Subject: i965: Fix up texture layout for small things with wide pitches (tiled)
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6c3f6968911e0bb3256e91b070166d3da78a4775;p=mesa.git

i965: Fix up texture layout for small things with wide pitches (tiled)

We were packing according to the pitch, while the hardware appears to base
it on the base level width.

With this and the previous commit, fbo-cubemap now matches untiled behavior.
