<P>The document is represented by a tree of graphics objects. The document
consists of one or more layers. Each layer consists of zero or more
primitives or compound objects.</P>
<P>Primitives are the leaves of the tree and contain no other graphics
objects, examples are Rectangles or PolyBezier objects. Most primitives
can have line and fill properties (Text objects currently can only have
fill properties and image objects have neither fill nor line
properties).</P>
<P>Compound objects are graphics objects that contain other graphics
objects, examples are the ordinary Group or the BlendGroup.</P>
