When?

Well, I had exactly this one:
* view as/export to PDF (pdflatex)? <- rather unlikely!
It had driven me mad - why the heck LyX tries to convert a PDF
graphics to PNG when using pdflatex. In the end I switched to EPS as
graphics format.
I would like to use the pdf figures directly, is it possible?
How?
Set the right converter in Tools>Preferences>Converters
I have e.g. here on my Debian Gnu/Linux system:
PDF (ps2pdf) -> EPS pdftops -f 1 -l 1 -eps $$i $$o
Well, in the case of using PDF images in a document compiled with
pdflatex there should be no converter, right?
I guess, my problem was more related to the "Document format" and
"Vector graphics format" check boxes in the "File formats" preferences
pane. I have checked them for *all* PDF formats -- now it seems to
work.
However, I would like to understand the algorithm behind all this. I
understand the general: if a graphics format is attributed as some
"Vector format" the back-end compiler is able to understand, LyX gives
its precedence over conversion to a bitmap format.
However, what exactly is the format here? I have at least four
different "file formats" defined for PDF. Which one is taken into
account for the decision?
