Well, there is SVG Terminal:


One interesting thought experiment:

* Suppose TeXmacs' PS-Device had a Cairo backend (which would be a very 
  useful thing to have in any case.)
* Cairo already has an SVG backend, suppose that backend could be made 
  to perform well. Suppose further it could be made to modify the SVG
  document incrementally.
* Serialize the Cairo's changes to the SVG Term protocol and you get a 

Well, yes this is science fiction as of now. But, maybe we could start
small and implement a cairo backend for TeXmacs...?  :)
