Ok with little understanding of tessellation shaders I sent out this
patch set as an alternative to this change in the hope on getting some
more of the arrays of arrays pieces in. But after seeing the next patch
in the series I'm not 100% sure if its still suitable. Anyway I've
already sent it out and don't have time to look over this again until a
few days time so thought I'd point you to it anyway.
