This is probably a completely stupid and bonkers idea... but I wonder
whether using Inkscape's ability to be able to export PDF or PS files
that can be imported into LaTeX and let LaTeX deal with the text
placement/rendering would work...  Rather fiddly for just a "give me
an image" library though :)
