package Aspect

        ---Version:

        ---Purpose: This package contains the group of graphic elements common
        --          to different types of visualisers. It allows the description
        --          of a screen background, a window, an edge, and groups of
        --          graphic attributes that can be used in describing 2D
        --          and 3D objects.

        ---Keywords: Window, Aspect, FillArea, Line, Marker, Edge
        --           Highlight, Hatch, Background, GradientBackground, Color map,
        --           Type map, Width map, Font map
