Image resolution for PDF

Hi,

The recent changes to the way the documentation is generated has resulted in
reduced quality images in the PDF version. On screen they look fine, but
printing them results in -- how do I say this nicely -- sub optimal prints
;-)

I noticed a commit where all images were reduced to 96dpi and a max
width/height of 500/800. This results in a max effective image width in the
PDF of 5.2 inch (13 cm).

Isn't it possible to render the images as 200dpi (or 150dpi) in the PDFs?
With a max width of 13 cm, that should allow images of up to 1040 (or 780 at
150dpi). For printouts that results in much clearer images.

I would lend a hand in debugging the FOP/Docbook stuff to see where the
image resolution is set. A pointer towards the file(s) to start with would
be great.
