Getty documentation comments

• General usability: it would be useful if there were affordances for mobile scrolling and touch-trap(s) or mousewheel and/or documented approaches for managing this – scrolling through the documentation with a mouse, and/or on mobile trapped the user in the Zoomable interface
• This may already be part of the content yet to come, but I would love to see a brief discussion about componentization, design decisions, and ways of thinking about handling Vault data in the context of Vue and/or React – something a bit broader than the specific Vue example.
• There are still a bunch of “todos” and broken examples, it’s important to have these filled out before completion (TC)
• It would be useful to have JSdoc style api documentation as well as this: general documentation identifying all the methods that can be called on the ImageService and CanvasPanel.
