[Mesa-dev] [RFC 0/6] Add support for ARB_transform_feedback_overflow_query.

[Rafael Antognolli]

This patch series is an initial version that implements support for
ARB_transform_feedback_overflow_query on i965. It does that by storing
the initial values of generated and written primitives on glBeginQuery,
and final values on glEndQuery, and then comparing those values.

I still need to write piglit tests for it, so it's not very tested, but
the basic functionality seems to work fine. Any feedback is welcome.

Thanks,
Rafael
