Summary

0002213: s3o support for triangle strips is broken

Description

I encountered this bug while using a script to convert 3do-s to s3o-s.
I couldnt, for the life of me figure out why my s3os crashed upspring if I had models with tristrips. I tried both strips and fans, both crashed upspring (correct vertice orders were verified with a manual .obj conversion).
Oddly, spring loaded these s3os, but didnt render them properly, see picture. It did, however, seem to render pentagons right, it failed on quads and hexagons.

This is highly non optimal, and may result in us pushing many times the triangles required (since piece shares primitive size to all primitives in piece, any piece with a single more than 4 sided face will be split into triangles)

Fixed in non-GML builds; the NV_primitive_restart extension must be present.

However, as said, your converted armcom does not render correctly even when it is.
