[OpenLayers-Users] Hover control sample (share)

[Alexandre Dube]

Hi Eric,

  I took a look at the SelectFeature control.  Now I understand what you 
meant and it makes sense.  Also, it's also making sense to have this 
control have the possibility to highlight on hover or on click.

  "beforefeaturehighlighted" and "featurehighlighted" events make sense, 
but a "featureunhighlighted" (or some other term meaning that the 
feature was highlighted and is now no more) would also be useful.
