Support retina icon marker with scaledSize property

I think we should try to use this option with scaledSize for Icon :
https://developers.google.com/maps/documentation/javascript/examples/ico...

I would also be interested in placing an additional image for retina displays. Are there already plans on integrating this feature?

Also interested, it would be very nice to have an option to set a scaledSize value via UI.
Meanwhile, something similar to this works:

var icon = {
   url: map_locations[0].pin,
   scaledSize: new google.maps.Size(42, 64)
}
for (j in map_locations) {
  var marker = new google.maps.Marker({
       position: new google.maps.LatLng(map_locations[j].lat , map_locations[j].lon),
       map: map,
       html: map_locations[j].popup,
       icon: icon,
       original_icon: map_locations[j].pin,
       active_icon: map_locations[j].pin,
       category: map_locations[j].category
  });
  // more code

Changed to feature request.

Adjusted title and changed to a feature request on 8.x, as 7.x will just be maintenance only from now on.

I suggest the default implementation to support the scaledSize and Size property automatically to be 2x.
As we would need it to be compatible with a map consisting of multiple pins (with different markers). Allowing different sizes would complex the UX, so in case this would be really necessary later on request. We can think of a more advanced implementation.

Added to the latest dev release for field formatter and view style.
