1b75d78c72 shaped-texture: Do not invalidate content on set_cogl_texture()
This was wrongly introduced in 75cffd0ec4. As the comment above explains, we
only want to queue redraws in response to surface/buffer damage.

This triggered a full redraw when using DMA buffers on Wayland as we currently
create a new texture on every buffer_attach(), breaking partial invalidation.

cbbffd1db7 cursor-tracker: Add API to keep the wayland pointer focus while hidden
Since commit a2a8f0cda we force the focus surface of the
meta-wayland-pointer to NULL while the pointer is invisible. This
introduced an issue with the a11y magnifier of the shell, which uses
`meta_cursor_tracker_set_pointer_visible` to hide the real cursor and
show its own magnified cursor at the correct position: Because the
meta-wayland-pointer is still used to communicate with Wayland clients,
the UI of the windows will not respond to mouse movement anymore as
soon as the real cursor is hidden.

Fix this issue for now by adding an additional method to the
cursor-tracker which allows disabling the behavior commit a2a8f0cda
introduced.

06202c342b device-manager-x11: Ignore events if no source device is set
There might be some inconsistent event for which we don't have a known
source device.

In the current state we don't handle them and we could crash when getting
the current device tool.

So, add an utility function that retrieves the source device for an event
that warns if no device is found, and use this for Motion, Key and Button
events.

In case we don't have a valid source in such case, just return early instead
of trying to generate invalid clutter events.

7e741fe2d2 wayland: Move "ownership" of the DnD selection source to the data device
On wl_data_source destruction we used to indirectly unset the DnD selection
owner via the wl_resource destructor triggering the destruction of the
MetaWaylandDataSource, which would be caught through the weak ref set by
the MetaWaylandDragGrab.

This works as long as the grab is held, however we have a window between
the button being released and the drop site replying with
wl_data_offer.finish that the MetaWaylandDataSource is alive, but its
destruction wouldn't result in the call chain above to unsetting the DnD
source.

In other selection sources, we let the MetaWaylandDataDevice hold the
"ownership" of the MetaWaylandDataSource, and its weak ref functions unset
the respective MetaSelection owners. Do the same here, so the
MetaWaylandDataSource destruction is listened for all its lifetime.

edb618b2a4 wayland: Do not cancel data source on offer destruction
This is wrong for both clipboard and DnD, as the selection source
will still be able to focus another surface, and churn another
wl_offer.

We should just detach the data offer from the data source in this
case, and let the source live on. However, we should still check
that there is a source and an offer to finish DnD, do that when
handling the drop operation instead.

7e5366f233 plugins/default: Handle skipped animations
We currently assume that the actor_animate() helper function returns
a timeline. However Clutter may skip implicit animations and simple
set properties directly, for example when the actor is hidden.

The returned timeline will be NULL in that case, and we abort when
using it as instance parameter to g_signal_connect().

Fix this by only setting up a completed handler when we are actually
animating, and complete the effect directly otherwise.

7c1f3498fe window-props: Don't set override redirect windows as top-level parent
Java applications might use override-redirect windows as parent windows for
top-level windows, although this is not following the standard [1].

In such case, the first non-override-redirect child window that is created
was marked as being on_all_workspaces since the call to
should_be_on_all_workspaces() returns TRUE for its parent, and this even
though the on_all_workspaces_requested bit is unset.
When a further child of this window was added, it was set as not having a
workspace and not being on_all_workspaces, since the call to
should_be_on_all_workspaces() for its parent would return FALSE (unless if
it is in a different monitor, and the multiple-monitors workspaces are
disabled).

Since per commit 09bab98b we don't recompute the workspace if the
on_all_workspaces bit is unset, we could end up in a case where a window can
be nor in all the workspaces or in a specific workspace.

So let's just ignore the transient_for bit for a window if that points to an
override-redirect, using the x11 root window instead.

Add a stacking test to verify this scenario (was failing before of this
commit).

6fa860481c wayland/actor-surface: Always store away frame callbacks on commit
We're expected by MetaWaylandSurface to always pick the frame callbacks
out from the pending state when committing (applying) so that no frame
callbacks are unaccounted for. We failed to do this if our actor for
some reason (e.g. associated window was unmanaged) was destroyed. To
handle this situation better, store away the frame callbacks until we
some later point in time need to pass them on forward.

1f56514e40 x11-display: Don't unset the X11 focused window after setting one
When using DesktopIcons extension and clicking in an icon, gnome-shell
starts an infinite loop caused by the first focus change that may trigger
on X11 a focus in/out event that leads to stage activation/deactivation
which never ends.

This happens because as part of meta_x11_display_set_input_focus_xwindow()
to focus the X11 stage window, we unset the display focus, but this also
causes to request the X11 display to unset the focus since we convolute by
calling meta_x11_display_set_input_focus() with no window, that leads to
focusing the no_focus_window and then a focus-in / focus-out dance that the
shell amplifies in order to give back the focus to the stage.

