        * app/vectors/gimpanchor.h
        * app/vectors/vectors-types.h: Anchors now have an enum as type and
        have the "selected" property.

        * app/vectors/gimpstroke.[ch]
        * app/vectors/gimpbezierstroke.c
        * app/vectors/gimpvectors-preview.c: Additional functions to get
        information about the graphical representation of the stroke and be
        able to select anchors.

        * app/tools/gimpvectortool.c: semi-usable interface, better graphical
        representation of what is going on. Also make use of the "selected"
        property of the anhors to just display a subset of the control
        handles.
