touchHandling.js extra use cases

[JayPanoz]

Just recording my thoughts but a handful of existing features in other Reading Apps came to my mind when closing the UX issue in Readium CSS:

• opening table in a dedicated web view/modal when double-clicking/double-tapping it;
• opening figure/img in a dedicated web view/modal when double-clicking/double-tapping and/or pinch-to-zooming – I’ve never quite understood why the figcaption is ignored when it is available though;
• when handling links, there’s also linear="no" documents;
• it’s not uncommon apps are also using pinch to zoom to change the font-size.

What do we want to do for those ones, and possibly others I can’t recall right now?

BTW is highlighting implied?
