Based on this release:

https://github.com/MetaCell/geppetto-meta/releases/tag/1.2.0

we'll need to test:

Big Image Viewer Example not working showcase
Updates VR Canvas to match with the latest changes on the MeshFactory component
Removes deprecated / inaccessible features from VR Canvas (Visual groups, geppetto mocked simulation, menu)
Removes unused variables from canvas engine
Remove tight dependency on ThreeJS repo for draco loader
Host big image viewer example

@simao please coordinate with Afonso as much of the stuff is from him.
