If we rely on getting back an input event with the warped pointer
coordinates, we might draw a frame with the old coordinates if we warp
during the paint phase. Avoid that by moving the cursor immediately.

This patch adds support for confinement regions that are more complex
than a single rectangle. It relies on details about cairo regions not
explicitly in the API in order to generate the outer border of the
region.

The x/y coordinates of the ClutterInputDevice were not the ones which was
the result of this event but whatever event was queued the last. The
correct coordinates can, however, be found in the event itself, so lets
use those.

The wp_pointer_constraints protocol is a protocol which enables clients
to manipulate the behavior of the pointer cursor associated with a seat.
Currently available constraints are locking the pointer to a static
position, and confining the pointer to a given region.
Currently locking is fully implemented, and confining is implemented for
rectangular confinement regions.
What else is lacking is less troublesome semantics for enabling the lock
or confinement; currently the only requirement implemented is that the
window that appears focused is the one that may aquire the lock.
This means that a pointer could be 'stolen' by creating a new window that
receives active focus, or when using focus-follows-mouse, a pointer
passes a window that has requested a lock. This semantics can be changed
and the protocol itself allows any semantics as seems fit.

In order to reuse some vector math for pointer confinement, move out
those parts to its own file, introducing the types old types
"MetaVector2" and "MetaLine2" outside of meta-barrier-native.c, as well
as introducing MetaBorder which is a line, with a blocking direction.

Add support for sending relative pointer motion deltas to clients who
request such events by creating wp_relative_pointer objects via
wp_relative_pointer_manager.
This currently implements the unstable version 1 from wayland-protocols.

The code currently implements a function, get_time, that
fetches a timestamp. That duplicates code already in glib,
and the glib implementation is better, anyway, since it doesn't
skew backward when the system clock is changed.
This commit changes the code to use g_get_monotonic_time and
drop the get_time function.

Instancing a gbm device without initializing EGL with it means that it
won't be able to import wl_drm buffers. Instead, let's re-use cogl's
gbm device which is already properly initialized.

GTK+ paints some elements like box shadows (which Adwaita likes to (ab)use
for borders) outside the rectangle passed to gtk_render_*. This is not
an issue if our own invisible frame border is big enough, but in case
of non-resizable windows we end up clipping away part of the decoration.
Use the newly added gtk_render_background_get_clip() to make sure we
always use a mask that is large enough to contain all decorations.

Use global theme variant only if window does not have _GTK_THEME_VARIANT
property. This allows applications to request default theme variant when
global dark theme is enabled.

commit 0165cb6974 changed
mutter to release committed shm buffers as soon as they were
uploaded to the GPU.
It also inadvertently changed mutter to prematurely
release EGL buffers (which never get copied, but get used
directly).
This commit corrects that mistake.

When a client is ready for the compositor to read a surface's
shared memory buffer, it tells the compositor via
wl_surface_commit.
From that point forward, the baton is given to the compositor:
it knows it can read the buffer without worring about the client
making changes out from under it.
After the compositor has uploaded the pixel contents to the video
card it is supposed to release the buffer back to the client so that
the client can reuse it for future use.
At the moment, mutter only releases the buffer when a new buffer
is attached. This is problematic, since it means the client has
to have a second buffer prepared before the compositor gives the
first one back. Preparing the second buffer potentially involves
copying megabytes of pixel data, so that's suboptimal, and there's
no reason mutter couldn't release the buffer earlier.
This commit changes mutter to release a surface's buffer as soon
as it's done processing the commit request.

GTK+ improved its CSS support, and the default theme started to make
use of it, so we must update our theming code accordingly. Add support
for margins where they make sense.
GTK+ improved its CSS support, and the default theme started to make

supporting min-width/min-height where it makes sense.
Since we are using the surface actor to draw the DND icon, the offset
is already accounted for by MetaSurfaceActorWayland, and passing the
surface position offset would effectively double the actual offset,
causing the icon to be misplaced.
This patch always sets the anchor offset to (0, 0) when the icon is a
Wayland surface, and lets the surface actor deal with the offsetting.

We now additionally send:
- wl_data_offer.source_actions
- wl_data_source.action
- wl_data_offer.action
- wl_data_source.dnd_drop_performed
- wl_data_source.dnd_finished
The protocol changes allow for compositors to implement different policies
when chosing the action, mutter uses this to reimplement the same behavior
that GTK+ traditionally had:
- Alt/Control/Shift modifiers change the chosen action to
ask/copy/move respectively
- Drags with middle button start out as "ask" by default
As mutter now also grabs the keyboard and unsets the window focus for these
purposes, the window focus is restored after the drag operation has
finished.
The Xdnd bridge code is also modified to cope with actions, so mixed
wayland-x11 scenarios are able to convey that information.

This will be useful during DnD, where mutter is expected to consume
keyboard events for either allowing changes in the selected DnD action,
or misc a11y features like keyboard-driven DnD.
Currently, the vtable contains 2 functions, key() will be used on every
key event we get from Clutter, modifiers() will notify of changes in the
keyboard modifiers (mouse buttons will never be set in the modifier mask)

As per the spec:
- wl_pointer.axis_source determines the current source of
scroll events.
- wl_pointer.axis_stop determines when there's no further
scroll events on the given axis.
- wl_pointer.axis_discrete is emitted on "wheel"
scroll sources, measured in ticks.
- wl_pointer.frame is meant to coalesce events that logically belong
together, e.g. axis events in this case.

Some of the mutter code using these properties expects them to be
null-terminated whereas xcb does not use null-terminated strings:
http://xcb.freedesktop.org/XcbRationale/
This was in some cases resulting in the WM_CLASS property containing
garbage data which broke application matching, caused the hot-corner and
window-switcher to stop working, or was exposed as text in the UI.

This fixes an issue analogous to bug 760330 for the X11 backend,
except on this backend we wouldn't crash accessing free'd memory.
Instead we're leaking watches since we steal them from the hash table
which means that when they're removed in
_meta_idle_monitor_watch_fire() they're no longer there and thus
they're never free'd.
https://bugzilla.gnome.org/show_bug.cgi?id=760476
Right now the XSync based idle monitoring code, will fetch all active
watches into a list, and then call their watch callbacks one by one
as necessary. If one watch callback invalidates another watch, the
list will contain free'd memory.
This commit makes sure to consult the hash table after ever call
of a watch callback, to ensure mutter never looks at freed memory.
Fixes crash reported on IRC by Laine Stump with his synergy setup.

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.
