[Feature] Search for windows that are unmapped or visible on all desktops

As I understand it, xdotool search supports filtering of matching windows do a specific desktop... or not filtering by that criteria at all. Not all windows are associated with a specific desktop, however. So, unless I've misunderstood, there is no way to search for unmapped windows or sticky windows (windows that have been set to show on all desktops). The only way to accomplish this is to search for all windows, and manually filter out those windows that are associated with a desktop.

Consider this example:

  BASHCMD> for dtn in $(seq 0 $(./xdotool get_num_desktops)); do \
          for wid in $(./xdotool search --desktop $dtn --class .); do \
              echo "Desktop $dtn; Window $wid; Title: \"$(./xdotool getwindowname $wid)\""; \
          done; \
      done

I have one "unmapped" window and one "sticky" window, not shown above. The only way to find those with xdotool is to search for everything, like so:

  BASHCMD> for wid in $(./xdotool search --class .); do \
          echo "Desktop $(./xdotool get_desktop_for_window $wid); Window $wid; Title: \"$(./xdotool getwindowname $wid)\""; \
  done;

Note that in the foregoing, there are a ton of windows that are not on any particular desktop-- most of which belong to the window manager. Also note that in each of these cases, there's an error that gets generated, before I'm able to print the desktop value as "-1". Note also that I cannot do xdotool search --desktop -1 --class . -- as that does not work. So I'm stuck with a mass of output I don't want or need, and lots of manual work to do, and lots of error messages to get at the information I want.

It would be nice if xdotool search supported a variant of the --desktop option that would pick unmapped/sticky windows, and it would also be super-helpful if there was a way to filter out windows owned by the window manager (windows with _NET_WM_STATE that includes _NET_WM_STATE_SKIP_TASKBAR, _NET_WM_STATE_SKIP_PAGER)... Not sure how you'd want to present that in the interface, but it shouldn't be super-hard.
