"...and stay dead!"
Rafael deleted this file in c2b5a26dc2
(i965: Convert SF_STATE to genxml.) but Marek accidentally brought it
back in commit e7a091936f (mesa: replace
ctx->Polygon._FrontBit with a helper function) when resolving conflicts.
It's not actually even compiled, but it's still here trolling people
into thinking it still exists and needs patching.
