zoom in at a focus point
zoom out at a focus point
a WorldMap object
a Reference to the GeoNames dataset
a list representing a point
The ZoomIn command zooms in the view with respect to some focus point.
If only m is given, the focus point will be the current view center.
If ref is supplied, ref must contain exactly one row, so that it corresponds to exactly one point.
If a point p is supplied, p will be the focus point for zooming in.
p must be a list of two elements. The first element in p is the longitude (x-coordinate in the Geographic projection), and the second element in p is the latitude (y-coordinate in the Geographic projection).
The ZoomOut command zooms out the view with respect to some focus point.
If a point p is supplied, p will be the focus point for zooming out.
