Chris H-C 53663750f7 Bug 506815 - Replace MouseTrailer with TrackMouseEvent. r=jimm
MouseTrailer, using a 200ms timer, was used to track whether a pointer was
still present over a window.

Windows has, since Windows 2000, offered to do this for us via an API called
TrackMouseEvent. (It'll also give us hover timings and non-client area versions
if we want)

I'm all for having Windows do the work for us, and it'll save us from waking up
the main thread five times a second.
