The create/VIE/Backbone port is taking place in parallel in the D7 and D8 versions of this module.
D7 - branch: node/1808076-createjs-d7 - this issue
D8 - branch: node/1824100-createjs-d8 -
The difference between the two branches should boil down to how the libraries are included. We're pushing for create.js and VIE to be included in D8 Core. For D7, we need to include these libraries in the module.
