[OpenLayers-Users] Selecting a feature AND drawing a point

[ibarkley]

In the feature class there exists a 'geometry' class that contains a
LineString: pretty much [x1,y1,x2,y2,],[]..]; the start,end for each vertex
on the feature. these coordinates are in whatever coordinate system the base
layer is in, but you can use the map object and 'getViewPortPxFromLonLat()'
or something similar to construct a Pixel object....
