If there is no laptop panel (for example on a desktop PC or a virtual
machine), attempting to put a NULL monitor in the list of matches
will just make mapping_helper_apply() crash.

It's enabled by default when using the i915 driver, but disabled
everywhere else until it can be made reliably an improvement. Until
then, for anyone want to force-enable it, add the string
'dma-buf-screen-sharing' to the experimental features list in GSettings.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1442
Seems DMA buffer based interprocess buffer sharing is more broken than
not, so for now only enable it when using the i915 driver.
For example vmwgfx, qxl and radeon, it results in mmap() failing to mmap the
memory region. Other drivers, e.g. amdgpu will function, but may hit
very slow memory download paths, resulting in worse performance.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1442
When the CoglRenderer didn't set the DMA buffer constructor vfunc, we
return NULL. What we didn't do was set the error, meaning the caller
would crash if it tried to look up why DMA buffer construction failed.

We only want the panel autorotation to happen if the laptop has an
accelerometer, and is in tablet mode. Regular laptop mode should
lock the orientation, and let it be configured manually.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1311
So far, we've expected this signal to not happen whenever autorotation
shouldn't apply (no accelerometer is a strong reason). In future commits
we'll add further checks to this policy, so prevent autorotation to
change the display configuration if the MetaOrientationManager signal
happens but it should be ignored.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1311
Instead of having everyone check net.hadess.SensorProxy themselves, have
this all controlled by the MetaOrientationManager, and proxied everywhere
else via a readonly property in org.gnome.Mutter.DisplayConfig.
We want to attach more complex policies here, and it seems better to
centralize the handling of the autorotation feature rather than
implementing policy changes all over the place.

We used to pick the "best" output for each builtin/size/edid categories,
and then pick the "best" (in that order) of those for each input device.
This is most often enough, but is prone to wrong results in some corner
cases (eg. 2 outputs with the exact same dimensions).
Change this to a score mechanism that doesn't leave outputs out. The
weights are the same, but the score is accumulated if an output matches
multiple categories. All outputs are evaluated and sorted by score, and
input devices with the best matches are applied first (as they already
did).
This should break the tie if eg. there's 2 outputs with similar dimensions,
but one of them has some EDID match in addition. The output with multiple
matches will score higher up, while it might have been entirely discarded
with the previous implementation.

The work at https://gitlab.gnome.org/GNOME/gnome-control-center/issues/239
intended to make integrated devices optionally mappable to other outputs
(in order to allow fix mishandling from our heuristics, or to quickly reach
things in other monitor without changing devices).
This was missed in that plan, we do allow cycling outputs, but we still did
prevent it from doing anything for integrated devices. Fix that, and change
output cycling so we don't allow a "NULL" EDID for integrated devices, this
makes those go through the MetaInputMapper (resulting in one output listed
twice), instead of mapping to the full stage.

The cursor tracker may give us a valid position, and a
valid cursor sprite, and yet the cursor can be hidden,
meaning we must hide the cursor on the stream as well.
Remove cursor from stream buffer if it's hidden.

Scanouts are taken away after painting. However, when we're
streaming, what we actually want is to capture whatever is
going to end up on screen - and that includes the scanout
if there's any.
Add a before-paint watch that only records new frames if a
scanout is set.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1421
It'll allow subclasses to get notified of the before-paint
signal without having to connect to it. This will allow
MetaStage to have proper watches being fired there without
the cost of the signal handling machinery.

When there's a direct scanout set in the stage view, we
have to use it instead of the view's regular onscreen
framebuffer.
Use the new CoglScanout API to implement blitting to the
stream framebuffer.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1421
This will be used when screencasting monitors so that if
there's scanout in place, it'll still be possible to blit
it to a PipeWire-owned framebuffer, and stream it.
Add a new 'blit_to_framebuffer' vfunc to CoglScanout, and
implement it in MetaDrmBufferGbm.

Just because X11/XI uses a particular terminology doesn't mean we
have to use the same terms in our own API. The replacement terms
are in line with gtk@1c856a208, which seems a better precedent
for consistency.
