Subject: draw: initialize prim header flags when clipping lines
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9db7309595309ff0835c701108827ffc8c906751;p=mesa.git

draw: initialize prim header flags when clipping lines

Otherwise, clipped lines would have undefined stippling reset bit if line
stippling is enabled.
(Untested, and I just assume copying over the bits from the original line
is actually the right thing to do.)
