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. --HG-- extra : rebase_source : 9e56fd40929257d847c5cddb8a998c3ca2381655
