| 1. A graphics display system comprising a display including a plurality of pixels, each pixel having a X coordinate and a
Y coordinate and data therefore wherein the plurality of pixels generate a gradient on the display, and the data for each
pixel including a fast-clear bit that indicates if the data of that pixel is ignored in a pixel data operation on the system,
wherein if the pixel data is ignored, a clear value of the pixel is used to maintain the gradient on the display without a
constant refresh of the pixel data, wherein the clear value is dependent on at least one coordinate of the pixel.
