  44  * Testing:
  45  *   - Run tests using Waite Group Windows95 API Bible Volume 2.
  46  *     The second cdrom (chapter 3) contains executables activate.exe,
  47  *     curtool.exe, deltool.exe, enumtools.exe, getinfo.exe, getiptxt.exe,
  48  *     hittest.exe, needtext.exe, newrect.exe, updtext.exe and winfrpt.exe.
  49  *
  50  *   Timer logic.
  51  *
  52  * One important point to remember is that tools don't necessarily get
  53  * a WM_MOUSEMOVE once the cursor leaves the tool, an example is when
  54  * a tool sets TTF_IDISHWND (i.e. an entire window is a tool) because
  55  * here WM_MOUSEMOVEs only get sent when the cursor is inside the
  56  * client area.  Therefore the only reliable way to know that the
  57  * cursor has left a tool is to keep a timer running and check the
  58  * position every time it expires.  This is the role of timer
  59  * ID_TIMERLEAVE.
  60  *
  61  *
  62  * On entering a tool (detected in a relayed WM_MOUSEMOVE) we start
  63  * ID_TIMERSHOW, if this times out and we're still in the tool we show
  64  * the tip.  On showing a tip we start both ID_TIMERPOP and
  65  * ID_TIMERLEAVE.  On hiding a tooltip we kill ID_TIMERPOP.
  66  * ID_TIMERPOP is restarted on every relayed WM_MOUSEMOVE.  If
  67  * ID_TIMERPOP expires the tool is hidden and ID_TIMERPOP is killed.
  68  * ID_TIMERLEAVE remains running - this is important as we need to
  69  * determine when the cursor leaves the tool.
  70  *
  71  * When ID_TIMERLEAVE expires or on a relayed WM_MOUSEMOVE if we're
  72  * still in the tool do nothing (apart from restart ID_TIMERPOP if
  73  * this is a WM_MOUSEMOVE) (ID_TIMERLEAVE remains running).  If we've
  74  * left the tool and entered another one then hide the tip and start
  75  * ID_TIMERSHOW with time ReshowTime and kill ID_TIMERLEAVE.  If we're
  76  * outside all tools hide the tip and kill ID_TIMERLEAVE.  On Relayed
  77  * mouse button messages hide the tip but leave ID_TIMERLEAVE running,
  78  * this again will let us keep track of when the cursor leaves the
  79  * tool.
  80  *
  81  *
  82  * infoPtr->nTool is the tool the mouse was on on the last relayed MM
  83  * or timer expiry or -1 if the mouse was not on a tool.
  84  *
  85  * infoPtr->nCurrentTool is the tool for which the tip is currently
  86  * displaying text for or -1 if the tip is not shown.  Actually this
  87  * will only ever be infoPtr-nTool or -1, so it could be changed to a
  88  * BOOL.
