If a queued event is being processed after the surface is
destroyed, trying to access the window associated with the surface
will lead to a segmentation fault.
This patch avoids the crash by first checking if the surface is not null.

This fixes build error caused by commit 614d6bd. We can simply remove
the usage of meta-wayland.c functions in non-wayland build because
META_BACKEND_X11_MODE_NESTED is only used in wayland.

When running on wayland, we might have our own subsurface
desynchronized from the foreign GdkWindow. It is important that we
report the size of the actually surface we're rendering to, otherwise
the logic in ClutterStage might discard resize operation that
resynchronize the subsurface with the stage's size.
https://bugzilla.gnome.org/show_bug.cgi?id=754697
For foreign windows this should be dealt with by the embedding
framework. In particular on Wayland with foreign windows, we might
want to create a subsurface and use the foreign window only for events
and frame clock synchronization.
https://bugzilla.gnome.org/show_bug.cgi?id=754697
Some operations like :
* resize
* show/hide
* set_title
* set_user_resizable
should be handled by the embedding framework, so disable them for
foreign windows.

When using Clutter embed inside a Gtk application, a stage might end
up realized but not visible. In this case we might discard doing any
kind of animation processing.

On Wayland deinit() of an onscreen buffer is going to destroy the
associated native window of an EGLSurface. So we should destroy the
EGLSurface as well otherwise we might end up confusing the GL driver.
We also currently guard against setting a EGL_NO_SURFACE as current
EGLSurface, but this shouldn't be a problem if we have a surfaceless
context. So we allow surface destruction under that condition.

Use a better name, use GNOME conventions for error handling, open code the
client error reporting and send the error to the correct resource.
wl_subcompositor doesn't have a role error yet, so continue use some
other error. The only effect of this is error received in the client will
be a bit confusing, it will still be disconnected.

Just like GtkGrid, changing the orientation of a ClutterGridLayout does
not change the existing layout; the orientation property is only used as
a hint when adding new children.
If the user switches VTs in the middle of a page flip, the
page flip operation may fail with EACCES. page flipping will
work next time the VT becomes active, so we shouldn't disable
page flipping in that case.

If cogl fails to open the drm device, initialize gbm, or open the
egl display, then it closes the drm fd, uninitializes gbm, closes the
display and then calls _cogl_winsys_renderer_disconnect which does
most of those things again, on the, now deinitialized, members.
This commit removes the explicit failure handling in renderer_connect and
defers cleanup to disconnect.

gbm confusingly has two different format types, and cogl
is using the wrong one in some of its calls to gbm_surface_create
This commit fixes the calls that are wrong.

Older GCC only allows "for (int i" in explicit c99 mode - there's probably
no reason that we can't enable that, but avoiding the construct for
a fast fix.
If the user Alt-Tabs out of the window, we will be left thinking
the Alt key is still pressed since we don't see a release for it.
Solve this and other related issues for the nested X11 compositor
by selecting for KeymapStateMask which causes a KeymapNotify event
to be sent after each FocusIn, and when we get these events, update
the internal XKB state and send any necessary modifiers events to
clients.

Some backgrounds don't fully fill the screen. For those backgrounds
it's important to paint a color behind them to fill in the gaps.
This commit checks whether or not the background image textures take
up the entire monitor, and in the event they don't, draws a color
behind them (such as it would do if the background were
translucent).
https://bugzilla.gnome.org/show_bug.cgi?id=754476
meta_background_get_texture only draws the bottom image texture
if
1) the blend factor leaves the top image translucent
or
2) the top image is translucent from alpha
The latter case doesn't actually matter since we're using REPLACE
on the top image texture.
This commit drops the unnecessary check for the second case and
applies demorgans law to the conditional for clarity.

We automatically switch the request mode of the container depending on
the GridLayout's orientation, but we need to keep track of the request
mode during allocation, so that we don't get out of sync if the user
changed the request mode after adding the layout manager.
This change also brings us closer to the code in GtkGrid.
We use the orientation of the grid to get the preferred size of the
layout, but we should be using the orientation of the request instead.
The preferred width has an orizontal orientation, and the preferred
height has a vertical orientation.
This allows us to refactor the get_preferred_* implementation into a
separate function.
There were lots of code handling the native renderer specific cases;
move these parts to the renderer. Note that this causes the X11 case to
always generate the texture which is a waste of memory, but his
regression will be fixed in a following commit.
The lazy loading of the texture was removed because it was eventually
always loaded anyway indirectly by the renderer to calculate the
current rect.

There is nothing special about the private API which only consists of
getters for renderer specific backing buffer. Lets them to the regular
.h file and treat them as part of the normal API.
