as far as I'm concerned, Batik uses it's own font-rendering system, right?
Well not really. We have two main text rendering paths. The first uses the AWT GlyphVector classes to render text (this is for most normal text), the second essentially renders text as shapes (this is primarily used for SVG Fonts which lack font hinting of any kind anyways).
Would it be possible to plugin 3rd party rendering engines, like Adobe CoolType, Bitstream's Font Fusion, Agfa's iType et al?
This is software, anything is "possible", but in this case I think it would be extremely challenging. First it would involve a lot of JNI (Java Native Interface) since those all sound like traditional 'C' libraries. Second you would have to significantly rework the current gvt.font package to be more dynamic in choosing implementations.
It would also be a big change switching to drawing 'bitmaps' instead of 'shapes'. I also suspect that there might be some issues around resolution dependent layout (right now we essentially don't account for the fact that the bounds of rendered text may change when the user to device transform changes).
It would be interesting work as currently Batik's font rendering is not nearly as good as I would like to see, but this would not be a very 'clean' solution - since it would involve native code.
Has somebody done this already?
Not to my knowledge. I'm a little surprised you didn't mention FreeType, as at least that is Open Source.
