We have an abstract MetaWaylandDataSource and 2 subclasses for
clipboard/primary data sources. Since the abstraction provided
by the additional sublevel is arguable, push the wl_resource
field up, and leave us with just 2 objects to think about, all
of them containing a wl_resource.

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.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/845
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.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/793
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.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/842
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.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/842
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.

When starting a DnD operation, mutter would remove keyboard focus from
the client, only to restore it on the data offer destroy.
However, if the DnD fail, the keyboard focus is not restored, leaving
the user unable to type in the focused window, even after clicking in
the window.
That issue would show only on first attempt, as further DnD attempts
would destroy the previous data offer which would also restore the
keyboard focus.
Make sure we restore the keyboard focus on drag end as well.
https://gitlab.gnome.org/GNOME/mutter/issues/747
On drag start, `data_device_start_drag()` issues a keyboard grab, which
in turn will unset the current input focus.
There is not need to unset the input focus in `data_device_start_drag()`
as this is redone in `meta_wayland_keyboard_start_grab()`
https://gitlab.gnome.org/GNOME/mutter/issues/747
MetaWindowActor is the compositor-side representative of a
MetaWindow. Specifically it represents the geometry of the
window under Clutter scene graph. MetaWindowActors are backed
by MetaSurfaceActors, that represent the windowing system's
surfaces themselves. Naturally, these surfaces have textures
with the pixel content of the clients associated with them.
These textures are represented by MetaShapedTexture.
MetaShapedTextures are currently implemented as ClutterActor
subclasses that override the paint function to paint the
textures it holds.
Conceptually, however, Clutter has an abstraction layer for
contents of actors: ClutterContent. Which MetaShapedTexture
fits nicely, in fact.
Make MetaShapedTexture a ClutterContent implementation. This
forces a few changes in the stack:
* MetaShapedTexture now handles buffer scale.
* We now paint into ClutterPaintNode instead of the direct
framebuffer.
* Various pieces of Wayland code now use MetaSurfaceActor
instead of MetaShapedTexture.
* MetaSurfaceActorWayland doesn't override size negotiation
vfuncs anymore

When primary_offer_receive checks if the requested mime_type is supported,
it should check against the list of mime-types supported by the
primary-selection, instead of the list for the clipboard.
This fixes primary selection copy paste from X11 apps to Wayland apps
not working.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/702
On a successful DnD operation we may expect the wl_data_source and
wl_data_offer to live long enough to finish the data transfer, despite the
grab operation (and other supporting data) being gone.
When that happens, the compositor expects a wl_data_offer.finish request to
notify that it finished. However the client may still chose not to send that
and destroy the wl_data_offer instead, resulting in the MetaSelectionSource
owner for the DnD selection not being unset.
When that happens, the DnD MetaSelectionSource still exists but it's
detached from any grab operation, so will not be unset if eg. the drag
source client destroys the wl_data_source. This may result in crashes when
the next drag operation tries to replace the owner DnD MetaSelectionSource.
Check explicitly for this case, in order to ensure the DnD owner is unset
after such operations.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/591
A NULL argument is expected here in order to unset the selection,
meta_wayland_data_device_set_primary() accepts a NULL source, but
gtk_primary_selection_device.set_selection was not handling a
NULL wl_resource.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/335
Commit 70036429bd mixed drag_origin and drag_surface, leading to warnings
and invisible drag icon. Fix this up so we correctly set up the feedback
actor. This will correctly display the DnD icon alongside the pointer.
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
When repicking after a surface was destroyed, if the destroyed surface
was the drag focus, we'd try to focus-out from it after it was
destroyed, causing a NULL pointer dereference.

No XDnD events which notify DnD status change comes in Wayland. To emulate XDnD
behavior, MetaDnd checks whether there is a grab or not when the modal window
starts showing. When there is a grab, it processes the raw events from
compositor, and emits DnD signals for plugin.

Make the caller of focus setting and grab starting check whether there
is a keyboard to update the focus state or start grabbing. It makes it
more obvious what to expect, as the call would be a no-op in when no
keyboard is present.

