Re: [Algorithms] Sorting triangles

[Jason Z. <zi...@n-...>]

Yeah we use alpha test, but the edges still flicker with the bad sorting so
its pretty much just as noticable if it was off.  As Nils said earlier, its
better to have a more stable sort order than a correct order, and ours right
now is pretty unstable.

I've got some good ammunition to try a few new things, thanks to everyone's
suggestions.
