
into the cogl_wayland_renderer_set_event_dispatch_enabled() and since
that function must be called on the newly created renderer the newly
added clutter_wayland_disable_event_retrieval must be called before
clutter_init()

Since commit 4543ed6ac3 in Cogl, Cogl will now try to consume
Windows message itself. This doesn't really cause any problems because
both message loops just call DispatchMessage which will cause the
message to be routed through Clutter's window procedure either way.
However, it's not great to have two sources listening for messages so
this patch disables Cogl's message retrieval.
https://bugzilla.gnome.org/show_bug.cgi?id=701356
This removes a bit of work that we have to do for every device, and makes it
easy for mutter to patch out parts of the event mask it doesn't want.

The Wayland 1.0 API allows orthoganal components of an application to
query the shell and compositor themselves by querying their own
wl_registry. The corresponding API in Cogl has been removed so Clutter
shouldn't call it anymore.
https://bugzilla.gnome.org/show_bug.cgi?id=703878
The Wayland server API has changed so that wl_shm_buffer is no longer
a type of wl_buffer and wl_buffer will become an opaque type. This
changes ClutterWaylandSurface to accept resources for a wl_buffer
instead of directly taking the wl_buffer so that it can do different
things depending on whether the resource points to an SHM buffer or a
normal buffer. This matches similar changes to Cogl:
https://git.gnome.org/browse/cogl/commit/?id=9b35e1651ad0e46ed48989https://bugzilla.gnome.org/show_bug.cgi?id=703608
Cogl 1.16 has deprecated a lot of API which it will be difficult for
Clutter to catch up with. For the time being the warnings are just
being disabled to keep the build output clean.

There is no reasonable use case for having the functions, the virtual
functions, and the signals for realization and unrealization; the
concept belongs to an older era, when we though it would have been
possible to migrate actors across different GL contexts, of in case a GL
context would not have been available until the main loop started
spinning. That is most definitely not possible today, and too much code
would utterly break if we ever supported that.
The majority of Clutter input events require a time so that that the
upper levels of abstraction can identify the ordering of events and also
work out a click count.
Although some Wayland events have microsecond timestamps not all those
that Clutter expects do have. Therefore we would need to create some
fake times for those events. Instead we always calculate our own time
using the monotonic time.

If we allow content repeats on the texture nodes, then we need to use
the "automatic" wrap mode for the texture layer in the pipeline, instead
of the clamp-to-edge one.

Windowing system features we need are not mapped on cogl_has_feature().

Cogl (as of 0b2b46ce) now only sets the shell surface as toplevel when
the CoglOnscreen is shown.
Without calling wl_shell_surface_set_toplevel the compositor will not
know what role to give to the compositor and thus the stage will not
appear.
When we look to support multiple roles / foreign surfaces we will need
to revisit this call and ensure we only call it when we are working in
the default case.
https://bugzilla.gnome.org/show_bug.cgi?id=703188
Since Cogl also polls on this file descriptor we can get into situations
where our event source is woken up to handle events but those events
have instead been handled by Cogl resulting in the source sitting in
poll().
We can safely rely on Cogl to handle the polling on the event source and
to dispatch those events.

When the cursor visibility changes, we have to relayout the ClutterText
actor instead of just redrawing it - as the cursor changes the
PangoLayout size, a size request cycle is needed.
https://bugzilla.gnome.org/show_bug.cgi?id=702610
While we still don't want to perform implicit transitions on unmapped
actors, we can relax the requirement on having been painted once; the
was_painted flag was introduced to avoid performing implicit transitions
on the :allocation property, but for that we can use the
needs_allocation flag instead, as needs_allocation will be set to FALSE
when we have been painted as well.
Thus, we retain our original goal of not having actors "flying" into
position on their first allocation, without the side effect of
preventing animations when emitting the ::show signal.
When setting the font using clutter_text_set_font_description(), the
font settings on a ClutterText actor can be reset when there is a dpi
changes signaled by the backend.

1ddef9576d87c98fafbcefe3108f04866630c2cd had its logic the
wrong way round, a gesture should begin as soon as the requested number
of touchpoints is reached. Correcting this fixes tap events
https://bugzilla.gnome.org/show_bug.cgi?id=700980
When we changed the MetaGroup to handle internal effects, we updated
has_effects(), but forgot to fix the equivalent has_constrains() and
has_actions() method.
Now, if we clear the constraints or the actions on an actor, and we
call has_constraints() or has_actions(), we get an false positive.
When using a ClutterOffscreenEffect, the size of the offscreen buffer
allocated to perform the effect is currently computed using the paint
volume of the actor it's attached to and in the case the paint volume
cannot be computed, the effect falls back to using the stage's size.
If you scale an actor enough so its paint volume is much bigger that
the size of the stage, you can end up running out of memory (which
leads to your application crashing).
