title: Mouseover range/distance
body: <p>Is there anyway to change default mouseover range? Simple example, I have a map with a bunch o tracks which are 1-2 px wide and are clickable. To click a track and display info you need to click very precisely which can be very annoying. Is there any way to change that tolerance? Just to show what I mean here's my example.
  Thanks in advance.
