No Pinch to Zoom

[sonicSMASH]

Description

Pinch to Zoom gestures don't work. My touchpad is capable of this, and other apps supposedly support it. I've tried it with firefox (using the MOZ_XINPUT_2 variable) and DevHelp and they will zoom in when pinching on the touchpad.

Note: the system is X11, but uses libinput for pinch gestures

Steps to reproduce the bug

1. Enable CTRL to Zoom in Drawing Preferences.
2. Try to zoom on the touchpad.
3. Only CTRL + moving fingers like a scroll wheel works.
