f692974e5a gdk: Remove remnants of client-side windows
Now that all surfaces are native, we don't need
to separately keep track of grab surfaces and
their native ancestor anymore.

713fceb1bd wayland: Use scale from core wl_output protocol
The “xdg-output” protocol provides clients with the outputs size and
position in compositor coordinates, and does not provide the output
scale which is already provided by the core “wl_output” protocol.

So when receiving the wl_output scale event, we should update the scale
regardless of “xdg-output” support, otherwise the scale will remain to
its default value of 1 and the surface will be scaled up by the
compositor to match the actual output scale, which causes blurry fonts
and widgets.

e74c655016 wayland: Make popups work more than once
The change to keep some server resources around
until destroy was causing us to not recreate
the right things when a surface is hidden and

f2d598b9a1 wayland: Keep some resources until destroy
The Wayland backend was dropping _all_ serverside
resources on hide, which is too early e.g. for
GtkGLArea which wants to use egl resources to
unload textures on unrealize.

33ffd54d5f Redo frame profiling

numbers. Instead, only add timings to the profile
once we marked them as complete. This also

1f58e0ed6b wayland: Add support for xdg-output
Previously, the GDK backend for Wayland would deduce the logical size
of the monitors from the wl_output size and scale.

With the addition of fractional scaling which advertises a larger scale
value and then scale down the client surface, the computed logical size
of the monitors in GDK would be wrong and confuse applications which
insist on using the monitor size and position (like Firefox).

The xdg-output protocol aims at describing outputs in a way which is more
in line with the concept of an output on desktop oriented systems by
presenting the outputs using their logical size and position appropriately
transformed.

Add support for the optional xdg-output protocol so that the size and
position of the monitors as reported by GDK is correct even when using
fractional scaling.

8385543e1c gdkdevice-wayland: Update pointer scale on tablet tool proximity events
When the user approaches a tablet tool to the screen we get a proximity-in event

to be applied to the cursor.
And the same should be done when the tool is detached or the monitors
configuration changes.

94745241c2 GdkGLContext: Fix damage computation with buffer_age
As per the spec:

> The back buffer can
> either be reported as invalid (has an age of 0) or it may be
> reported to contain the contents from n frames prior to the
> current frame.

So a  buffer age of 1 means that the buffer was used in the last frame.
We were handling buffer_age==1 the same as buffer_age==0, i.e. we
returned the full damage for the surface.

938448e0ef display: Add new virtual gdk_display_get_startup_notification_id() method.
Includes implementation for Wayland and X11, which are the only backends
implementing the Startup Notification Protocol, returns NULL otherwise.

ef3427575f display: Avoid unsetting the DESKTOP_STARTUP_ID variable too late
Similar to what has been done recently for DESKTOP_AUTOSTART_ID [1],
we need to get rid of this call to g_unsetenv() in the displays'
backends for X11 and Wayland, so that it's guarantee to happen any
thread is created, while still being accessible when needed.

Let's stash the value of this environment variable when loading the
GDK library, and provide a private method so that it can be retrieved
from the displays' backend when implementing gdk_display_make_default().

a5d000cb5c wayland: Fix restarting cursor animation
When an animated cursor was set and the previous cursor animation delay
happened to be the same, we wouldn't restart the animation timeout and
just return G_SOURCE_CONTINUE assuming the timer would continue. This
assumption is however only valid if the function was called from the
timeout, which is not the case.

Instead also arm the timer also if there is no previous timer active.

d3885e92a7 wayland: check native surface for crossing events
gdk_wayland_*_grab()/ungrab() would emit crossing events which translate
as focus_in/focus_out events for keyboard.

However, the ungrab() functions compare the native toplevel as this is
what gets the Wayland pointer enter/leave events with the grab surface,
so if the grab is issued on a child gdk surface, those won't match and
we would emit more focus_out events than focus_in.

This means that a widget such as spice-gtk which issues a keyboard grab
whenever the pointer enters the surface and releases the grab when it
leaves the surface would get uneven numbers of focus_in/focus_out
events.

Also, gdk_wayland_seat_ungrab() would not emit crossing events for
keyboard devices, whereas gdk_wayland_device_ungrab() does, which adds
even more potential discrepancies between focus_in/focus_out events.

To solve this problem, introduce two new helper functions which check
the relevant native surfaces to emit crossing events when needed that
get called evenly from both gdk_wayland_seat_grab()/ungrab() and gdk
_wayland_device_grab()/ungrab() APIs.
