Subject: i965/fp: Set coord_components correctly for cube textures.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=62050886c85b7b3b6c94e3c2363966b4f14df0bd;p=mesa.git

i965/fp: Set coord_components correctly for cube textures.

I've no idea why this was 4.  It certainly seems wrong.

Prevents assertion failures in fp-incomplete-tex with some upcoming
patches of mine.
