/* Cannot use TrackMouseEvent, as the stupid WM_MOUSELEAVE message
 * doesn't tell us where the mouse has gone. Thus we cannot use it to
 * generate a correct GdkNotifyType. Pity, as using TrackMouseEvent
 * otherwise would make it possible to reliably generate
 * GDK_LEAVE_NOTIFY events, which would help get rid of those pesky
 * tooltips sometimes popping up in the wrong place.
 *
 * Update: a combination of TrackMouseEvent, GetCursorPos and 
 * GetWindowPos can and is actually used to get rid of those
 * pesky tooltips. It should be possible to use this for the
 * whole ENTER/LEAVE NOTIFY handling but some platforms may
 * not have TrackMouseEvent at all (?) --hb
