Until now we only supported direct scanout to the primary plane if the
buffer size perfectly matched the display size.
Since display controllers usually support scaling and cropping buffers
highly efficiently, try to let them do the job. This is usually helpful
if wp_viewporter is used by the client or Mutter uses fractional
scaling.
This has several advantages:
- Games (e.g. SDL2 based ones) can almost always hit direct scanout
paths in fullscreen mode. Notably when fractional scaling is used or
the game renders in a non-native resolution (or both).
- Video players using YUV buffer formats and wp_viewporter can easily
hit direct scanout paths, making displaying video very power
efficient as the 3D engine is not used at all.
Note that this still only uses the primary plane, no overlay or underlay
planes, making this change comparatively low risk.

In a following commit we will start supporting scaled and croped
surfaces, thus, in preparation, update the logic to three common cases:
1. only one surface, fullscreen (most apps)
2. a content surface and a black background surface which the client
does not want to unmap, fullscreen
3. top-level subsurface covers the whole window and is opaque (Firefox)
The remaining currently supported cases should be fairly uncommen and
and harder to compute.
Note that we already check that the window cover the stage view in
MetaCompositorView.

This allows us to pass on the related data from CoglScanouts.
If dst_rect does not match the mode, we assume that not covered areas
are opaque black - usually black bars around a centered surface.
While such driver behaviour does not appear to be documented (well) yet,
it seems to be followed by all known existing drivers and is used in a
similar way in ChromeOS.

We need an object to hold additional scanout related information, such
as scaling and positioning data. Turn CoglScanout into such an object,
moving the interface into CoglScanoutBuffer.

Except meta_window_x11_get_group, which is still used by GNOME Shell
and we can't make it a private API for now.
Will need further investigation and could be done as a future
step

The macro used to call into a bunch of other macros so let us turn it
into a single function.
This would simplify things for the next commit that puts the MetaGroup
usage behind a X11 ifdef

If such a failure is followed by a successful frame then the Cogl frame
queue would have size 2, leading to an assertion failure in
`meta_onscreen_native_notify_frame_complete`:
```
g_assert (!cogl_onscreen_peek_head_frame_info (onscreen));
```
Notifying on the failure however keeps the Cogl frame queue limited to
a size of 1 and we recover gracefully with only a missed frame and a
warning message.

Popups were missing the "input focus" unification in the pointer
seat, triggering MetaWaylandKeyboard focus changes underneath. On
one hand this missed moving all associated focus with it, on the
other hand this made keyboard and global input focus get out of
sync, and bring funky behavior like keyboard focus loss after
dismissing popups.

In some circumstances, we may end up with outputs with the same
vendor/product/serial, in which case we have a hard time finding the
right one to map tablets to, since configuration only has these 3
pieces of data.
Add the handling of a 4th argument containing the output name
based on the connector (e.g. HDMI-1), so that it can be used to
disambiguate the output if necessary.
This only kicks in if there actually are multiple outputs with the
same EDID data. A goal of the configuration as it was stored was to
remain useful if the user changed how the device is physically
connected to the computer, this remains true for the vast majority
of users having a single thing of each.

Our hashtable stores tools by the serial but our stylus tool and eraser
tool share the same serial - they only differ by the tool type.
This results in only one tool being created and this tool re-used for
the other type tool. Fun side-effects of this are that the stylus ends
up using the eraser pressure curve (or vice versa).
Hack around this by bit-flipping the serial for the eraser to
make it distinct - this is the only place we need to wrorry .

For barrier validation, check_barrier() would start from the
(presumably) left-most monitor and walk the neighbor monitors to the
right.
This is assuming that there is always a monitor at (0.0), which is not
necessarily the case. If the first monitor on the left is not aligned at
the top, there is no logical monitor at (0.0) causing a NULL pointer
derefence.
Instead of starting from the monitor at (0,0), start from the primary
logical monitor, as there is necessarily one.

There doesn't seem to be a good reason to keep this code in
`MetaWaylandSurface`. Moving it to `MetaWaylandBuffer` cleans things
up and will allow us to tread buffers differently depending on their
type.

For secondary GPU rendering contexts we currently might choose an EGL
config with a format which is not supported on all primary planes. The
renderer is created when a GPU is detected and lighting up outputs and
thus assigning CRTC and primary planes can happen at any point after
that. This means we have to make sure that all possible plane
assignments will work with the rendering context when we create it.

It can be used to force a specific RGB range. Some monitors don't follow
the specification and expect a signal different from what we send. This
property allows to force a mode which hopefully then works correctly for
the sink.
