* NOTES
*
* This code was audited for completeness against the documented features
* of Comctl32.dll version 6.0 on Sep. 08, 2004, by Robert Shearman.
*
* Unless otherwise noted, we believe this code to be complete, as per
* the specification mentioned above.
* If you discover missing features or bugs please note them below.
*
* TODO:
* - Custom draw support.
* - Animation.
* - Links.
* - Messages:
* o TTM_ADJUSTRECT
* o TTM_GETTITLEA
* o TTM_GETTTILEW
* o TTM_POPUP
* - Styles:
* o TTS_NOANIMATE
* o TTS_NOFADE
* o TTS_CLOSE
*
* Testing:
* - Run tests using Waite Group Windows95 API Bible Volume 2.
* The second cdrom (chapter 3) contains executables activate.exe,
* curtool.exe, deltool.exe, enumtools.exe, getinfo.exe, getiptxt.exe,
* hittest.exe, needtext.exe, newrect.exe, updtext.exe and winfrpt.exe.
*
* Timer logic.
*
* One important point to remember is that tools don't necessarily get
* a WM_MOUSEMOVE once the cursor leaves the tool, an example is when
* a tool sets TTF_IDISHWND (i.e. an entire window is a tool) because
* here WM_MOUSEMOVEs only get sent when the cursor is inside the
* client area. Therefore the only reliable way to know that the
* cursor has left a tool is to keep a timer running and check the
* position every time it expires. This is the role of timer
* ID_TIMERLEAVE.
*
*
* On entering a tool (detected in a relayed WM_MOUSEMOVE) we start
* ID_TIMERSHOW, if this times out and we're still in the tool we show
* the tip. On showing a tip we start both ID_TIMERPOP and
* ID_TIMERLEAVE. On hiding a tooltip we kill ID_TIMERPOP.
* ID_TIMERPOP is restarted on every relayed WM_MOUSEMOVE. If
* ID_TIMERPOP expires the tool is hidden and ID_TIMERPOP is killed.
* ID_TIMERLEAVE remains running - this is important as we need to
* determine when the cursor leaves the tool.
*
* When ID_TIMERLEAVE expires or on a relayed WM_MOUSEMOVE if we're
* still in the tool do nothing (apart from restart ID_TIMERPOP if
* this is a WM_MOUSEMOVE) (ID_TIMERLEAVE remains running). If we've
* left the tool and entered another one then hide the tip and start
* ID_TIMERSHOW with time ReshowTime and kill ID_TIMERLEAVE. If we're
* outside all tools hide the tip and kill ID_TIMERLEAVE. On Relayed
* mouse button messages hide the tip but leave ID_TIMERLEAVE running,
* this again will let us keep track of when the cursor leaves the
* tool.
*
*
* infoPtr->nTool is the tool the mouse was on on the last relayed MM
* or timer expiry or -1 if the mouse was not on a tool.
*
* infoPtr->nCurrentTool is the tool for which the tip is currently
* displaying text for or -1 if the tip is not shown. Actually this
* will only ever be infoPtr-nTool or -1, so it could be changed to a
* BOOL.
