The header linux/input.h used by GDK is specific to Linux. It is
possible to get a few Linux headers on FreeBSD by installing v4l_compat,
but it is usually better to use the one shipped with FreeBSD.
We prefer dev/evdev/input.h to linux/input.h here, so it will always use
dev/evdev/input.h on FreeBSD regardless of v4l_compat.

When pressing e.g. a window manager shortcut, which acquires keyboard grab,
Xorg would send FocusOut NotifyGrab then FocusIn NotifyUngrab. Currently
gdk would then deactivate the current surface, which makes accessibility
screen readers think that we have switched to a non-accessible application
and came back again, and thus reannounce the application frame etc. which we
don't want when e.g. just raising volume.
And actually, receiving FocusOut NotifyGrab does not mean losing the
X focus, it only means an application aqcuired a grab, i.e. it is
temporarily stealing keyboard events. On Wayland, this isn't even
notified actually.
This commit makes gdk only deactivate surfaces when there was an actual
focus switch to another window, as determined by has_focus_window (instead
of just has_focus), which happens either normally through FocusOut with
NotifyNormal, or during grabs through FocusOut with NotifyWhileGrabbed.
Fixes#85

The shortcuts inhibitors hash table is created when we create a
GdkWaylandWindow implementation for a GdkWindow, and it's destroyed once
we finalize the instance. The fake "root" window we create for the
Wayland display does not have a backing native window, so the shortcuts
inhibitors hash table is set to NULL; this causes a critical error
message when calling g_hash_table_destroy() on it. The finalization of
the root window happens when we close a display connection.
We should use g_clear_pointer(), instead, as it's NULL safe.
Without this change, the displayclose test fails, as all warnings are
considered fatal.
Epoxy 1.4 has new ad hoc API that we can use to check whether GLX is
available on the current system.
If we didn't use this API, we'd have to manually dlopen libGL (or its
equivalent on different OSes) and check if it had GLX symbols; since
Epoxy already does all of this internally, we can simply ask it instead.

When asked for a nonexistent (positive) monitor number,
gdk_x11_display_get_monitor would (at best) return an uninitialized pointer,
instead of returning NULL.

The stable xdg_shell port (5c8bb51a) introduced an error in
gdk_wayland_window_set_geometry_hints which would set the minimum size
to the maximum size, if provided.
This resulted in various wxWidgets apps (FileZilla, Audacity, Veracrypt)
crashing because they attempted to allocate a ginormous surface.
Fixes#157.
If a window is unmapped by the client while gdk is processing updates,
(for example Firefox un-mapping its window on Expose events), the
windowing backend resources might be lost (for example with Wayland)
which can cause a crash in end_paint().
Make sure we drop the cairo surfaces as well when hiding the surface,
that will avoid the crash in gdk_window_impl_wayland_end_paint() when
trying to attach the staging cairo surface to a released wl_surface,
these will be recreated when needed when the surface becomes visible
again and there is no need to keep such buffers around for a surface
which is not visible anyway.

This commit adds support the stable version of the xdg-shell protocol.
Support for the last version of the unstable series is left intact, but
will not receive new features.
The stable version is prioritized above the older version.

This was not needed before, but now it seems to be necessary for
some reason. The code is just an adjusted copy of the appropriate
piece of the OLE2 protocol code, sending GDK_SELECTION_REQUEST.
The rest is just fixing the fallout, allowing LOCAL protocol to pass
the functions it wasn't supposed to pass before.
Closes#82
When using type annotations, the ABI of type being annotated and a new
type introduced from annotation should match.
In case of enumerations, the most common ABI, and probably the only one
currently used in practice with gtk, corresponds to -fno-short-enums
compiler option. It uses int as the underlying type of enum, bumping it
up to unsigned int, long int or unsigned long int, in that order, when
necessary.
Thus, when annotating a field of integer type with an enum type, it is
never correct to annotate field smaller than int, because it changes the
ABI from perspective on introspection.
The gint8 phase field in GdkEventTouchpadSwipe and GdkEventTouchpadPinch
structures have been previously annotated in such a way, and this change
removes this annotation to restore ABI compatibility.
Size of structures before (which does not match C):
```
>>> Gdk.EventTouchpadPinch.__info__.get_size()
104
>>> Gdk.EventTouchpadSwipe.__info__.get_size()
88
```
Size of structures after (which does match C):
```
>>> Gdk.EventTouchpadPinch.__info__.get_size()
96
>>> Gdk.EventTouchpadSwipe.__info__.get_size()
80
```
Fixes issue #57.
The header got included without config.h being included first which resulted in the
wrong _GDK_EXTERN macro being used. As a result some symbols weren't exported
and starting a DnD action would crash in the linker.
This patch adds config.h includes in all places where clang complained about
_GDK_EXTERN redefinitions.
See #32 for more info.
The internal known_globals hashtable is used to carry accounting for
interfaces that depend on others (as ordering is not guaranteed), extend
its usage so it also keeps track of unimplemented interfaces (here at
least).
The API call will then use this to allow querying the globals offered by
the compositor, it will be useful to determine whether we can use
text-input protocols or should fallback to other IMs.

