Bug#856027: mate-desktop: "solid color" for background does not work at all

[Vlad Orlov]

Various background issues, caused by changes in GTK+ 3.22, had been fixed
upstream. The following packages are needed:

mate-desktop 1.16.2
mate-settings-daemon 1.16.2
caja 1.16.3


Since Caja 1.16.3 requires build and runtime deps on mate-desktop 1.16.2,
the following change to debian/control is suggested:
