Firstly, this patch makes MetawaylandDataSource a GObject. This is in
order to easier track its lifetime without adding destroy signals etc. It
also makes the vfunc table GObject class functions instead while at it,
as well as moves protocol specific part of the source into their own
implementations.
An important part of this patch is the change of ownership. Prior to this
patch, MetaWaylandDataDevice would kind of own the source, but for
Wayland sources it would remove it if the corresponding wl_resource was
destroyed. For XWayland clients it would own it completely, and only
remove it if the source was replaced.
This patch changes so that the protocol implementation owns the source.
For Wayland sources, the wl_resource owns the source, and the
MetaWaylandDataDevice sets a weak reference (so in other words, no
semantical changes really). For XWayland sources, the source is owned by
the selection bridge, and not removed until replaced or if the client
goes away.
Given the changes in ownership, data offers may now properly track the
lifetime of a source it represents. Prior to this patch, if an offer with
an XWayland source would loose its source, it wouldn't get notified and
have an invalid pointer it would potentally crash on. For Wayland
sources, an offer would have a weak reference and clean itself up if the
source went away. This patch changes so the behavior is consistent,
meaning a weak reference is added to the source GObject so that the offer
can behave correctly both for Wayland sources and XWayland sources.

When a possible drag dest client crashes during DnD, it may happen
we receive first the destroy notification for the data_device, and
later the notification for the focus surface. When this happens we
unset the drag_focus_data_device first, and later on
meta_wayland_drag_grab_set_focus(grab, NULL) we assume it still
exists when sending the leave event, leading to mutter crashing
right after.
So, as we don't receive any ordering guarantees about resource
destruction, just prepare the meta_wayland_drag_grab_set_focus()
paths for this.
It seems that fglrx sometimes gives us absolute junk when requesting the
outputs, and if we don't trap errors, we'll just crash when trying to
configure a junk output. Use xcb so errors simply get ignored.
For enter / leave events, which we use in the UI code, we need to make
sure that these coordinates are root-relative as well, otherwise the
cursor when entering frames might be incorrect.
Going from fullscreen to unfullscreen involves a frame border size, so
in order to properly interpret the saved rect size, we need to make sure
that the frame borders are fully up to date.
When we're unredirected, we don't have a pixmap, and thus our allocation
becomes 0x0. So when events come in, they pass right through our actor,
going to the one underneath in the stack.
Fix this by having a fallback size on the shaped texture actor when
we're unredirected, causing it to always have a valid allocation.
This fixes clicking on stuff in sloppy / mouse mode focus.
In commit cc5def1, buttons were changed from GdkRectangles to
MetaButtonSpace units, but the corresponding memset hack was not.
This means that the clickable portion of the unshade rectangle
was always set to uninitalized memory. The effects of this were
random, but in cases where the moon is aligned just right, the
rectangle would graze over the borders, and so it would take priority
over other borders and show a pointer cursor instead of a resize
cursor.
Since we're using xcb now, not Xlib, it doesn't have the stupid silly
thing where it copies all 32-bit data to 64-bit data to match the
long-y-ness of it.
It seems the largest possible value is to be passed, so actually pass
that instead. Note that even though the name of the xcb_get_property
parameter is called 'long_length' its actually a uint32_t.

If a client unsets a selection (calls set_selection with the offer
NULL), this should cause the compositor not to continue sending the
previously set offer.

If we're running as a nested compositor, we must not attempt to
passive grab on the root window, and we should be setting the
touch event mask on the stage window.

The "calc showing" operation is queued in a few places alongside MetaWindow
creation, we should be ignoring these until there is a buffer to show.

Mutter generates a motion event for every button and scroll events,
which confuses Xwayland apps that rely on XMotionEvents for various
purposes, e.g. it fools rxvt jumpy mouse detection code.
Remove the call to notify_motion() from the button and scroll event
handlers to avoid these spurious motion events.

This way, we won't be hit with BadValue errors if we set it to a value
outside the X device's range. This can happen for touchpads without
two-finger scrolling, for instance.
Certain crossing modes notify about synthesized events, where
the pointer didn't really leave the window. Unsetting the stage
from the device at that time is incorrect, and will leave all
remaining touches unable to pick coordinates, so silently eaten
away.

Straight from Cogl.
This allows us to propagate the GdkVisual Cogl and Clutter use to
embedding toolkits, like GTK+.
The function is annotated as being added to the 1.22 development
cycle because it will be backported to the stable branch, so that
downstream developers can package up a version of Clutter that does
not crash on nVidia.

GDK 3.16 started selecting different visuals, to best comply with the
requirements for OpenGL, and this has broken Clutter on GLX drivers that
are fairly picky in how they select visuals and GLXFBConfig.
GDK selects GLXFBConfig that do not include depth or stencil buffers;
Cogl, on the other hand, needs both depth and stencil buffers, and keeps
selecting the first available visual, assuming that the GLX driver will
give us the best compliant one, as per specification. Sadly, some
drivers will return incompatible configurations, and then bomb out when
you try to embed Clutter inside GTK+, because of mismatched visuals.
Cogl has an old, deprecated, Clutter-only API that allows us to retrieve
the XVisualInfo mapping to the GLXFBConfig it uses; this means we should
look up the GdkVisual for it when creating our own GdkWindows, instead
of relying on the RGBA and system GdkVisuals exposed by GDK — at least
on X11.
