    libview: checking if point is inside annotation
    
    Added a step to check if a point is inside an
    annotation. In case it is foud to be inside the
    bounding box, view asks the document if it is
    actually inside the annotations, since the
    quadrilaterals might not comprise the whole are of
    the bounding box. Only then it become selectable.
