Photo that shows the rendering issue on Heaven (notice the black lines on the right screen and the wrong colors next to the street light)

The commit "i965: Hook up L3 partitioning state atom." (http://cgit.freedesktop.org/mesa/mesa/commit/?id=228d5a3f75086e92aaa01619a55d6c8ac7841e0e) introduced a rendering regression in at least heaven and lightsmark (where I first spotted it).

The rendering issue also bleeds to other contexts as can be see on the attached screenshot which confirms the bisection.

The attachment type got mis-detected. Fix it.

Information about the hw and libraries used

Sorry for not having the version the libgl and other mesa libraries, I installed the binaries myself and not through ezbench, so it did not get added to the shaderDB. I have an alias in my .bashrc to do the install and add the libs in shaderdb but I forgot to use it.

This patch from curro[1] fixes the rendering issue.
