Subject: replace FbRootWindow::depth with maxDepth

The depth member of FbWindow was abused to store the maximum depth
but that gets overridden with geometry changes of the root window
(screen layout changes) so we store and read the value explicitly while
::depth() maintains the actual depth of the root window

The result of this is that frames for ARGB windows were created with a
wrong depth and failed to reparent the client window.
