Although mipmapping is still slower than not mipmapping, commit 16fa2100
simplified N synchronous draw calls per texture tower into just one. So
it's more efficient now, and four years have passed since the throttling
was introduced so people also have better hardware as well as mutter being
generally faster than it used to be. So I am happy to effectively revert
commit c9c32835.
This means antialiasing will remain consistent rather than popping in and
out of existence.

For this to pass, pass an explicit Wayland display name to avoid the
display conflict warning that may happen when there is an already
running Wayland display server.

Often, most of the output consists of a long list of exposed modes for
each monitor. If --short is passed, only pass modes that has properties.
In practice, this means "preferred" modes, "current" modes, and
similarly special cases, which significantly reduces noise.

Somewhat long overdue... We've been supporting more than a single
pointer for quite a long time now, let's make sure things don't break if
two pointer devices enter the same ClutterActor: Count the number of
pointers an actor has instead of using a simple boolean value.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2348>
In certain edge cases it's currently possible that an actor never
gets a valid allocation and paint volume.
One such case is adding an unmapped, hidden child to an unmapped
cloned parent and then showing the child. This happens currently
e.g. if a Wayland subsurface is added to a already mapped window
while the user is in the overview.
Ensure relayouts in two more such cases.

This one does proper error reporting. Via Javascript, barriers are
constructed directly via GObject construction, which currently can't
handle error reporting, but when calling from C we can. However, if we
initialize using GInitable, and use that in our constructor method, once
gjs gains support for construction using GInitable, including the error
reporting, we'll automatically get proper error reporting to Javascript.

In the past, barries were added to the window management X11 display
instance window table, and then special cased when iterating over the
list.
Since then, barriers, which are really part of the backend, has stopped
being added to the window hash table, instead being managed by the
backend. Lets clean up the left-over special casing that is no longer
needed.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2442>
Prior to this commit, barriers were created with a MetaDisplay pointer,
despite being entities related and owned by the backend. In the X11
case, it was also not hooked up to the backend X11 connection, but the
clutter one, meaning for example that the logic was active (but dormant)
also for the Xwayland connection.
Fix this by moving X11 barrier management and event processing fully to
the backend. Also replace passing a display pointer with passing a
backend pointer. Keep the display pointer around for a release, but mark
it as deprecated.

It papered over wrong `meta_rectangle_transform()` behaviour for
non-flipped output transforms. Also there is no obvious reason
why we would need inverted values here.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2459>
- Drop bogus `meta_monitor_transform_invert()`. It papered over
wrong `meta_rectangle_transform()` behaviour for non-flipped
output transforms.
- Update `scale_and_transform_cursor_sprite_cpu` to match the GL
pipeline matrix in `MetaShapedTexture`, fixing several of the
flipped cases. Note: the rotation applied is the one a client would
need to apply to the buffer for a given monitor transform.
- While on it, drop a redundant `return`.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2459>
With `META_MONITOR_TRANSFORM` values matching their `WL_OUTPUT_TRANSFORM`
counterparts, the definition from the Wayland spec applies: the
`META_MONITOR_TRANSFORM` value tells us how the output was rotated
and that the buffer was drawn by the client to compensate for that.
The matrix describes the transformation from surface- to buffer-
coordinates, so the operation we need here is the same one that
the client applied (not from buffer- to surface-coordinates, i.e.
the inverse).
While on it fix `FLIPPED_90` and `FLIPPED_270` to use the correct
axes: flip on the x-axis, rotation on the z-axis.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2459>
`meta_rectangle_transform()` is used in the stack to *compensate* for a
`MetaMonitorTransform` applied to a output, not to apply it again.
Change the function accordingly.
Context:
Experimenting with direct scanout on offscreen-rotated outputs revealed
that the 90/270 degree cases were actually interchanged.
Further digging revealed that we use `meta_rectangle_transform()` with
those values swapped in every single case, papering over the issue.
Either a unintuitive and unexplained `meta_monitor_transform_invert()`
was added, in which case "flipped" values would be wrong, or, in case
of Wayland buffer transforms, the values were swapped by interpreting
the Wayland enums accordingly, see commit 8d9bbe10.
Swapping the 90/270 degree values in `meta_rectangle_transform()`:
1. fixes hardware cursor positioning with flipped output transforms
2. fixes rendering issues with offscreen-rotated flipped output transforms
3. allows us to drop unexplained `meta_monitor_transform_invert()`s in
follow-up commits
4. allows us to make `META_MONITOR_TRANSFORM` and `WL_OUTPUT_TRANSFORM`
enums match again (reverting 8d9bbe10, as already done)
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2459>
The following implicit definition for `transform()` did not
correctly apply:
```
a * b = c
c * invert(b) = a
```
Crucially the following did not apply for `FLIPPED-90`
and `FLIPPED-270`:
```
a * invert(a) = identity
```
Fix this by applying the operations, first the flip, then the
rotation, in this order and add tests to ensure correct results
for the requirement above.
Also drop `relative_transform()` as it only had a single user and
can be replaced by `transform()`:
```
invert(a) * b = c
a * c = b
```
As this is not very intuitive, ensure in tests as well.

Checking for both bits at once means only one matching bit is
sufficient - very likely in case of `rotate-0'.
This fixes crashes on hardware that does not support 'reflect-'
bits when setting a flipped output transform.
While on it, also update the check for `reflect-y` instead of
`reflect-x` + `rotate-180`. They are logically equivalent,
however some hardware may support `reflect-y` but not both
other bits.
Fixes commit 4e3f3842a1
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2459>
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.
