Subject: intel: Drop TEXTURE_RECTANGLE check in miptree layout setup.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6f31da584fd0c65095c325e60728f8230c66385a;p=mesa.git

intel: Drop TEXTURE_RECTANGLE check in miptree layout setup.

It's already handled by our non-mipmapped MinFilter, since
TEXTURE_RECTANGLE is always NEAREST or LINEAR.
