| 1. A graphics display system comprising:
a data structure memory;
a graphics processor for processing graphics images to be displayed on a display;
a data structure stored in the data structure memory, the data structure for defining a corresponding one of a plurality of
logical surfaces on which the graphics images are arranged, at least one of the graphics images including pixels of a single
color, the data structure comprising:
a field indicating a relative depth of the corresponding one of the logical surfaces;
a field indicating a location of the corresponding one of the logical surfaces on the display; and
a field indicating a color of the corresponding one of the logical surfaces, wherein the pixels for the graphics image including
pixels of the single color are generated by the graphics processor using the color indicating field by applying the single
color to the corresponding one of the logical surfaces.
