Hum, probably as a WMS output format, a cross between SVGMapProducer
and the default raster output. From the former I would take the approach
to encode stuff directly in a text format (see SVGEncode.java), from the
latter the code needed to compute a transformation (both scale and
eventually reprojection, see StreamingRenderer.java in GeoTools) and to
generalize polygons so that your image map does not get containing
houndreds of thousands of points (see Decimator.java, again in GeoTools).

Yep, exactly what I was talking about (and remember to register the
factory into applicationcontext.xml or it won't be picked up).
Hope this helps
