That's great thanks Matt. Chris Forbes has also offered to help so I
guess I'll cc you both :)

Here is some extra comments I sent to Chris on those two patches:

The geom shader tests are mainly just tests taken from the glsl 1.50
compile tests and extended for arrays of arrays. I've made some
reasonable assumptions where the spec doesn't provide full detail. As
you can see from the results the Nvidia and AMD drivers do not always
follow the spec even when it does provide full detail.

As for the varying packing test I understand that arrays of
arrays is not really a glsl-1.10 test but this test also contains tests
for 1.20 and 1.30 so I figured I'd add arrays of arrays too rather than
duplicating the code elsewhere. I'm happy to pull this out and make it
into a stand alone test though. It would also make it possible to clean
it up a bit. The way arrays support works seems a little messy, and my
changes for arrays of arrays add to this, but then again its not likely
to need to change again much in future.
