[Bf-committers] Particle experiments - looking for feedback

Would it not be simple enough to detect this case and treat it as two 
triangles? Or just to treat all quads as two triangles to unify the 
code? [i've not looked at the patch as reblended.com seems to be down 
just now, so i don't know how feasible this is with how it's 
implemented]. Just a thought... :)

The possibilities for this are really cool- good work :)