g_input_stream_read_bytes() roughly provides the same guarantees
than g_input_stream_read() wrt the number of bytes being possibly
read (i.e. it being a best effort, but no real guarantees).
Instead, rely on the 0-len read that we'd get at the end of the
transfer.
Fixes clipboard/DnD transfers possibly being cut short, resulting
on "Broken pipe" errors on the other side.

BTN_STYLUS3 is defined by the Linux 4.15 kernel and is sent when the
third button on a stylus is pressed. At the moment, only Wacom's "Pro
Pen 3D" has three stylus buttons. Pressing this button triggers a button
8 event to be sent under X11, so we use the same mapping here.

_gdk_win32_data_to_string() is only available when G_ENABLE_DEBUG is
defined, so as in gdkproperty-win32.c, use GDK_NOTE on the parts where
we assemble and output the debug messages.
In order to map a window with the correct initial parent-child
relationship when a modal dialog is set up to be a child of an imported
foreign window, the relationship must be set up before the window is
mapped.
In order to do this, if a window is not yet mapped, postpone the
relationship setup until when the window is eventually mapped.

After a pointer emulating GDK_TOUCH_END event triggering a fake leave
notify with GDK_CROSSING_TOUCH_END mode, pointer_under_window will be
unset, which will make the next motion/touch_update event to trigger
an enter notify event again.
Up till there, that's fine, however the motion event is just consumed
in favor of the just synthesized enter notify event. This is unexpected
to clients like spice-gtk that will only update coordinates from motion
events, sending both enter and motion is more consistent with X11 and
will make them happy.

It is unlikely that popup windows will contain anything that requires this
(popup menus being more interested in redirecting keyboard focus to
themselves). OTOH popup implementations that just grab the keyboard are
commonplace enough, it makes sense not to trigger inhibition for these.

No idea why it's here, the hash table can store any kind of data,
there's no reason why it wouldn't be able to store an old X string type.
Might be a holdout from the old days, when strings were handled in
a special way (stored directly in the clipboard?).

This prevents GTK from throwing a bunch of warnings when it tries
to get drag source window -> screen of that window -> ipc widget for that screen,
and then tries to attach a signal handler to that widget.
Specifically, this happens when we get a DnD move from another
application.

1) Ensure that any DELETE requests from the target are sent to GDK, even if
both the source and the target are in the same process and it
is therefore possible to use a shortcut and call the handler directly
in GTK layer
2) Ensure that target GDK doesn't do anything when GTK asks it to send
a DELETE request, just report back immediately (the code up the stack
does not check for successfullness when request is DELETE, so not giving
it any data is OK).
The source code already synthesizes a DELETE request, so that side is
also taken care of.

We need to know the target atom value to know when we need to
do something with side-effects (since side-effects are expressed via
special target values). Previously, the code side-stepped that by looking
at the data type (which was rather unique for the one side-effect
target that we supported, signalled by the TARGETS target),
but for the DELETE target that seems to be no longer an option, hence the new
field to carry this information past the convert_selection() routine.
This prevents GDK from throwing a warning when trying to convert
a DELETE target, which has no format or data objects set.
The side-effects for the DELETE target happen earlier, in GTK layer.
By the point it gets to change_property(), it's a no-op.

The wayland backend currently never emits GDK_SELECTION_CLEAR events.
GtkClipboard uses this signal in order to clear the clipboard owner when
the selection is set to something outside the application.
This commit ensures the wayland backend emits GDK_SELECTION_CLEAR before
setting the clipboard owner to NULL, as this means we lost the
selection.
