c17d85e16b wayland: Let MetaWaylandTabletManager process tablet events
meta_wayland_tablet_manager_update()/handle_event() are called before
the MetaWaylandSeat counterparts. If the event comes from a device
managed by MetaWaylandTabletManager, the event will be exclusively handled
by it.

ec53b5562d wayland: Implement wl_tablet_tool.set_cursor
Each tool has its own MetaCursorRenderer instance, which is created/destroyed
upon proximity, and possibly updated through focus and set_cursor calls in
between.

d990f873c1 wayland: Add MetaWaylandTabletManager
This struct keeps the server side information for the wl_tablet_manager
global resource. It keeps the clients requesting this interface, and
does keep track of the plugged tablet devices, so
wl_tablet_manager.device_added is emitted on the expected clients.

5849275b76 wayland: Refactor MetaWaylandSurfaceRoleCursor
Move into a standalone meta-wayland-surface-role-cursor.[ch], and
make generic enough to work for pointe and additional (eg. tablet)
cursors.

Most notably, the sprite is now kept completely internal to the
cursor role, and updates are routed through the given
MetaCursorRenderer (which may be the default one for the pointer,
or something else).

The way cursor updates after cursor surface destruction has also
been reworked, the pointer will just keep track of the last cursor
surface, so older surfaces being destroyed don't trigger pointer
rechecks/updates.

1acfcbda6c wayland: Add MetaWaylandSurface::destroy signal
There's places where it would be convenient to add listeners to this,
so add the signal. The signal is only emitted once during destruction,
it is convenient for the places where we want notifications at a time
the object is still alive, as opposed to weak refs which notify after
the fact.

5f5d8f4091 Drop local g_autoptr definitions for generated code
Sadly, GLib's autoptr cleanup macros cannot be detected by the C
pre-processor, because they generate a function. This means that we are
forced to bump up the dependency on GLib 2.49, in order to build against
a newer version of gdbus-codegen.

aeda556af1 Don't re-define auto cleanup symbols
Starting from GLib 2.49, the gdbus-codegen tool automatically generates
the auto cleanup symbols for the GDBus proxy and skeleton interfaces.

Since we don't depend on a specific version of GLib we need to
conditionally generate the auto cleanup symbols in case an older version
of gdbus-codegen is used when building Mutter.

This commit unbreaks the build under GNOME Continuous, which has been
failing with:

bca041b68e MetaWindow: Make buffer_rect and rect share coordinate space
Before this commit, on Wayland, the buffer rect would have the size of
the attached Wayland buffer, no matter the scale. The scale would then
be applied ad-hoc by callers when a sane rectangle was needed. This
commit changes buffer_rect to rather represent the surface rect (i.e.
what is drawn on the stage, including client side shadow). The users of
buffer_rect will no longer need to scale the buffer_rect themself to
get a usable rectangle.

Move xdg_shell related functionality to a new meta-wayland-xdg-shell.c
and wl_shell related functionality to a new meta-wayland-wl-shell.c,
and adapt role object tree.

Common functionality related to the surface being drawn as a
MetaSurfaceActor was moved to a MetaWaylandSurfaceRoleActorSurface role.

The subsurface role GObject is made to inherit the actor surface GObject.

Shell surface hooks (configure, ping, close, popup done) were added to
a MetaWaylandSurfaceRoleShellSurface GObject which inherits the
surface actor role GObject.

The shell surface roles (xdg_surface, xdg_popup, wl_shell_surface) are
made to inherit the shell surface GObject and implement the relevant
API.

a6cc35e595 wayland: remove pressed button checks from meta_wayland_pointer_can_grab_surface()
Leave these checks up to the callers, the only uses of this function
(indirect, through meta_wayland_seat_get_grab_info) are
[wl_shell|xdg]_surface.move/resize/show_window_menu.

In move/resize it makes sense to check for a button being pressed, because
we must expect a button release event. However for xdg_surface.show_window_menu
we 1) don't strictly need further events and 2) we must account for press+release
event pairs being processed at once in the compositor before the client sees
the former.

