[Feature request]: Support finger-touch swipe scrolling of pages in PDFs also #1225

Is your feature request related to a problem? Please describe. On touch-screen devices, such as laptops and tablets, it is possible to scroll pages with a finger swipe in EPUBs, but not PDFs.

Describe the solution you'd like Make PDFs opened in Foliate also scrollable with a finger-swipe, not just by tapping using the bottom navigational arrow >

Additional context I do realize this may be a limitation of the underlying PDF parsing library. As a result, it may be harder to implement in Foliate.

Edit: On account of that, tapping > < navigational arrows to turn the pages seems significantly slower with PDF documents, than with EPUBs.

No, it's not a PDS.js problem. PDF.js is only used for rendering the pages themselves. Pagination is handled the same way as fixed-layout EPUBs, and currently the fixed-layout renderer is lacking many features.
