Well, I have done a quick test - see attached files - which are
screenshots of Illustrator after 'placing' the PDF and PS versions of
some random Analysis spectrum.
The PS and PDF versions look basically the same, like this: figure.png
However, when you do a 'select all' then the pdf and ps versions show
some differences: pdf_AI.png and PS_AI.png.
Note that we now also see 'invisible' parts that were hidden due to
clipping. The PS version really does look quite different and I found
them to be much easier to use.

Well, from looking at a zoomed in version of the PS (zoomed.png) it
would seem that this is exactly what is happening in the postscript
version already.