That is eg. the case of touchpad 2nd/3rd button tap emulation, multifinger
taps will emit the event pair at once, so when the client manages to request
xdg_surface.show_window_menu, it'll be too late in the compositor side, so the
request is ignored.

f44238a72f MetaWaylandSurface: Keep an extra buffer use count for role-less surfaces
Whether a surface needs to keep the committed wl_buffer un-released
depends on what role the surface gets assigned to. For example a cursor
role may need an unreleased shm buffer in order to create a hw cursor from
it.

In order to support this, keep a separate reference and use count to
the buffer on behalf of the in the future assigned role, and release
those references after the surface was assigned a role. A role that
needs its own references and use counts, must in its assign function
make sure to add those.

have received as many release events as it has attached and committed

51e4491a9f wayland: Force an initial focus in meta_wayland_drag_grab_set_focus()
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.

8b801aac77 Handle meta_screen_get_monitor_for_point() returning NULL
On the X11 backend we don't track the pointer position in
priv->current_x/y which remain set to zero. That means we never set
the clutter stage cursor if point 0,0 isn't covered by any monitor
since we return early.

Commit 4bebc5e5fa introduced this to
avoid crashing on the prepare-at handlers when the cursor position
doesn't fall inside any monitor area but we can handle that higher up
in the stack. In that case, the sprite's scale doesn't matter since
the cursor won't be shown anyway so we can skip setting it.

f6ba3bdfc2 wayland: Add gtk_surface.present to gtk-shell
This commits adds a gtk_surface.present request and its implementation.
The timestamp is assumed to be from some input event that the client
responded to. The timestamps we deal with when managing windows will
usually come from two different clocks: CLOCK_MONOTONIC if they come
from libinput/evdev, or CLOCK_MONOTONIC_COARSE if they come from the
X server.

Luckily these are quite similar, the difference beeing that the X server
timestamps having lower resolution, so we can just pass the timestamps
no matter where they came from and it'll most likely work fine, except
for the race condition described in bug 756272 which might happen here
too until it is properly fixed.

to do any compatible changes without breaking things.

So, instead rename it to include a number in the interface names. This

0882bce989 startup-notification: Ensure provided timestamp is always a 64 bit integer
The libsn API provides its timestamps in the "Time" X11 type, which is
usually is a typedef for "unsigned long". The type of the "timestamp"
parameter of StartupNotificationSequence is a signed 64 bit integer.
When building on an architecture where a "unsigned long" is not 64 bit,
we'd then pass a 32 bit unsigned integer via a va_list where a signed 64
bit integer is expected causing va_arg to read past the passed 32 bit
unsigned integer.

Fix this by ensuring that we always pass the expected type via the
va_list. Also change the internal timestamp type from time_t (which
size is undefined) to gint64, to avoid any potential overflow issues.

We currently track whether or not a buffer can be released early
by looking at the copied_data boolean on the buffer.  This boolean
is, practically speaking, always set to TRUE for shm buffers and is
always false otherwise.

We can just as easily check if the buffer is a shm buffer to decide
whether or not to do an early release.  That's better from a
theoretical point of view since copied_data assumes a 1-to-1
relationship between surface and buffer, which may not actually hold.

This commit drops copied_data and changes the check to instead see
if the buffer is shm.

495c89401a Implement support for the wp_pointer_constraints protocol
The wp_pointer_constraints protocol is a protocol which enables clients
to manipulate the behavior of the pointer cursor associated with a seat.

Currently available constraints are locking the pointer to a static
position, and confining the pointer to a given region.

Currently locking is fully implemented, and confining is implemented for
rectangular confinement regions.

What else is lacking is less troublesome semantics for enabling the lock
or confinement; currently the only requirement implemented is that the
window that appears focused is the one that may aquire the lock.

