If we can set Gnome wallpaper without ot be relevant of any GTk libraries,
it will be safe so far. Using dbus is the right way.

This can be a solution for all other linux desktop which do not support
dbus interface.

For info, this is the GThumb wallapaper tool code :

https://github.com/GNOME/gthumb/tree/d644a77a1b2085ce2c947719fb3f9107e068c42c/extensions/desktop_background

As i can see, GThumb is able to set wallpaper properties as centered,
tiled, adapted, etc. This can be a plus for the digiKam plugin.
