Refresh overlayMapTypes (i.e. force call getTile for visible tiles)

[Lewis Diamond]

Hi all,
I have a custom overlayMapType which will add markers from inside the
getTile function. However, this custom map type can be modified to
render different subsets of the markers. In this case, I have to clear
all the markers from the map and then add only the relevant ones.
However, after removing all the markers, I have no mean to trigger a
refresh on the map (i.e. have the map call getTile on my overlay for
every visible tiles).

Does anyone know how to force the refresh of overlay tiles?

Thanks,
Lewis
