Comment (by Shelob9):

 I uploaded a patch 26386.2.diff​ that adds the filter I was talking about.
 Here is example usage:

      add_filter('custom_background_style', 'slug_full_screen_bg', 10, 2 );
      function slug_full_screen_bg( $style, $background ) {
      if ( $background != '' ) {
      $style = "background-repeat: no-repeat; -webkit-background-size:
 cover;-moz-background-size: cover;-o-      background-size: cover
 ;background-size: cover;background-attachment:fixed;background-
 position:center;";
      $style .= " background-image: url('$background');";
      }
      return $style;
      }

 This example, to be used in a theme or plugin, creates a full-screen
 background if an image is set in custom backgrounds, and just outputs the
 background-color rule and value if none is set.
