Comment 9 for bug 1703690

please find enc two revised patches that hopefully take into account Laney and Lukasz comments.

gnome-desktop3 is very much simplified to explicitly check the draw_background key from the background schema. Note - I haven't included a new changelog for this debdiff.

gnome-screensaver reworks to define the in_desktop check via its own module "gs-common.h/c". The in_desktop check simplifies the code as per Laney's recommendation.
