Music to my ears.

For @white-space-treatment="preserve", modify your whitespace munging
template to not apply to FOs with @white-space-treatment="preserve".
xmlroff preserves whitespace by default.

@background-image would probably be pretty simple (much simpler than
fo:external-graphic): in theory, you'd modify area-to-pdf.c to do the
FoDoc calls to render the background image before doing the FoDoc
calls to render the text.  You may also have to implement FoDocGP
functions to render the image, but how hard can that be?
