This will let us use a subset of the full texture, which can
be necessary in the case that converters put padding around
content in dmabufs. The naming follows the Wayland viewporter
spec.
For now, make all callers pass the full texture rect.
We are going to introduce another rect, so better to be clear in
naming. We are following the naming of the Wayland viewporter spec
and call the rectangle that we drawing into the dest(ination).
Random code can call that function and cause unexpected GL context
changes. This is especially bad because it can happen nested.
Fixes the NGL renderer breaking in the inspector when importing a dmabuf
initializes the dmabuf backend which creates a GL renderer which creates
a GL context and makes it current causing the NGL renderer to break when
it continues rendering.

Expose information about if an event is handled to the backends.
This will allow a backend to deal with unhandled events, such as
macOS' default key bindings.
The first time this function is called, has_xdg_output() returns
true, but haven't yet received all the xdg-output events, so wait
for that to be done. Otherwise, the logical size is 0, and nothing
useful comes from that.
This fixes a problem that is apparent in
https://bugzilla.mozilla.org/show_bug.cgi?id=1869724, but that also
reproduces on any GTK application as described in
https://bugzilla.mozilla.org/show_bug.cgi?id=1869724#c16.
xdg_output sizes might be physical if the compositor doesn't scale them,
it seems. So to report the correct logical geometry in GDK pixels, we
need to detect this case. We do this by checking whether the wl_output
size matches the xdg_output size.
According to the Mesa developers, the correct way to determine
disjointness is to check the actual inode of the fd because dup()ing can
cause these duplications to happen when planes are carelessly copied or
when planes are sent over dbus or other unix sockets.

We keep various pieces of double-buffered state on our side,
and then explicitly sync it over to the Wayland side.
Add a function to find out if we have any.
The ngl renderer has good support for fractional scaling, so we
can enable this by default now.
If you are using the gl renderer, you can disable fractional
scaling with the
GDK_DEBUG=gl-no-fractional
environment variable.
When a toplevel is focused programmatically and there is no
underlying seat, we cannot attempt to focus it with no
focus to be obtained, nor serials serials to use.

In GLES, BGRA is still done by GL_EXT_texture_format_BGRA8888 which is
an extension that is older than GLES 2.0.
And back then, internal formats had to be specified unsized. And when
that was changed with GLES3, nobody updated the extension.
However, on OpenGL, this extension doesn't exist, and internal formats
need to be sized.
So let's use different internal formats depending on GL version.
Fixes#6333
Whether or not switches include shapes to indicate their ON/OFF
state is currently controlled by the stylesheet (in particular
the HighContrast style).
However there are use cases for both using the HighContrast style
without shapes, and for using shapes with the regular stylesheet,
so follow the newly added "show-status-shapes" setting instead.
