Detailed Description

Defines a indexed primitive.

Indexed primitives are drawing primitives that are defined by an array of horizontal coordinates. They can be used for drawing various arbitary shapes, a circle for instance consists of two indexed primitives, one defining the right edge and other the left edge.
