Comment 1 for bug 2023367

I doubt simply disabling swiping would allow you to use third party
extensions since they likely assume they have control of touch input,
which will interfere with the calibre viewer's assumption that it
controls touch input in many different ways. If you can confirm that
it would actually work I might be motivated to implement this. You can
test it by running calibre from source and making adding an early return
to the handle_gesture() function in iframe.pyj

See https://manual.calibre-ebook.com/develop.html for how to run calibre
from source.
