Description:
Shows the rectangular part of a source window in one or more destination
windows. It should be noted that source and destination can refer to the
same window (which is the approach of the two point mouse stroke).
A window can be identified by a digitized point or by typing its
identifier. Since the identfiers are powers of two (e.g. 1, 2, 4, ...) a set
of windows can be defined by adding the identifiers (e.g. 1+2+4). The set
of all windows is described by the identifier -1.
