I just answered some of this. Plotting to a pdf, the pmd3d files are 70%
larger. And it looks like pm3d re-interpolated the original data, which
I don't want, and which shouldn't be needed, since I already have
regularly-spaced matrix data.

So the question that remains is the one about making 'with image'
produce colors AND z
