As testing of direct scanout revealed, `META_MONITOR_TRANSFORM`
does actually match `WL_OUTPUT_TRANSFORM` enums. The fact that
things rendered correctly with 90/270 degree values swapped
was because other parts of the stack got the interpretation
wrong, most notably `meta_rectangle_transform()`.
Thus lets revert this change and fix the stack accordingly.
This reverts commit 8d9bbe109b.

The notification list in the GNOME Shell calendar popup triggers some
interesting interactions when closing a notification:
- Close button is clicked
- The notification animates to be hidden
- The next notification ends up hovered as a result of the animation
- The notification being hovered sets its close button as non-transparent
and reactive
- The pointer is now again over a close button
At this point the reactiveness change should trigger a repick, so that
the new notification's close button is picked, and future button presses
are directed to it, but we do not handle this situation.
To fix this, handle actors becoming reactive so that if the closest
reactive parent has a pointer, it will be repicked again just in case
the pointer is over the newly reactive actor.

The function that currently invalidates pointers over an specific actor
also asserts for the situations where this invalidation makes sense to
happen (i.e. the actor became unmapped, or non-reactive).
We want to have a function that is more forgiving, and that doesn't
enforce any guarantees about the pointer focus actually changing.

We started to report resource changes using prediction when an update
had been successfully committed. While at it, gamma changes were
reported too, but this was problematic, as gsd-color will listen for the
MonitorsChanged D-Bus signal and naively set the gamma again, even if it
didn't change. There aren't currently any actual use cases for being
told when gamma changes from a prediction, so just ignore it and just
report privacy screen changes.
This avoids a feedback loop between mutter and gsd-color.

When we change the privacy screen, we added a result listener to the KMS
update object to notify the upper layer about the privacy screen state
change. This was slightly awkward as one might have changed the state
multiple times for a single update, thus it was necessary to remove any
old result listeners to an update before adding a new one.
Doing this will not be possible when updates are fully async and managed
by the KMS impl device.
To handle this, instead make the post-commit prediction notify about
changes that happens in response to a successfully committed update. We
already predicted the new privacy screen state, so the necessary change
was to plumb the actual change into a callback which emits the signal if
there actually was a privacy screen change.
This will then be communicated via the same signal listener that already
listens to the 'resources-changed' signal.

The name had a bit conceptual conflicts with MetaKmsUpdate, as it shared
its namespace but had no relation to it. Fix this by renaming it
MetaKmsResourceChanges (and the corresponding META_KMS_UPDATE_CHANGE_*
to META_KMS_RESOURCE_CHANGE_*). The term "resource" is used since that's
already used in the signal, and the fact that the changes partly comes
from changes in the DRM resource as retrieved by drmModeGetResources.

With this header we can set a flag to signal that the whole buffer is
corrupt and should be ignored. With this we can cater to all cases:
* Window buffer fine, but cursor broken:
Use the spa_meta_cursor properties like id or offset accordingly
* Window buffer broken, but cursor fine:
Use the chunk flags
* Both are broken / the dequeued buffer is not usable
Use the spa_meta_header flag
Additionally clients can now check if a buffer contains spa_meta_header
data and can thus only check for the new or the old behaviour.

`clutter_actor_iter_destroy` will try to match up the iterator's `age`
with that of the parent ("root") actor:
```
g_return_if_fail (ri->age == ri->root->priv->age);
```
In a simple actor graph that's completely reasonable but somewhere in the
more complex graph of gnome-shell the parent's `age` was skipping ahead
faster than that of the iterator. This could happen in theory if the
destroy indirectly leads to more children being destroyed than the
iterator has visited.
So there's no evidence of actual corruption, only the age check might
fail in a `clutter_actor_iter_destroy` loop because the age check itself
can't handle all possible valid scenarios.
Since our only mandate is to destroy all children, we can do that reliably
without an iterator and thus without assuming anything about the parent's
`age` counter.

PipeWire supports flags to signal a corrupted buffer. We should use the
flag SPA_CHUNK_FLAG_CORRUPTED for `chunk->flags` instead of setting
`chunk->size = 0` since the size isn't well defined for arbitrary dmabufs
and should be set to 0.
Sadly clients like obs are using a chunk size of 0 to decide if a buffer
should be imported. Thus we should offer both until clients are using
the flag.

