Filters that are arranged before the drutex filter, are ignored when PDF:s are generated.

I run into this problem because allowing MediaWiki syntax (With the use of PEAR Wiki filter) with Latex support as an option (primarily used for math formulae).

I'm converting all the wiki-syntax to true latex syntax with the help of custom regex-replacement filters created with the flexifilter module, arranged before the drutex filter, so that what is passed to drutex is pure latex.

This works perfect for display of the node in the browser, but not in the generated PDF, where instead the unprocessed wiki-code is appearing, without formatting.
