-/**
- * The CompileState holds information used during a compile.  It is
- * passed to each SceneGraphObject (SGO) during the compile.  Each SGO
- * modifies the CompileState as necessary and passes the CompileState
- * to its children (if any).
- *
- * The CompileState currently has two functions: appearance mapping
- * and shape merging.
- *
- * Appearance mapping maintains a list of the unique appearances seen
- * during the compile.  getAppearance() is used to turn multiple,
- * equivalent and static appearances into a single shared appearance.
- *
- * The shape mergings collects shapes that are potentially mergable
- * during a compile.  The shapes are sorted into a Map of Lists of
- * shapes, using the shape's appearance as the key.  After a subtree
- * is traversed, the shapes are merged and added to the Group.