When building the list of formats to be sent as part of the scanout
tranche, avoid requiring modifier support by the DRM driver for
formats relying on implicit modifiers (DRM_FORMAT_MOD_INVALID).
Specifically, the previous check required the DRM driver to have
advertised some modifier support for the given format in its
IN_FORMATS KMS plane property, regardless of modifier it was. If it
hadn't, the format was left out of the list of formats to be sent
in the scanout tranche.
When no formats remained to be sent in the scanout tranche, the
tranche simply wasn't sent.
This resulted in the scanout tranche never being sent for GPUs where
modifiers aren't supported. In those cases, no formats are advertised
using the IN_FORMATS property, and thus the list of formats to be sent
in the scanout tranche remained empty.
Since Mesa doesn't use scanout-compatible buffers for native Wayland
clients unless specifically requested to do so using the "scanout"
tranche flag, it effectively means that direct scanout of native
Wayland clients wasn't supported for GPUs without modifiers support.
Sending a tranche with formats paired with the implicit modifier
(DRM_FORMAT_MOD_INVALID) is both allowed by the protocol and is
already done by default for GPUs with modifiers support, unless the
experimental support for explicit modifiers is enabled in Mutter.
So instead of requiring modifiers to be supported for each format
being evaluated for the scanout tranche, when processing formats
which rely on implicit modifiers, only check if the format in
question is supported by the DRM driver for scanout on the primary
plane.

While the check for `clutter_actor_has_mapped_clones` clearly indicates
an intention to take clones into account, the following code
does not do so, likely because it predates the introduction of
`clutter_actor_is_effectively_on_stage_view()`.
Switch to that newer API in order to take clones into account. This
avoids unnecessary `wl_surface_send_enter()` and `wl_surface_send_leave()`
events when entering the overview, reducing client work.
This also avoids unnecessarily allocating a `cairo_region_t`.

Unparenting the surface actor when the subsurface object is destroyed
has several issues:
- subsurface actors can be unparented while a close animation is
still ongoing, breaking the animation for e.g. Firefox.
- adding and removing the actor to/from the parent is not handled in
one place, making the code harder to follow.
- if the destroyed subsurface had children of its own, they potentially
stick around until a surface-tree rebuild. This makes the Firefox
hamburger menu not close with the "compositor" backend.
Move the unparenting back to
`meta_window_actor_wayland_rebuild_surface_tree()` and instead just
notify the parent of a state change, if it still exist. This will ensure
a correct mapping between the subsurface node tree and the flat surface
actor list. In case of the closing animation the parent will already be
removed and the call is skipped.

Since b443bd42ac, we unmanage a wayland window when clearing its
transient parent. That's to make sure that xdg-foreign doesn't
leave the dialog around after the imported surface was destroyed.
While that behavior is sound, it is problematic to implement it
by unmanaging the window, as that happens entirely behind the
client's back.
Instead, send a close event for the window. Unless the client has
good reasons, it should honor the request. (And if it has good
reasons - like unsaved work - then effectively hiding the window
from both the user and client is probably not the best idea anyway).

Not all windows can be minimized: X11 clients can disable the
functionality, and so do we for windows that aren't shown in
the alt-tab popup or the shell overview, so there would be no
way of getting them back.
While we make sure that we respect that ourselves (keybinding,
window menu, etc.), we don't guard meta_window_minimize(), so
clients or extensions can still minimize a window that isn't
supposed to be minimized.
That can lead to all kinds of issues, from the hidden window
being lost (as far as users are concerned) to a crash when
the minimzed window has a transient parent.
Just add an explicit check to make sure the unexpected doesn't
happen after all, and print a warning if it does.

The cursor rendering code path used by the screen cast code relies on
the cursor tracker machinery to determine where to blit the cursor
texture, but at the moment the cursor position invalidation is behind
a check for whether the shell is using a Wayland backend. (This code
path used to be Wayland-specific before 00cbcb7ba1 but has been
backend-agnostic since).

cursor drawing to function correctly on X11 when screen casting in

The test case checks that the stage views of hidden actors are
not updated when the views of the visible outer parent change.
The check for the outer parent's updated stage views currently
relies on ClutterFixedLayout not excluding hidden children in
its size request: As the container doesn't contain any visible
children at that point, its size would change to 0x0 and end
up on no stage view (rather than the assumed two).
Avoid that oddity by giving the outer container a fixed size,
so that the visibility of its child doesn't affect the test
when we fix ClutterFixedLayout.
