+- Change gtk2-devel BuildRequires to gtk3-devel since the code
+  using GTK+ has been ported.
+- Add explicit glib2-devel BuildRequires, so we can version it.
+- Add pkgconfig(xv) BuildRequires on openSUSE > 12.1: this used to
+  be pulled in by something else, but the relayout of xorg-x11
+  packages changed that. Pull in conditionally only to not risk
+  breakage in linked OBS instances (pkgconfig() was not supported
+  in older openSUSE releases).
