title: Does region.contains() include the boundaries?
body: <p>I was wondering if I created a square region using four paths and if I want to check if the user has clicked that region with Region.contains(). What happens if a user clicks on one of the paths(the boundaries)?</p>
  
  <p>I ask this because I'm creating many regions next to each other using paths and when they click a certain region a specific sound to that region should trigger but what if they touch an intersection?</p>
