I'm looking for an event that fires while you are editing a Polyline in Google Maps, similar to the 'drag' event on Markers. I've found the 'capturing_changed' event, but it seems to fire on dragstart and dragend, not on drag. As is I'm having to reinvent the wheel by allowing a Marker to be dragged and updating the Polyline based on where the Marker is, basically reinventing editable Polylines. I'd like to be able to add Markers, which editable Polylines do smoothly, but I have to be able to detect on drag. I can't find anything in the API documentation or on a Google search, so I thought I'd ask here.
