  1. To tell if the mouse is inside a screen, use the (query-mouse)
  function, and check the return values against the size of the screen.
  Remember that (epoch::screen-height) and (epoch::screen-width) take an
  optional screen argument, as does (query-mouse).

Actually, I would have to check (equal (query-mouse) (query-mouse
screen-I-want-mouse-to-be-on)), and check the screen size.  But this
isn't fully reliable ...

When I do C-h f query-mouse I get:

  Query the location of the X-window cursor. Returns the list (X Y MOD-STATE). Character coordinates

What is the "MOD-STATE"?
