Subject: nvc0: multiply polygon offset units by 2
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1579017b08f28d460e17de65bcc8ba17ba695c37;p=mesa.git

nvc0: multiply polygon offset units by 2

Wasn't sure if this still was necessary because the piglit test
started to fail at some point on nv50 where we already do this.
