commit d978a05e9d2eca893c3d0623d2370cc89f51c841
Author: Alexander Mikhaylenko <alexm gnome org>
Date: Sun Jun 30 17:15:44 2019 +0500
windowManager: Use SwipeTracker
Replace existing four-finger gestures with SwipeTracker.
Since TouchpadWorkspaceSwitchAction and WorkspaceSwitchAction are now
unused, remove them.
Change programmatic workspace transition to use easeOutCubic interpolator
to match the gesture.
Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/756
