Description:
Scales the drawing sections shown in one or more windows by a factor. A
factor greater than 1 shows a bigger part of the drawing (the first mouse
stroke applies a factor 2), a scale factor less than one shows a smaller part
(the second mouse stroke applies a factor 0.5).
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.
