Abstract
A graphics sub-system manages a two-dimensional coordinate space which includes a plurality of rectangular regions. The two-dimensional coordinate space is represented by a hierarchical linked list of nodes. Each node represents a rectangular region of two-dimensional coordinate space. Each node acts as a bounding box for all descendant nodes in the hierarchical linked list of nodes.
