Looks like it's calling draw_primitive_immediate_mode(), which isn't going to
work with core contexts. Looking over the patch set, I think it may be doing
that because in draw_primitive() it sets "emulation = TRUE;" if
"use_indexed_vertex_blending(state, stream_info) &&
use_software_vertex_processing(context->device)".
