Scale GEOM-ID, multiplying its size by FACTOR. The factors
should be positive numbers. If FACTORY and FACTORZ are
present and non-zero, the object is scaled by FACTOR in x, by
FACTORY in y, and by FACTORZ in z. If only FACTOR is present,
the object is scaled by FACTOR in x, y, and z. Scaling only
really makes sense in Euclidean space. Mouse-driven scaling in
other spaces is not allowed; the scale command may be issued
in other spaces but should be used with caution because it may
cause the data to extend beyond the limits of the space.
