Subject: [PATCH] Added a ServerWindow::ScreenChanged() hook, which takes care
 of resizing an eventual offscreen directwindow and sends the direct window
 notifications (not yet, though, since a BDirectWindow on a non-visible
 workspace would get the B_DIRECT_START notification and start drawing on a
 different workspace).
