21  * NOTES
22  *
23  * This code was audited for completeness against the documented features
24  * of Comctl32.dll version 6.0 on Sep. 08, 2004, by Robert Shearman.
25  *
26  * Unless otherwise noted, we believe this code to be complete, as per
27  * the specification mentioned above.
28  * If you discover missing features or bugs please note them below.

30  * TODO:
31  *   - Custom draw support.
32  *   - Animation.
33  *   - Links.

43  *
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.
