wmdrawer Depends on packages from gdk-pixbuf-xlib, which is no longer
maintained upstream and has been archived, meaning that issue reports
and contributions are no longer accepted.

The readme of the archived project says:

    No newly written code should ever use this library.

    If your existing code depends on gdk-pixbuf-xlib, then you're strongly
    encouraged to port away from it.

This deprecation applies to <gdk-pixbuf-xlib/*.h> and the
gdk-pixbuf-xlib-2.0 pkg-config module, which means the
libgdk-pixbuf-xlib-2.0-dev and libgdk-pixbuf-xlib-2.0-0 Debian packages.

wmdrawer seems to have a runtime dependency without having a
build-dependency - I'm not sure I understand how that works. Perhaps an
obsolete dependency has been hard-coded? Please investigate whether this
can be removed during the forky cycle.

Thanks,
