[Bug 37864] When I resize a maximized MDI window it assumes the new size instead of remaining maximized

--- Comment #1 from [e-mail] ---
More info on the SizeWindowForScreenDimensions() function - which is where the
problem's really happening.

All it does is call GetWindowPlacement(), update the rcNormalPosition rectangle
in the WINDOWPLACEMENT struct and then call SetWindowPlacement() to change the
position rect.  I verified that the WINDOWPLACEMENT showCmd field returned by
GetWindowPlacement() is 3 (SW_MAXIMIZE).  When I call SetWindowPlacement with
showCmd of SW_MAXIMIZE, it should remain maximized.  I think that's where the
WINE bug is.  After that call, the MDI child window size and position reflects
the new rcNormalPosition, but the window is still technically 'maximized'
(i.e., the MDI child buttons appear both on the menubar and on the MDI child's
titlebar).  And if I click on a second MDI child (now visible, because the
original one isn't properly maximized), it comes up maximized, and everything's
okay from there on - until it happens again after the next transaction.
