 660            window to emulate the richedit control, is that normally, the
 661            WM_NCCALCSIZE message window would return the client area of the
 662            edit control.
 663
 664            While we could send a message to the edit control here to get that size
 665            and return that value, this causes problems with the WM_SIZE message.
 666            That is because the WM_SIZE message uses the returned value of
 667            WM_NCCALCSIZE (via X11DRV_SetWindowSize) to determine the size to make
 668            the edit control. If we return the size of the edit control client area
 669            here, the result is the symptom of the edit control being inset on the
 670            right and bottom by the width of any existing scrollbars.
 671
 672            The easy fix is to have WM_NCCALCSIZE return the true size of this
 673            enclosing window, which is what we have done here. The more difficult
 674            fix is to create a custom Richedit MoveWindow procedure for use in the
 675            WM_SIZE message above. Since it is very unlikely that an app would call
 676            and use the WM_NCCALCSIZE message, we stick with the easy fix for now.
