     *  Notes:
     *  - In the Editor folder because WebGL doesn't like ProceduralMaterial types.
     *  - Named pb_ObjectArray because this was initially intended to be a base type for
     *    other save-able object types. It is only used for materials, but changing the name
     *    to something more suitable would mean breaking existing material palettes for
     *    lots of people.
