another solution might be a recursive triangle clipper which is easy to code once you got your ultra-fast triangle filler :). however, there are worst-case situations where a simple triangle gets subdivided into huge counts of small ones....but as i said the method is quite intuitive and you can completely skip the edgebuffer (+ z-clipping becomes possible).
here's an implementation example (a bit messy though):
http://www.mactech.com/articles/mactech/Vol.15/15.06/3DGraphicEngineEssentials/
regarding the z-clip i've experienced performing z = (z<zmin? zmin : z) during your hidden-surface removal (don't forget to reject triangles with each vertex' z<zmin) to produce sufficient results while being unbeatable in performance.
and here are some small hints for the CS-line clipping algo:

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
