Bug#904910: override: libgnomecanvas:oldlibs/optional, libgnomecanvasmm2.6:oldlibs/optional

[Simon McVittie]

Package: ftp.debian.org
Severity: normal
X-Debbugs-Cc: libgnomecanvas at packages.debian.org, Adrian Bunk <bunk at debian.org>, libgnomecanvasmm2.6 at packages.debian.org

libgnomecanvas is no longer part of GNOME and is dead upstream (the last
upstream non-translation commit was in 2011). Its removal from Debian
was proposed by the GNOME team, but Adrian Bunk has expressed interest
in adopting it, so it might remain in Debian for buster.

libgnomecanvasmm2.6 is a C++ binding for libgnomecanvas which seems
equally dead.

Please move all of those two source packages' binary packages to oldlibs
to reflect their upstream maintenance and deprecation status.

Thanks,
