Not necessarily. The correct framebuffer needs to be bound for
subsequent draws, but that may very well be a different framebuffer
than the one currently bound. Invalidating STATE_FRAMEBUFFER ensures
that context_apply_draw_state() will bind the correct framebuffer even
if the bound render targets didn't change since the previous draw.
