Use case

In scenarios that we use LongPressDraggable, we might be needing to have an access to rootOverlay and hitTestBehavior. Even though, the parent class Draggable have these values at the current master channel, there is no access to either rootOverlay or hitTestBehavior.

Proposal

Add two new variables to LongPressDraggable constructor and pass them with the super call which will take these two variables directly to the parent class.

I will create a Pull Request to fix this problem.
