OptionaltargetA map of GraphObject target properties to Theme objects. This determines where a lookup will occur for a given property. For example, one might map Shape.fill to the colors object via "fill" -> "colors".
If not defined, or a target property is missing, some sensible defaults are provided.
An interface describing a theme.
The various optional properties this interface provides are the default object names used to lookup some binding target properties. For example, Panel.padding is looked up in the margins object and Shape.strokeWidth and GraphObject.opacity are looked up in the numbers object.
While the indexer can be used for other arbitrary objects, we suggest using the optional named properties here for their respective purposes.
