It started out as busywork, but it does many separate things. If I could
start over, I'd take them apart into multiple commits:
1. Remove G_ENABLE_DEBUG around GDK_DEBUG_*() calls
This is not needed at all, the calls themselves take care of it.
2. Remove G_ENABLE_DEBUG around profiling code
This now enables profiling support in release builds.
3. Stop poking _gdk_debug_flags and use GDK_DEBUG_CHECK()
This was old code that was never updated.
4. Make !G_ENABLE_DEBUG turn off GDK_DEBUG_CHECK()
The code used to
#define GDK_DEBUG_CHECK(...) false
#define GDK_DEBUG(...)
which would compile away all the code inside those macros. This
means a lot of variable definitions and debug utility functions
would suddenly no longer be used and cause compiler errors.
At the moment of launching/activating an application, the
keyboard focus may be on a transient surface that quickly
disappears after activation. If this happens, and the
compositor handles surface destruction before the activated
application gets to reply, the activation request may be
deemed outdated, and the "demands attention" paths be taken.
Peek the toplevel from the focus surface, as that has larger
guarantees to remain valid for the whole duration of the
operation.

The protocol spec isn't clear about the relationship
between the capability enum and the uint in the capability
event.
Fix things to use the same relationship as mutter.
This is implemented using a new xdg_toplevel `suspended` state, and is
meant for allowing applications to know when they can stop doing
unnecessary work and thus save power.
In the other backends, the `suspended` state is set at the same time as
`minimized` as it's the closest there is to traditional windowing
systems.
This mapping of stylus evdev input event codes into GDK button numbers
makes gdk/wayland inconsistent with gdk/x11, so depending on the backend
the same button middle-click pastes or right-click pops up menus.
Make the wayland backend consistent with X11, so that a GNOME wayland
session gets these buttons consistently mapped across all kinds of
clients.

We were creating the pad device on wp_tablet_pad.done, but
at that time we do not know what tablet it is associated with,
thus we cannot get appropriate vid/pid/name properties for it.
To get that, we need to wait for the pad to enter a surface,
at that time we do know what tablet it is associated with, so
we can get better information about the device.
There are pads that may plausibly "change" tablet between
one .enter event and the next (e.g. Wacom Express Key Remote),
but this situation is highly unlikely. The pad devices created
are thus persistent until that situation happens.
When GDK_DEBUG=no-vsync is on, we might have more than one outstanding
frame. Don't assert when that hapens. Just request a frame callback for
the first and skip the others.
... when it is available.
Also introduce the new function gdk_rectangle_transform_affine(), which
looks like overkill for this purpose, but I'm about to use it elsewhere.
There's no need for EGL to do any timing, we do it in GTK already.
This fixes hangs in Mesa when we hide a surface after a SwapBuffers()
but before the frame callback arrives.
If we then reshow the surface and immediately render to it, Mesa would
still have a frame callback from before the hiding and forever poll()
waiting for the compositor to send the callback.
Fixes#5761
That way, it doesn't ned a specific init function.
Also chain up last, so that the generic initialization code can access a
fully initialized wayland surface.
X11 does add an extra reference to surfaces that gets released when the
DestroyNotify event arrives.
Wayland doesn't ave such an event, so that reference never gets
released.
This fixes a copy/paste error introduced in commit 590f3dfa1f.
We want to remove the event queue from the list of event queues, not the
surface.
Otherwise the freed queue stays in the list and the next time an event
comes in, we access invalid memory.
Fixes thinko introduced in commit 7fafa5133b.
Luckily, we leak all surfaces, so this problem never occured.
We want to keep the wl_surface around, because surfaces create their
resources on construct and keep them until destroyed. See the HWND ond
Windows and the XWindow on X11.
This is relevant for graphics resources, where we want to have access
to the VkSurface and eglSurface while the GdkSurface is hidden.
We also want these surfaces to be permanent and not change during the
lifetime of the GdkSurface.
What we can - and must - destroy however are the xdg surfaces, because
those handle visibility on screen.
And we also need to ensure no buffer is attached, so that during the
next creation of the xdg surface we don't get a protocol error.
gdk_wayland_surface_maybe_resize() just calls
gdk_wayland_surface_update_size(), so make all callers call that one
instead.
The check that it does is done by the other function again.
This workaround - were it ever to trigger - is broken today. It destroys
the wl_surface and all associated structs but does not recreate the
xdg_popup or xdg_toplevel struct, so it would cause a hidden window.
The workaround looked a lot different when it was introduced in commit
83b54bab57, too - both in what it did and
in what the vfuncs did that it called.
Fractional scaling with the GL renderer is
experimental for now, so we disable it unless
GDK_DEBUG=gl-fractional is set.
This will give us time to work out the kinks.
This commit combines changes in the Wayland backend,
the GL context frontend, and the GL renderer to switch
them all to use the fractional scale.
In the Wayland backend, we now use the fractional scale
to size the EGL window.
In the GL frontend code, we use the fractional scale to
scale the damage region and surface in begin/end_frame.
And in the GL renderer, we replace gdk_surface_get_scale_factor()
with gdk_surface_get_scale().