We cannot check 'has-target' or 'has-seat' when verifying a
wl_data_offer.finish request is valid or not, since the source may have
effected 'has-target' or whether theh source has a seat or not when the
finish request was already on the wire.
Instead of checking against the source state, keep track whether the
required operations has been done on the offer in question (i.e.
whether an action has been sent, or a mime type been accepted).
This fixes incorrectly raised error when dragging from gtk+'s testdnd
via Xwayland onto gtk+'s testdnd using Wayland.

Allow passing parameters (only GObject parameters supported for now) so
that role assignment can affect the paremeters set during construction.
If a role was already assigned when assigning, the passed parameters
are set using g_object_set_valist().

A wl_data_device object may be created while it is being focused,
either because the client destroyed it or because the client was
destroyed. Handle this by early out in focus handler vfuncs the case
where it was destroyed, so that we don't corrupt memory and/or cause
segmentation fault.

This target is set whenever DnD moves towards an area between surfaces.
Although no offer is set and data is actually not read, drag sources
offering this mimetype will be able to behave just like they used to
do in X11.
https://bugzilla.gnome.org/show_bug.cgi?id=762104
We want some initial processing, even if the current focus didn't change.
This could be for example the case of starting DnD too close to the window
edge and out of it. At the point start_drag() is called, the current
pointer focus is already NULL, so set_focus() would simply bail out here.
https://bugzilla.gnome.org/show_bug.cgi?id=762104
Using the current position to set the origin x/y of the DnD icon
is wrong, it should still be used in order to move the icon besides
the current pointer position though.
Fixes possible drag-start-x/y property constraint warnings when
starting a drag too close to the window edge, and towards outside
of it.
This is necessary for the X11 side to catch up, and unset the primary
selection ownership on our window that represents the wayland side in
X11 selection.

In destroy_data_offer() there is code to ensure compatibility when
dragging from a v3 wl_data_device to a v2 one, it's however not checking
correctly that this is the DnD drag source. The other path should be
used otherwise.

Add an additional MetaWaylandDataSource implementation for primary selection
sources, and methods to set primary selection offers. Primary selection
sets altogether a different channel than the clipboard selection, those don't
cross in any way.
Also, the bridge for the X11 PRIMARY selection atom has been added, which
adds all the necessary handling to translate primary selection both ways
with wayland and X11 applications.

Since we are using the surface actor to draw the DND icon, the offset
is already accounted for by MetaSurfaceActorWayland, and passing the
surface position offset would effectively double the actual offset,
causing the icon to be misplaced.
This patch always sets the anchor offset to (0, 0) when the icon is a
Wayland surface, and lets the surface actor deal with the offsetting.
https://bugzilla.gnome.org/show_bug.cgi?id=759222
We now additionally send:
- wl_data_offer.source_actions
- wl_data_source.action
- wl_data_offer.action
- wl_data_source.dnd_drop_performed
- wl_data_source.dnd_finished
The protocol changes allow for compositors to implement different policies
when chosing the action, mutter uses this to reimplement the same behavior
that GTK+ traditionally had:
- Alt/Control/Shift modifiers change the chosen action to
ask/copy/move respectively
- Drags with middle button start out as "ask" by default
As mutter now also grabs the keyboard and unsets the window focus for these
purposes, the window focus is restored after the drag operation has
finished.
The Xdnd bridge code is also modified to cope with actions, so mixed
wayland-x11 scenarios are able to convey that information.
https://bugzilla.gnome.org/show_bug.cgi?id=760805
Each keyboard focus change ends up calling the MetaWaylandDataDevice
counterpart, we don't need though to notify the current selection
again. In order to fix this, keep track of the current client, and
only emit the relevant signals when the focus switches to another
client.
The situations where wl_data_device.selection were emitted during
focus changes between surfaces of the same client was inocuous most
of the times, although it's prone to inducing confusing behavior
on context menu clipboard actions, as the closing menu triggers a
focus change, which triggers a whole new wl_data_offer being created
and given on wl_data_device.selection, at a time where there's already
ongoing requests on the previous data offer.

Make a surface roles into objects with vfuncs for things where there
before was a big switch statement. The declaration and definition
boilerplate is hidden behind C macros.

Use a better name, use GNOME conventions for error handling, open code the
client error reporting and send the error to the correct resource.
wl_subcompositor doesn't have a role error yet, so continue use some
other error. The only effect of this is error received in the client will
be a bit confusing, it will still be disconnected.
