FOP uses the same resource dictionary for all the pages? That must be a really 
old FOP version, I hope.

It's not that difficult. Parse the content stream with PdfContentParser and 
build a list of all the xobjects (the ones with the 'do' command). Compare this 
list with the resource and eliminate xobjects not needed. Call 
PdfReader.removeUnusedObjects() to clean the pdf and use PdfStamper to output 
the result.
