/* A fundamental problem with embedding an edit control within another

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.
