Carl J. Bialorucki 3e46a8673d [EXPLORER][COMCTL32] Fix balloon tooltips and system pager alerts (#5559) 
- [EXPLORER] Set maximum balloon width for notification area
- [COMCTL32] Fix balloon tooltip shape

- Limit balloon tooltips from extending past the edges of the monitor, not the edges of the work area.
- Instead of simply repositioning the main rectangle when the balloon is too far towards one edge of the screen,
  try flipping the balloon the other way. This is the same behavior as Windows Server 2003.
- Tweak some values used to draw the balloon tooltips to more closely follow the Windows balloon tooltip style.
- Removing trailing whitespace.
- While the new changes are guarded, consider cancelling our Wine sync for common controls.
  Our common controls are responsible for many graphical issues and lack of features throughout ReactOS.

*
* 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.
