Unfortunately this will load an image, upload it to X and return a
Render Picture ID, but it does not apply it as the desktop wallpaper.
It's a utility service used by hildon-desktop.

There is no API for setting the background from an external process,
feel free to fill a feature request in bugzilla.

Regarding general look and feel of the desktop, everything is in
~/.osso/hildon-desktop/*.conf (number of panels, panel configuration ...).
But the theming is quite relying on the default configuration.
