The relative distance that must be travelled before the gesture automatically completes.

The default when Type != Active is 1, meaning the user must travel, or swipe with enough velocity, to cover the full distance. When Type == Active the default is 0.5, meaning the panel will automatically open/close when the half-way point is reached.

A separate value for activation and deactivating can be specified. The first value of the float2 is the activation threshold, and the second value the deactivation threshold.
