// that mouse movement during that interval doesn't move the cursor
// and events carry a constant location (the warped-to position)
// even though they have delta values. This screws us up because
// the accumulated deltas we send to Wine don't match any eventual
// absolute position we send (like with a button press). We can
// work around this by simply forcibly reassociating the mouse and
// cursor position.
