handlesGroupEvent
Whether this holder should react to event when it's broadcast via TileRenderingScope.dispatchGroupEvent. The default implementation never matches anything — override it (typically with a type check against your own TileGroupEvent subtype, optionally comparing a group-identifying field) on a TileHolder that participates in a group concern.
Return
true if this holder should receive event via onTileGroupEvent.
Parameters
event
the group event to test.
