Subject: i965: Enable lower_clip_distance.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b9ef2b85b41272da9ed95071307310f9749cbf2b;p=mesa.git

i965: Enable lower_clip_distance.

i965 requires gl_ClipDistance to be formatted as an array of 2 vec4's
(as opposed to an array of 8 floats), so enable the lowering pass that
performs this conversion.
