Hi Timothée,

I just happened to be sitting down with Eric Anholt and looking
closely at the results of cairo's test suite with recent X server
builds. He found a failure in the X implementation of saturate, and I
felt guilty for remembering that you had reported this earlier and we
hadn't done anything about it.

Anyway, he's looking at this now so hopefully we can see a fix for
this soon.
