Hello ... when I select to a new screen, I don't ALWAYS want it raised
automatically.  Usually I only want it raised iff either the cursor is
not visible, or the mouse is not over the new screen.  Is there a way to
tell this within epoch?  That is, to know, for the current screen, if
the mouse is over the screen, and/or if the portion of the screen that
shows the text cursor is visible.  Is this possible?  How?

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).

2. I don't think you can tell if the text cursor is visible, since
there is no way to determine X window stacking order from inside
Epoch.
