        Bug 546739 â Introspection should know precise signal parameter types

        * giscanner/annotationparser.py:
        * tests/scanner/annotation-1.0-expected.gir:
        * tests/scanner/annotation-1.0-expected.tgir:
        * tests/scanner/annotation.c (annotation_object_class_init):

        Annotations are parsed for signals, the (type) annotation is introduced.
