The function is fundamentally broken for unbounded surfaces.
If a surface is unbounded, we cannot represent this as a
cairo_rectangle_int_t, and using the return value doesn't work because
it's already used for something else.
In GTK3, unbounded surfaces aren't a problem, but GTK4 uses recording
surfaces.
So better remove that function before we keep using it and using it
wrong.
We're not in the business of adding Cairo APIs. That's Cairo's job.
Also, we don't need this API anywhere like the original commit claimed,
so there's no need to make it available in any way.
This reverts commit afa6cc2369.

This renames the GdkWindow class and related classes (impl, backend
subclasses) to surface. Additionally it renames related types:
GdkWindowAttr, GdkWindowPaint, GdkWindowWindowClass, GdkWindowType,
GdkWindowTypeHint, GdkWindowHints, GdkWindowState, GdkWindowEdge
This is an automatic conversion using the below commands:
git sed -f g GdkWindowWindowClass GdkSurfaceSurfaceClass
git sed -f g GdkWindow GdkSurface
git sed -f g "gdk_window\([ _\(\),;]\|$\)" "gdk_surface\1" # Avoid hitting gdk_windowing
git sed -f g "GDK_WINDOW\([ _\(]\|$\)" "GDK_SURFACE\1" # Avoid hitting GDK_WINDOWING

Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.
The functions gdk_pixbuf_get_from_window() and
gdk_cairo_set_source_window() are unreliable and depend on the windowing
system (they work great on X11 and Win32, less so on Quartz and Wayland).
With the switch to new drawing API and OpenGL, we can definitely no
longer support a generic way to snapshot windows.
People should either write windowsystem-specific code or draw their
widgets directly - like with gtk_widget_draw() - if they need to get a
rendering.
Don't try to paint onto an error surface. This happens for example when
gdk_cairo_set_source_pixbuf() is called with a pixbuf that is too big
for Cairo to handle.

The documentation explicitly states that 0 is an allowed value for using
the same scale as the window. This 0 value is also explicitly checked
down in the call chain and handled.
gdk_cairo_region_create_from_surface doesn't work correctly on PPC.
This is most prominently seen with the GTK window resize grip, the
shape of which is mirrored every eight pixels horizontally.
At the same time, use an A1 surface for the resize grip shape to
eliminates an A8->A1 surface conversion.
... instead of _gdk_drawable_ref_cairo_surface() where appropriate.
Also, don't implement the drawable->create_cairo_surface vfunc anymore.
This is in preparation for the split of GdkWindow from GdkDrawable.
This is not strictly an API change as GdkDrawable is typedeffed to
GdkWindow, but it changes the header, so I'm marking it as such.
gdk_cairo_create() can only be used with windows these days, so it makes
sense to pass a window. With that, we can alseo remove the
set_cairo_clip() vfunc from GdkDrawable and implement it inside
gdkwindow.c.
You should not ever ever ever call cairo_reset_clip(). If you do, your
code is broken and you deserve everything you get.
And we should definitely not support this insanity.
GdkRGBA is a boxed struct similar to GdkColor, with the difference
that it stores alpha information as well, and colors are stored in
[0..1] doubles, in the cairo spirit.
gdk_cairo_set_source_rgba() has been also added to allow easier handling
of this new type.
