* INLINE FUNCTION: HwndMsWheel
* Purpose : Get a reference to MSWheel Window, the registered messages,
*           wheel support active setting, and number of scrollLines
* Params  : PUINT puiMsh_MsgMouseWheel - address of UINT to contain returned registered wheel message
*           PUINT puiMsh_Msg3DSupport - address of UINT to contain wheel support registered message
*           PUINT puiMsh_MsgScrollLines - address of UINT to contain Scroll lines registered message
*           PBOOL pf3DSupport - address of BOOL to contain returned flag for wheel support active
*           PINT  piScrollLines - address of int to contain returned scroll lines
* Returns : HWND handle to the MsWheel window
* Note    : The return value for pf3DSupport and piScrollLines is dependant
*           on the POINT32 module.  If POINT32 module is not running then
*           the values returned for these parameters will be
*           FALSE and 3, respectively.
