        /* A fundamental problem with embedding an edit control within another
           window to emulate the richedit control, is that normally, the 
           WM_NCCALCSIZE message window would return the client area of the 
           edit control.
           
           While we could send a message to the edit control here to get that size
           and return that value, this causes problems with the WM_SIZE message.
           That is because the WM_SIZE message uses the returned value of
           WM_NCCALCSIZE (via X11DRV_SetWindowSize) to determine the size to make 
           the edit control. If we return the size of the edit control client area
           here, the result is the symptom of the edit control being inset on the 
           right and bottom by the width of any existing scrollbars.
           
           The easy fix is to have WM_NCCALCSIZE return the true size of this 
           enclosing window, which is what we have done here. The more difficult 
           fix is to create a custom Richedit MoveWindow procedure for use in the 
           WM_SIZE message above. Since it is very unlikely that an app would call
           and use the WM_NCCALCSIZE message, we stick with the easy fix for now.
