Assigning the corresponding stack layer of DOCK windows is currently X11
specific, because there is no way for wayland clients to set the DOCK
window type. This is about to change, so move the code to the generic
layer handling.

adaita-icon-theme cleaned up its cursor set, and now only provides
names defined by GTK/CSS. Update the cursor-hotplug test to not
use legacy cursor that will fail with a recent cursor theme.

meta_window_update_monitor() can emit "::highest-scale-monitor-changed",
and we connected to that signal right before. Let's avoid calling
meta_wayland_surface_notify_highest_scale_monitor() twice and move the
g_signal_connect() for that signal and the initial call to
meta_wayland_surface_notify_highest_scale_monitor() to happen after
meta_window_update_monitor().

Turns out there is a better solution: Almost always, MetaWindow already has
an idea on which monitor it will be, even if it isn't positioned yet. Since
the last commit we're now using that monitor for setting the
highest-output-scale of the window, so this fallback is no longer necessary.
While we could keep this fallback around and also return a valid scale in
case the surface is not even mapped yet, this means we report fractional
scale twice for new surfaces: Once from
wp_fractional_scale_manager::get_fractional_scale() (here we'll enter the
fallback), and a second time (this time with correct scale) right after
creating the MetaWindow.
Note that wp_fractional_scale_v1 doesn't specify that a preferred_scale
event must be sent immediately after
wp_fractional_scale_manager::get_fractional_scale(), so we can safely remove
the fallback.
This reverts commit 8cfbdb4313.

MetaWindow always tries to have a main monitor: If the frame rect is empty
and the window has not been positioned, in meta_window_constructed() we fall
back to asking the backend for the current monitor, and in
meta_window_wayland_update_main_monitor() we fall back to
meta_window_find_monitor_from_id(), which then falls back to the primary
monitor.
In general this means that window->monitor is always set as long as there is
a monitor around.
For getting the highest-scale-monitor the window is on, we currently rely
completely on the frame rect. If the frame rect is empty, we set the
highest-scale-monitor to NULL. Since we usually know though which monitor
the window is, or will be on, and window->monitor is even set to that, we
can just fall back to window->monitor for the highest-scale-monitor.
This makes sure ::highest-scale-monitor-changed is emitted right after the
window is created, and it's set to the correct monitor that the window will
be on. This in turn means that we can send a correct wp_fractional_scale
fraction_scale event to clients right away.

The existing comment tells us this is necessary:
> there may be drawing between the last damage event and the
> XDamageSubtract() that needs to be flushed as well.
But the commit message for 551101c65c also tells us that
synchronization is necessary before-update. Assuming both are correct
then it needs to be done in both places.
I did try optimizing out the second sync to only do it if damage
arrived during the update, but that doesn't seem to be the issue.
The damage event is arriving before the update starts and it's some
secondary changes within the damage region running late that need
flushing. So this means the client is reporting damage more frequently
than the frame rate and we're ignoring the secondary damage reports
for efficiency (XDamageReportBoundingBox), which is still a good thing.

Do not include it at header side as it is not part of the installed headers.
Only keep it in cogl-gl-headers.h as it is a private header.
Add it to all the source files that depend on it.

This change adds modifier-aware screencasting support to Mutter.
Implicit modifier support is kept for backward compatibility and the
code fallbacks to implicit modifiers in case any new functionality added
for explicit modifier support fails.
The advertised modifiers are retrieved by a call to
eglQueryDmaBufModifiersEXT() function. The "external only" modifiers are
excluded as Mutter uses the buffers created with the explicit modifiers
as renderbuffers. Support for implicit modifiers is checked with a test
allocation since there are drivers that do not support them.
This change also removes various implicit modifier support checks that
disable DMA-BUF screen casting support globally as they are no longer
needed. DMA-BUF support for screencasting is determined by the available
formats and modifiers case-by-case now.
It also effectively enables DMA-BUF screencasting on NVIDIA hardware as
well since GBM buffer objects with linear modifiers are no longer used
by default to create a renderbuffer object for screencasting.

meta_render_device_gbm_allocate_dma_buf() function is updated to take a
list of modifiers. If no modifiers are specified, the modifier is
selected by the allocator, and implicit modifiers are used to import the
created DMA-BUF.
