Thank you @t11r for submitting this pull request and we look forward to adding TIFY to the list of viewers. There were a couple of recipes that we didn't think TIFY supported:

• Image disapears in this example: 🔗 0014-accompanyingcanvas but it should be shown while the audio is playing.
• 0035-foldouts the second "foldout folded" canvas should be shown alongside the title page not as an individual

We thought TIFY supported this recipe but it wasn't listed:

• Also add to Example 2: viewingDirection top-to-bottom in book-2-viewing-direction

And we took the following notes which won't stop us merging the pull request:

• 🔗 0234-provider doesn't include a link to the Provider seeAlso but OK to merge.
• 🔗 0283-missing-image we see error dialog but shows the last image that was looked at. Would be nicer if it showed a broken image like it does for the thumbnails.

Thank you for reviewing, @glenrobson! I added TIFY to the second example of 0010 and removed it from 0014 and 0035. I will add those with a separate PR once the issues are fixed.

Thanks for the changes. Merging.
