The sub-pixel adjustment for points was killed off in
commit 60d762aa625095a8c1f9597d8530bb5a6fa61b4c
Author: Xiang, Haihao <haihao.xi...@intel.com>
Date: Wed Jan 2 11:38:51 2008 +0800
i915: Needn't adjust pixel centers. fix #12944
so if we don't need it in intel_tris.c we don't need it in
intel_render.c either, which means we can allow
intel_render.c to render points.
