Description
While working on a new sample requiring me to render a complete glTF scene I noticed that the glTF loader for the api samples is severely limited. It can only load (and display) a single mesh with a single primitive from a glTF file. That's a real hindrance and something we should address near-term. It also does not apply any matrices, so scenes aren't scaled properly.
Sadly the glTF loader initially taken from my code has been partially wired to the framework, making it non-trivial to fix this without needing to change a lot of things.

Research direction
Locate the glTF loader used by the API samples and inspect how it currently handles a single mesh, primitive, and scene matrices. Done means the loader can load and display complete glTF scenes, including multiple meshes or primitives, with scene scaling and other matrices applied.
