Does the Marker Clusterer support custom icons? It seems to work fine
whenever I am not usual a custom icon for my markers. As soon as I add
in custom markers, I get an error when zooming in. I believe the error
is triggered when a marker is removed from a cluster but I cannot say
for sure since I am new to using marker clusterer.
The error I see is...
ArgumentError: Error #2025: The supplied DisplayObject must be a child
of the caller.
