Thanks for your feedback and for your patch. As agreed on IRC with you
and Holger, we’ll look at including such a change in the Jessie branch
instead of introducing a build change a few days before we release

Instead of degrading the image quality while resizing it directly, I’d
prefer to just display it with a reduced size, as done in the wiki
(<img  […] width="800">). I don’t know yet how to introduce that with
our DocBook sources, but we’ll see.

That should not be needed: we already take care of the images size of
the PDF in documentation/common/pdf.xsl:

<xsl:param name="imagedata.default.scale">maxwidth=15.5cm,maxheight=12cm</xsl:param>
