Previously, the manufacturer property of the GdkMonitor was NULL,
and having at least PNP id at GdkMonitor.manufacturer makes it
possible to distinguish between different monitors programmatically.
xdg-output v3 marks xdg-output.done as deprecated and compositors are
not required to send that event anymore.
So if the xdg-output version is 3 or higher, simply set the initial
value `xdg_output_done` to TRUE so we don't wait/expect that event
from the compositor.

Windows/surface's aren't supposed to be explicitly moved by any external
part, so don't provide API for doing so. Usage throughout Gdk is
replaced by the corresponding backend variants.
The generic layer still does the heavy lifting, leaving the backends
more or less just act as thin wrappers, dealing a bit with global
coordinate transformations. The end goal is to remove explicit surface
moving from the generic gdk layer.
To separate how toplevels and popups are configured, a first step is to
introduce a resize-only vfunc for backends to implement. It's meant to
only configure toplevel windows, i.e. popups. Currently it's used for
both types, but introducing the resize-only API is a first step.
Configuration should happen in response to the xdg_surface.configure
event, not in the events that preceeds it. Do this by making all
configured state pending until the committing "configure" event. Also
split up toplevel vs popup configuration in a more clear way.
When unreffing the stream from a different thread, the close function
will schedule its cleanup asynchornously in the main thread.
We need to make sure the stream object stays alive for as long as
that hasn't happened, so ref() it.
Fixes#2003
Instead of the toplevel driving popups, have the popups listen to the
frame clock themselves. Otherwise, if the toplevel for some reason isn't
drawn by the compositor and stops drawing new frames, popups wouldn't
get painted either.
To make a frame clock tick as long as any of the associated surfaces
expect to receive ticks, make the surfaces inhibit freezing the clock,
instead of directly tell the frame clock to freeze itself.
This makes it so that as long as any surface using a certain frame clock
is not frozen (e.g. just received a frame event from the display
server), the frame clock will not be frozen.
With this, the frame clock is initiated as frozen, and won't be thawed
until any surface inhibits freeze. It will be frozen again, when every
surface has that previously inhibited freeze uninhibited freeze.
The xdg_output v2 interface has a `name` property that reflects the
output name coming from the compositor.
This is the closest thing we can get to a connector name.
The migration from GdkScreen's monitor API to GdkMonitor left out a way
to get the connector's name of a monitor.
While there's no real guarantee coming from the underlying graphics
system that the connector's name is stable, some system components may
use it to uniquely identify a monitor until the next plug in/out event.
This gives us marks to track the duration of processing certain types of
GdkEvent. It also provides some basic struct information in cases where
having that information would likely be useful for debugging.
The Wayland backend has a hack to work around
a race with popover mapping: If the surface size
changes before the initial configure, we hide and
show the surface. Unfortunately, the code was doing
this in a way that is externally observable (by
listening for surface state changes), and popovers
were observing it and hiding themselves in response.
Avoid this by not going through the GDK frontend
code for this.
1) In the SetWindowPos() function (and the WINDOWPOS struct) the
"hWndInsertAfter" argument/field means the window that will be
directly above after the change, not the window that will be
directly below. MSDN says "precedes" for SetWindowPos(), but
WINDOWPOS documentation is more precise: this is the window
behind which the affected window will be placed. Apparently,
Z-axis goes back-to-front.
Therefore, logging should be reworded correctly.
2) When we switch away from the application and then switch back
to a transient window, we need to bring up its transient-owner
(and its transient-owner's owner and so forth) as well,
otherwise our transient (modal) window might be transient for
something that might not be visible.
3) When we bring up a window, we should bring all of its children
(popup windows) on top of it.
Because Windows doesn't provide a function to bring one window
on top of the other, we have to work around this by calling
SetWindowPos() twice, swapping the windows between the calls.
Similar to previous removals of g_cclosure_marshal_VOID__VOID we can remove
other marshallers for which are a simple G_TYPE_NONE with single parameter.
In those cases, GLib will setup both a c_marshaller and va_marshaller for
us. Before this commit, we would not get a va_marshaller because the
c_marshaller is set.

This uses the new sysprof-3 ABI to implement the capture writer. It also
uses the statically linked libsysprof-capture-3.a that is provided with
Sysprof for the capture writing to ensure that we do not leak any symbols
nor depend on any additional libraries.
The GTK_TRACE_FD can be used to pass a FD for tracing into Gtk. Sysprof
uses this when the Gtk instrument is selected for recording.
If we set c_marshaller manually, then g_signal_newv() will not setup a
va_marshaller for us. However, if we provide c_marshaller as NULL, it will
setup both the c_marshaller (to g_cclosure_marshal_VOID__VOID) and
va_marshaller (to g_cclosure_marshal_VOID__VOIDv) for us.
Root coordinates are going away, so this
api does not make sense anymore. Use
gdk_surface_get_device_position instead.
We still keep this as internal api for
root-coordinate using backends.
The X backend was storing global coordinates
in surface->x/y, and keeping the parent-relative
positions in its own fields. Switch this around
to store the relative position in x/y, as is
expected by the frontend.
This function returns the position relative to
the surface parent, so will always return 0 for
non-popups. The out arguments don't need to
allow-none either - nobody passes NULL for these.
We maintain offsets for popups, so we can translate
coordinates between surfaces that are attached directly
or indirectly to the same toplevel. Add an api for that.
CSS does not do exponents, so printing numbers close to 0 as 1.234e-15
does not work.
Also up the accuracy to 17 digits because that's what everyone else
uses.
