Hi Katie,
That's a good idea so I just implemented it. In tonight's build there will be 
support for a viewpoint tag in ISL. You can do 3 things - set the aspect ratio 
of a view, set the tilt/azimuth (like you can do with the Viewpoint dialog) and 
explicitly set the rotation/translation/scale matrix.

Attached is an example isl file that shows these 3 things.

I have also added to the Aspect Ratio tab of the View manager properties dialog 
a listing of the rotation/scale/translation values. So you can easily figure 
out for a given viewpoint what the values are.

Please give us some feedback on this and feel free to make suggestions for 
improvements.

-Jeff
