FTR dEQP has been "fixed" (by removing the test all together) to not
generate the above error. At the same the Pixman equivalent is still
buggy, hence the v2 of commit
df8efd5b74d45e2bfb977a92dcd3db86abd6b143.

I've sent patches [1] to restore the test and fix the buggy ones.

As those land, I would love to have symmetrical Window/Pixman paths. Be that:
 - merging this patch (with polished commit message), or
 - updating the Window path to be like this one.

I have no preference on which one ;-)

Thanks
Emil
