apitrace file i965

Ilia Mirkin found some application bugs, these have been fixed and a new trace
has been recorded on i965. It does not fix the issue however.

Through some testing we've found that merely writing to gl_ClipDistance will
break the geometry shader. Even when GL_CLIP_DISTANCE0 has been disabled and
such writes should be ignored according to the spec.
