limit object relative distance

[maksad]

Currently, I am using your package and its great. everything works good and it simple to init. The only thing is that I didn't get how to limit the parallax. for example when an object assigned to be parallax (parallax parallax-ratio="-0.25") the object keeps moving until the end of the entire scroll. How can I limit the travel distance for example to 100px?

This is something that's not currently built in, but would be useful.
