title: Openlayers how to show polygon only on mouseover, and hide on mouseout?
body: <p>Any suggestions on how i can show a polygon only on mouseover? I am thinking it must be possible to set the initial fillOpacity and strokeOpacity to 0 on the style object.</p>
  
  <p>And then attach a mouseover and mouseout listener to the polygon itself, and modify the fillOpacity and strokeOpacity style upon invocation of the listeners?</p>
  
  <p>However, im a bit stuck on actually how to get started with this.</p>
  
  <p>Any guidance and help is appreciated!</p>
