Primitive restart, with a non-0xff/0xffff/0xfffffffff cut index
Unsupported geometries? (lineloop, etc)
In these cases the submitted geometry has to be rejigged [in the VBO module] so instead of doing nice pipelined setup of an indirect draw, we'll have to stall, map the indirect BO, yank the draw parameters out, and munge them CPU-side.
At least:
