Hi Veksler,
Right now there is no way to write over the decorations provided by the
windows managers and since many flavors of window managers exist, I think
that's something we shouldn't try to do.

In managed windows, there are still some parts of the non-client area to
which we can write (the menu bar for example). Only the decoration provided
by the window manager (caption, border) are not accessible. This can be a
problem because a managed Wine window starts just below the window managers
decorations. However, this keeps the code a lot more simple :)

Yes, that's the x11drv part, however this knowledge is also shared
throughout the Window structure using the WIN_MANAGED flag.

At the current time, you can check at the Wine level if a windows has
decoration with the flag WIN_MANAGED (wndPtr->flags & WIN_MANAGED).
