*       ZMOUSE.H - Include file for MSDELTA Zoom mouse DLL. 
*
*       REVISIONS - 
*        April 1996 - removing WM_MOUSEWHEEL, this
*             message will only be available via the OS.  Applications
*             must now register the message MSH_MOUSEWHEEL, and
*             use that message for messages from MSWHEEL.  
*        May 1996 - Added add'l #defines for class and title of the wheel
*                      module window to reflect the MSH_ style.
*                    - Added #defines for WHEEL SUPPORT and Scroll Lines
*                    - Added inline function HwndMsWheel, apps can use
*                      this function to retrieve the handle to mswheel,
*                      get the message ID's for the registered messages,
*                      the flag for 3d support, and the value for scroll
*                      lines. Please in function at end of file.
