[Mesa-dev] [PATCH] draw: initialize prim header flags when clipping lines

[sroland at vmware.com]

From: Roland Scheidegger <sroland at vmware.com>

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.)
