Hi everyone,
I finally got back to working on the GLTF decoder, it's it's just about
done. I have a few more things to finish up after that, and I can merge
this in. Tests also need to be written as well. Writing the GLTF decoder
has clarified a few things, so I'm feeling fairly happy about it. It will
be a fairly simple implementation to start, but things can be expanded in
the future as we move to GL3+ (which I've also been working on :) ).
