vector graphics
     
         (Sometimes called "object-oriented" graphics,
        though it's nothing to do with {object-oriented programming}).
        The representation of separate shapes such as lines, polygons
        and text, and groups of such objects, as opposed to {bitmaps}.
        The advantage of vector graphics ("drawing") programs over
        bitmap ("paint") editors is that multiple overlapping elements
        can be manipulated independently without using differenet
        layers for each one.  It is also easier to render an object at
        different sizes and to transform it in other ways without
        worrying about image {resolution} and {pixels}.
