Earlier this year I wrote a short article for XML.com called "XSLT and
Image Rendering"
http://www.oreillynet.com/xml/blog/2008/06/xslt_and_image_rendering.html
introducing the idea of rendering SVG
graphics using XSLT 2.0 and outputting the result as a TIFF image. The
render makes use of a 'partial' XSLT implementation of the Reyes
Rendering Pipeline.
If you've got an idle five minutes you might want to amuse yourself
with a quick look.
