Don't (mouse-position) or (mouse-pixel-position) give the current position
when you install the timer?

Do we really need that option?

That's what I think should be the default ... don't select the window until
the mouse movement stops.  But detect that quickly!

Can't you just use a (fixed) 0.1 second timer the first time ?

No.  One timer "mouse-movement-stopped-timeout" would be ok.
