Get and Set the value of the current zoom level

To get the current value of the scene zoom use: >>echo zoom() To set current zoom to a certain value use: >>zoom(eval(Value-zoom())) This can be used to put different structures on the same scale. Note that a value of 1 corresponds to the scale where the smallest dimension of the screen view is 1 Angstrom. To reset zoom to default for the current model use: >>gl.zoom
