Subject: i965: Drop strict conformance fallback for GL_POLYGON_SMOOTH.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d8b733643d21001068c25ee9b97a3cd5bb4684a2;p=mesa.git

i965: Drop strict conformance fallback for GL_POLYGON_SMOOTH.

From my reading of the GL 2.1 spec, no antialiasing is strictly
conformant for polygon smoothing.  Yes, it's absurd, but then,
hardware doesn't support this so maybe it's not so absurd.