In order to fix this, mimic what meta_display_set_input_focus() does, but
without updating the X11 display, and so without implicitly calling
meta_x11_display_set_input_focus(), stopping the said convolution and
properly focusing the requested xwindow.
Also ensure that we're not doing this when using an older timestamp, since
this check isn't performed anymore.

f4574ea36f x11: Limit touch replay pointer events to when replaying
When a touch sequence was rejected, the emulated pointer events would be
replayed with old timestamps. This caused issues with grabs as they
would be ignored due to being too old. This was mitigated by making sure
device event timestamps never travelled back in time by tampering with
any event that had a timestamp seemingly in the past.

This failed when the most recent timestamp that had been received were
much older than the timestamp of the new event. This could for example
happen when a session was left not interacted with for 40+ days or so;
when interacted with again, as any new timestamp would according to
XSERVER_TIME_IS_BEFORE() still be in the past compared to the "most
recent" one. The effect is that we'd always use the `latest_evtime` for
all new device events without ever updating it.

The end result of this was that passive grabs would become active when
interacted with, but would then newer be released, as the timestamps to
XIAllowEvents() would out of date, resulting in the desktop effectively
freezing, as the Shell would have an active pointer grab.

To avoid the situation where we get stuck with an old `latest_evtime`
timestamp, limit the tampering with device event timestamp to 1) only
pointer events, and 2) only during the replay sequence. The second part
is implemented by sending an asynchronous message via the X server after
rejecting a touch sequence, only potentially tampering with the device
event timestamps until the reply. This should avoid the stuck timestamp
as in those situations, we'll always have a relatively up to date
`latest_evtime` meaning XSERVER_TIME_IS_BEFORE() will not get confused.

ef2f5f07f0 x11: Update X11 focus before updating MetaDisplay focus
In a similar vein to commit 8fd55fef85. This notably failed when setting
the focus on the stage (eg. to redirect key events to Clutter actors).
Deeper in MetaDisplay focus updating machinery, it would check
meta_stage_is_focused() which would still return FALSE at the time it's
called.

This would not typically have side effects, but our "App does not respond"
dialogs see the focus change under their feet, so they try to bring
themselves to focus again. This results in a feedback loop.

Changing the order results in later checks on the X11 POV of the focus
being correct, so focus is not mistakenly stolen from the close dialog,
and it actually succeeds in keeping the key focus.

a22731e2b2 clutter/actor: Save key-focus state and unset it before destruction
When clutter actors with key focus are destroyed we emit ::key-focus-out on
them just after their destruction. This is against our assumption that no
signal should be emitted after "::destroy" (see GNOME/mutter!769 [1]), and
in fact could cause the shell to do actions that we won't ever stop on
destroy callback.

To avoid this to happen, use a private function to set its key-state (so we
can avoid looking for the stage) and emit ::key-focus-in/out events and use
this value in both clutter_actor_has_key_focus(),
clutter_actor_grab_key_focus() and on unmap and destruction to unset the
stage key focus before we emit the ::destroy signal.

As result of this, we can now avoid to unset the key focus on actor
destruction in the stage.

5c1be2233d x11: Map mimetypes back to selection atoms
This may be seen as the missing half of
https://gitlab.gnome.org/GNOME/mutter/merge_requests/842. Now that we
translate some atoms to better known mimetypes, we should also translate
those mimetypes to the underlying atoms if we might have added them.

Fixes c&p from certain X11 clients.

e1751ad9ee wayland: Figure out better the right selection source for a wl_data_offer
We were just looking at DnD actions which might still be unset at that
point. Instead of doing these heuristics, store the selection type on
the data offer.

84cc89e19a wayland: Set dummy selection source on .set_selection(null)
Requesting a selection with a NULL data source means "unset the clipboard",
but internally we use an unset clipboard as the indication that the
clipboard manager should take over.

Moreover, this unset request may go unheard if the current owner is someone
else than the MetaWaylandDataDevice.

Instead, set a dummy data source with no mimetypes nor data, this both
prevents the clipboard manager from taking over and ensures the selection
is replaced with it.

The MetaSelectionSourceMemory was also added some checks to allow for this
dummy mode.

ea4665bf51 wayland: Simplify MetaSelectionSourceWayland
Instead of taking resource and send/cancel funcs, take a
MetaWaylandDataSource, which exposes all the vfuncs to do the same on the
internal resource.

This has the added side effect that only MetaWaylandDataSource has a
pointer to the wl_resource, which may be unset untimely.

227d272049 wayland: Check resource before emitting cancelled event
If a data source is destroyed we first unset the resource, and then try to
unref the related selection source. At this point the only event that might
be emitted by the internal selection machinery is .cancelled, so make sure
we avoid it on destroyed sources.

e53db92a7b wayland: Emit wl/primary offer after changing selection
We are still poking the mimetypes from the previous selection when creating
the new offer. This may come out wrong between changes of the copied
mimetypes.
