Claim Text:
1. A computer implemented method of buffering an application image comprising: providing the application image separated into a plurality of tiles; determining which of the tiles are overlapped by a viewport, wherein the viewport identifies a visible portion of the application image, and the visible portion is smaller than the application image; buffering the tiles overlapped by the viewport in a front buffer and a back buffer, wherein the visible portion of the application image is extracted from the front buffer, the application image is modified in the back buffer, and the front buffer and the back buffer are in a computer-readable memory; and buffering the tiles not overlapped by the viewport in the back buffer in which the application image is modified but not in the front buffer from which the visible portion of the application image is extracted even when the front buffer and the back buffer are flipped in a buffer flip.
