To do this, you need something like the rotate() method in
visad/examples/Test57.java, except you want to zoom instead
of rotate and you only want to do this once rather than
repeatedly. The 4th argument to make_matrix() is the zoom
factor. You'll need to experiment with values other than
1.0 for zoom, but use 0.0 for all other arguments.

Good luck,
Bill