This means that a pointer could be 'stolen' by creating a new window that
receives active focus, or when using focus-follows-mouse, a pointer
passes a window that has requested a lock. This semantics can be changed
and the protocol itself allows any semantics as seems fit.

f0f638d2bd Move out generic math parts out of the native barrier implementation
In order to reuse some vector math for pointer confinement, move out
those parts to its own file, introducing the types old types
"MetaVector2" and "MetaLine2" outside of meta-barrier-native.c, as well
as introducing MetaBorder which is a line, with a blocking direction.

5b0eabec51 wayland: Implement support for wp_relative_pointer
Add support for sending relative pointer motion deltas to clients who
request such events by creating wp_relative_pointer objects via
wp_relative_pointer_manager.

This currently implements the unstable version 1 from wayland-protocols.

50099c4c10 wayland: use glib function for fetching timestamp
The code currently implements a function, get_time, that
fetches a timestamp.  That duplicates code already in glib,
and the glib implementation is better, anyway, since it doesn't
skew backward when the system clock is changed.

This commit changes the code to use g_get_monotonic_time and
drop the get_time function.

Instancing a gbm device without initializing EGL with it means that it

gbm device which is already properly initialized.

f9db65f47f theme: Take invisible borders required by the theme into account
GTK+ paints some elements like box shadows (which Adwaita likes to (ab)use
for borders) outside the rectangle passed to gtk_render_*. This is not
an issue if our own invisible frame border is big enough, but in case
of non-resizable windows we end up clipping away part of the decoration.
Use the newly added gtk_render_background_get_clip() to make sure we
always use a mask that is large enough to contain all decorations.

7adbb58736 wayland: don't prematurely release EGL buffers
commit 0165cb6974 changed
mutter to release committed shm buffers as soon as they were
uploaded to the GPU.

It also inadvertently changed mutter to prematurely
release EGL buffers (which never get copied, but get used
directly).

This commit corrects that mistake.

0165cb6974 wayland: release buffer after processing commit
When a client is ready for the compositor to read a surface's
shared memory buffer, it tells the compositor via
wl_surface_commit.

From that point forward, the baton is given to the compositor:
it knows it can read the buffer without worring about the client
making changes out from under it.

After the compositor has uploaded the pixel contents to the video
card it is supposed to release the buffer back to the client so that
the client can reuse it for future use.

At the moment, mutter only releases the buffer when a new buffer
is attached.  This is problematic, since it means the client has
to have a second buffer prepared before the compositor gives the
first one back.  Preparing the second buffer potentially involves
copying megabytes of pixel data, so that's suboptimal, and there's
no reason mutter couldn't release the buffer earlier.

This commit changes mutter to release a surface's buffer as soon
as it's done processing the commit request.

bcdda506e1 MetaWaylandDataDevice: Don't set surface offset as anchor offset
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.

9b26694bbc wayland: Implement DnD actions as per wl_data_device v3 changes
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.

ec9abaf1ef wayland: Add MetaWaylandKeyboardGrab and keyboard grab API
This will be useful during DnD, where mutter is expected to consume
keyboard events for either allowing changes in the selected DnD action,
or misc a11y features like keyboard-driven DnD.

Currently, the vtable contains 2 functions, key() will be used on every
key event we get from Clutter, modifiers() will notify of changes in the
keyboard modifiers (mouse buttons will never be set in the modifier mask)

935d76ba04 wayland: Implement wl_pointer.axis_source/axis_stop/axis_frame emission
As per the spec:
- wl_pointer.axis_source determines the current source of
  scroll events.
- wl_pointer.axis_stop determines when there's no further
  scroll events on the given axis.
- wl_pointer.axis_discrete is emitted on "wheel"
  scroll sources, measured in ticks.
- wl_pointer.frame is meant to coalesce events that logically belong
  together, e.g. axis events in this case.

Some of the mutter code using these properties expects them to be

This was in some cases resulting in the WM_CLASS property containing

5e57af6286 idle-monitor-native: Don't leak user active watches
This fixes an issue analogous to bug 760330 for the X11 backend,
except on this backend we wouldn't crash accessing free'd memory.

Instead we're leaking watches since we steal them from the hash table
which means that when they're removed in
_meta_idle_monitor_watch_fire() they're no longer there and thus
they're never free'd.
