[Dri-devel] Mesa 4.x and culling

The mach64 driver with Mesa 3.x was using code like this (borrowed from utah-glx) to cull primitives: xx[0] = (GLint)(v0->v.x * 4); yy[0] = (GLint)(v0->v.y * 4); xx[1] = (GLint)(v1->v.x * 4); yy[1] = (GLint)(v1->v.y * 4); xx[2] = (GLint)(v3->v.x * 4); yy[2] = (GLint)(v3->v.y * 4); /* calculate
