So I'm not very familiar with the eps writer (John Wise added this
functionality added the ability to use SlicePlot and ProjectionPlot), so
take what I'm saying worth a grain of salt.

I think the solution is to pass in multiple different SlicePlot and
ProjectionPlot instances.

See this page in the docs:

http://yt-project.org/doc/visualizing/plots.html#publication-ready-figures

Unfortunately I won't have time to look into this more closely in the next
day or two.
