Subject: util/u_blitter: Set pipe_sampler_state::normalized_coords correctly.
X-Git-Tag: mesa-9.2.1~2582
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fdb88967e3a1d559fa522afa8336446e92330ff2;p=platform%2Fupstream%2Fmesa.git

util/u_blitter: Set pipe_sampler_state::normalized_coords correctly.

We might want to revisit the normalized_coords semantics, but this is
the current expected behavior.

Fixes fdo bug 61091.
