ResolverObject (re)entry point.
This cannot be made a call to a virtual function because virtual functions do not like NULL and checking for NULL everywhere is more cumbersome than this little helper function.
group | the group to resolve for |
object | information needed to resolve the group |
top_level | true if this is a top-level SpriteGroup, false if used nested in another SpriteGroup. |
