Hi Andreas,

I haven't had such a problem yet, so I don't know tools that perform the 
actual syntax highlighting. But what I do not understand is why you are 
using SVG and external graphics. FO is capable of doing preformatted 
text and also of colorizing text. So no need to go that path. Since you 
using scripts anyway (as far as I understand), it shouldn't be too 
complicated to generated XML fragments to be inserted into you document.
