Resize images in user guide pdf?

[bmcrae]

We can easily create narrower margins with pandoc (e.g. use command:

pandoc -V geometry:margin=1in --smart -o circuitscape_4_0.pdf t1.tex

but I'm not sure how to preserve the image sizes. It would be nice to do this, since we get lots of page breaks as currently implemented. I suppose we could redo images and add white space on either side if needed.

This seems to be an open issue in pandoc for quite some time now. They seem to have some patches that are not yet accepted. I think we should wait.
