We normally go by what the spec says and it doesn't say anything about what
happens if samples is zero. Later versions of the spec fix the issue so we go
by what that says.

Also I don't believe this change has anything to do with the piglit failure you
are seeing, mesa was updated to the same behavior as the piglit test you will
need to be more specific about the problem you are trying to solve here
