Subject: i965: Drop strict conformance fallback for GL_LINE_STIPPLE.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e9868979c5373501234392a38a786d5a92dc47b5;p=mesa.git

i965: Drop strict conformance fallback for GL_LINE_STIPPLE.

We implement line stipples, just not *quite* correctly.  We have a
piglit testcase to use when we want to fix it, if we do.  Until then,
don't lie to our test suites.
