All balls are colored in wrong colors.

I'm pretty sure that I had no such issue with i915 driver (on same machine with
same Mesa version), but I have no machine with i915 hw anymore, so can't check.
Anyway, foobillard++ on i965 Mesa driver (with Ivy Bridge hardware) has same
issue, so probably it's an application bug.</pre>
