OK, by git bisect I've noticed that this isn't a regression in between 
9.2 and 9.2.2! The problem is because in my latest dashboard builds I'm 
using

    --with-osmesa-bits=32

which is how I usually deploy osmesa because we zbuffer precision issues 
in the past. Removing this option this tests all pass again.

Unfortunately I don't know how long this option has been a problem since 
the few VTK dashboards that test Mesa have never as far as I know built 
withh 32 bits. :-(

does this help you guys at all?
