Bug#976677: gdk-pixbuf-xlib: is deprecated

[Simon McVittie]

Source: gdk-pixbuf-xlib
Version: 2.40.2-2
Severity: important
Tags: confirmed upstream wontfix

gdk-pixbuf-xlib has been deprecated by its upstream developer. The README
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.

See https://gitlab.gnome.org/Archive/gdk-pixbuf-xlib for more details.

The Debian GNOME team plans to release gdk-pixbuf-xlib in Debian 11
'bullseye' (expected in mid 2021), but it will not necessarily be released
in Debian 12 (expected in 2023).

We also want to phase out the libgdk-pixbuf2.0-0 and libgdk-pixbuf2.0-dev
transitional packages at some point. Again, we intend to release them
in Debian 11, but hopefully not in Debian 12. There will probably be a
mass-bug-filing for packages that depend on the transitional packages.

To replace those transitional packages, packages that depend on the main
gdk-pixbuf library (the gdk-pixbuf source package) should (build-)depend
on libgdk-pixbuf-2.0-dev, libgdk-pixbuf-2.0-0 or gir1.2-gdkpixbuf-2.0,
whichever is appropriate.

Packages that depend on this deprecated Xlib integration should
additionally (build-)depend on libgdk-pixbuf-xlib-2.0-dev or
libgdk-pixbuf-xlib-2.0-0.
