Formerly, the annotation layer interface provided the GrAnnotation library as a parameter to the `annotate` method. This was so the layer would not necessarily need to import the library at the module level and instead could use it as a utility toolbox. With this change, the library is no-longer part of the interface and the layers are now expected to import it at the module layer (if they have a use for it).
