On a default Ubuntu 16.04 (xenial) installation, GTK3 applications (which include most of the default GUI applications) have smooth scrolling activated. How do I disable it?

The same behavior occurs in the file selection dialog box, in Nautilus, etc. How do I turn off smooth scrolling, i.e. how do I make the PageUp/PageDown keys show the previous/next page immediately?
