We have various layers where we store the startup ID for a request,
since this API does not have a GdkToplevel that we can refer about
for the Wayland platform, this is the most obvious candidate to
start untangling these various layers.
Deprecate this call, it is already unused in the gtk/ side.
In the way towards deprecating gdk_display_notify_startup_complete(),
make gdk_toplevel_set_startup_id() on X11 perform this piece of messaging
itself. It should be harmless that the message is emitted twice, if
callers do still use that API.
This call has everything to perform activation as specified by the
xdg_activation protocol, notably a surface to activate as opposed to
gdk_display_notify_startup_complete().
Make activation happen here, so that the surface gets activated when
its gets a startup ID assigned.
The owner_events=TRUE grab makes GDK on X11 see events happening
outside every client window as received on the grab window.
Additionally check that the pointer is inside the grab window
(i.e. it received GDK_CROSSING_NORMAL crossing events for the
core pointer) in order to handle clicks happening outside client
windows.
These new paths are expected to be a no-op on Wayland, and to
also work for touchscreen input on X11, due to emulated pointer
events.
Try to get a native file:// URI instead of any other GVFS
scheme, for interoperability with apps only handling file:// URIs.
This is what GTK3 Nautilus and Thunar do, so apps should be tuned
for this behavior.

A Drag surface does not have a parent surface. Therefore, if we initialize
it with one, it's inheriting the frame clock from the parent, but the
drag surface is not linked to the parent. Once the drag surface is destroyed,
it's disposing the frame clock, which results in a "frozen" application.
This is an extra safeguard that avoids grabbing resources longer than
nessecary. It also ensures the resource is removed from the drag,
so it is not freed again.
Currently, the GdkSurfaceX11 implementation relies that the upper
layers hid the surface before destruction, and that no
GdkSurfaceClass.compute_resize happened between them. If these
circumstances happened, there would be a compute_size timeout left
dangling after the surface got destroyed, poking at incorrect data
later on. Something that looks like this was reported in the
recent mutter-x11-frames "SSD frames server":

It perhaps makes sense to warn in these situations, but either way
it sounds like gdk_surface_x11_finalize() could enforce the correct
behavior by ensuring there is no dangling timeouts/data. This commit
does that.
The argument to xdg_activation_token_v1_set_surface is documented to be the
surface requesting the activation, not the surface to be activated, which is
given later when calling xdg_activation_v1_activate.
(c.f. 36cee4bdbc)
Use the same logic as in gdk_wayland_app_launch_context_get_startup_notify_id,
i.e. if we have a surface with focus, set that, otherwise set NULL.
This fixes requesting urgent/focus on wlroots (compositors like Sway, etc.),
which was blocked as the surface requesting the activation didn't have focus.

By using wl_output_release(), GDK lets the compositor to clean up the
output global more nicely.
For example, currently, most compositors remove the global and then
destroy it later after N seconds expire. With this, the compositor could
experiment with destroying the output global once all its resources are
destroyed.
this is to prevent gdk from causing a segfault, when getting event axes
for events that don't have them (i.e. attempting to get pressure from a
mice input device).
GDK_TOUCH_END deserves the same treatment than GDK_BUTTON_RELEASE, since it's
subject to the same circumstances (popping up a menu on long press would be
immediately dismissed on release if we handled them there). Ideally, we would
want to match releases that we obtained a press for while grabbed, but as
the popup is also dismissed on GDK_BUTTON_PRESS/GDK_TOUCH_BEGIN, there's no
use for this tracking.
And GDK_TOUCH_CANCEL sounds weird as a reason to dismiss popups, just like
crossing events would.

clang complained that we may end up jumping
to the cleanup code without initializing data
in the jpeg code. Always initialize data to
NULL to prevent that eventuality.
GTK knows when a surface is modally blocked and automatically drops
button press and release events, so do not block input in advance
from WM_MOUSEACTIVATE.
This is largely adapted from commit 83027c68f1 ("11: Implement
inhibit_system_shortcuts API"), with similar rationale:
To implement the inhibit_system_shortcuts API on X11, we emulate the
same behavior using grabs on the keyboard.
To avoid keeping active grabs on the keyboard that would affect
other X11 applications even when the surface isn't focused, the X11
implementation takes care of releasing the grabs as soon as the
toplevel loses focus.
Note that Windows has low-level keyboard hooks that could help achieve
the expected behaviour. This is implemented by spice-gtk & gtk-vnc for
example, but correctness isn't obvious. I left a TODO comment.
This patch helps implementing remote desktop widgets with GTK4, since
currently on win32 backend Alt-Tab and such are always left to the
system unless there is keyboard grab (which can't be requested by the
client API anymore, afaict).

