This milestone tracks the tasks remaining to get to a point where the core GLTF scene viewing capabilities are satisfactory. They need not be feature complete, eg normal mapping, shadow mapping, skeletal animations, etc, are all huge epics that will need their own dedicated milestones, but shouldn't block us from building other stuff in parallel / before that.

Ideally, we would want the Damaged Helmet bug to be solved in this milestone, but it's an acceptable risk.

First collaborative milestone! The main goals are to get on the same page and establish best practices, while also doing some code cleanup from prototype code => robust + safe APIs along the way.

Now that facade runs bug free on both primary platforms, the hasty hacky changes are basically done, and we can shift focus to improving the existing code, including adding basic comments / docs.
