Subject: primconvert: select pv convention only from flatshade_first
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1cdb01d716cb8112c67f8538f7d71d0765153eb2;p=mesa.git

primconvert: select pv convention only from flatshade_first

This should match to how drivers program hardware. flatshade relates to
whether color inputs are interpolated, not the provoking vertex
convention.
