--- Comment #4 from Mathias Fröhlich <Mathias.Froehlich at web.de> ---

Hi,

I can't remember why I thought there must be a minus.
Today this looks rather wrong to me ...
So I think that the proposed change to mesa is a good one.

Also I have checked out the provided test case on nvidias binary
driver which also aligns with James expected behaviour.

I believe that the piglit tests don't uses non zero y values for
the viewport. May be we want to add a test there also.

Greetings

Mathias
