Subject: i965: Use a line end cap width of 0.5 unless smooth lines enabled.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b6d56c747cbce7b9ca297be1c6f2c2b7ca91842d;p=mesa.git

i965: Use a line end cap width of 0.5 unless smooth lines enabled.

This updates the Gen4-5 code to use a line end cap width of 0.5
for non-smooth lines, and 1.0 for smooth lines - which is what we
do on Gen6+.