There's 2 things broken here:
- The mask was calculated on top of the GDK button (i.e. skipping
4-7 buttons), so GDK_BUTTON4_MASK and GDK_BUTTON5_MASK were not
assigned. This is now calculated on the (continuous) BTN_ evcodes
so it is guaranteed that the next 2 physical buttons (i.e.
back/forward) get these two places in the mask assigned.
- Furthermore, these buttons would be pushed to places in the
modifier mask that they didn't belong to. It is now checked hard
that only the first 5 buttons enable a modifier flag.
Overall, this ensures that no event masks with bonkers values are
forwarded, and that no stale implicit grabs are left after additional
buttons are pressed.

This makes GtkSettings values on X11 match what we get on
other backends.
Reporting size settings in logical pixels (i.e for scale
== 1) is useful for properly supporting mixed-DPI setups.
As X11 doesn't support mixed-DPI setups anyway, XSettings
doesn't bother providing logical values. Thus we scale
from physical to logical values ourselves.

When getting the serial for primary/clipboard selections we used a
function that largely relied on a GdkEvent being passed. We have
another available function that looks up the most recent serial
given the ongoing touch/tablet input as well.
This is the second best, compared to actually knowing the
input/device from the event that was received by the UI an triggered
the clipboard operation, and is already in use in other places
(e.g. window dragging). It is valid for these situations too.

Use newlines rather than spaces to separate file paths (or uri's)
when serializing text/plain files. There isn't a matching
deserializer, so we can do this in isolation. Newlines
seem to make more sense when pasting into a text editor etc.

As documented on MSDN:
> Unlike the WM_LBUTTONUP, WM_MBUTTONUP, and WM_RBUTTONUP messages, an
> application should return TRUE from this message if it processes it.
Empty/zero bounds are sent by the Wayland compositor if there are no
valid bounds to report, e.g. if there are no connected monitors. Report
this to GTK, which uses this to clamp calculated sizes, as INT_MAX, so
that clamping isn't done until there are actual valid bounds to clamp
to.
This fixes clients sometimes shrinking to their minimum size during
hotplugs or after having suspended the session.
We shouldn't assume there is always a monitor to derive bounds from.
If there is no monitor, pass empty bounds, as this matches what
xdg_toplevel.configure_bounds do in this case.
GTK4 gdk/broadway: correct gdk_broadway_device_query_state() to return pointer coordinates relative to the upper left corner of surface

As far as I'm aware, these only exist with `gdk_wayland_surface_` names
for historical reasons, before these types were split.
This way, those functions will be able to access members of the
`GdkWaylandToplevel` struct. And it just saves a few lines of code.
There is nothing particularly specific to drawables
in there (and we don't have that concept anymore),
so just name the source file to match the header.
Easier for everybody.
Move the autocleanup declarations into their
respective headers.
While we are at it, correct the autocleanup
declaration for GdkEvent to use gdk_event_unref,
not g_object_unref. Oops
Introduce GDK_DISPLAY_DEBUG() and GDK_DEBUG() and
the helper function gdk_debug_message(). This is
meant to clean up the mess of our current debug
statements which wildly mix g_message, g_print
and g_printerr.
The X11 backend can mark modifiers like Shift as consumed even if they
aren't actually active, which seems to be something to do with making
shortcuts like `<Control><Shift>plus` and `<Control>plus` work as
intended regardless of whether the plus symbol is obtained by pressing
Shift and a key (like `+/=` on American, British or French keyboards)
or not (like `*/+` on German keyboards).
However, this can go badly wrong when the modifier is *not* pressed.
For example, terminals normally have separate bindings for `<Control>c`
(send SIGINT) and `<Control><Shift>c` (copy). If we disregard the
consumed modifiers completely, when the X11 backend marks Shift as
consumed, pressing Ctrl+c would send SIGINT *and* copy to the clipboard,
which is not what was intended.
By masking out the members of `consumed` that are not in `state`, we
get the same interpretation for X11 and Wayland, and ensure that
keyboard shortcuts that explicitly mention Shift can only be triggered
while holding Shift. It continues to be possible to trigger keyboard
shortcuts that do not explicitly mention Shift (such as `<Control>plus`)
while holding Shift, if the backend reports Shift as having been
consumed in order to generate the plus keysym.
