Title: Pinch to zoom [WIP]

This is a WIP to implement pinch to zoom functionality for PDF.js. It uses the gesture detector from Gaia. See https://github.com/mozilla/pdf.js/issues/2582 for more details.

I have opened this PR in particular to be able to generate previews to test on mobile devices where I can actually test pinch to zoom. ;-)
