    gnome-bg: Fix color conversion for solid backgrounds
    
    gnome_bg_create_surface converts the primary background
    color of a background without a filename from a GdkColor
    to a GdkRGBA.  It does it incorrectly though.
    
    This commit divides each color component by 65535 instead
    of 255, since GdkColor uses 16-bit color values.
