Fix generation of axis_stop events

Browse source 
`axis_stop` should only be sent if the value is `Some(0)`, while this
also sent it for `None`. So every scroll event on one axis generated
stop events for the other.

This fixes scrolling with a touchpad in Alacritty.

Anvil already does this, comparing against `Some(0.0)`.
