4 * Project: TIFF Overview Builder
5 * Purpose: Library functions to maintain two rows of tiles or two strips
6 * of data for output overviews as an output cache.
7 * Author: Frank Warmerdam, warmerdam@pobox.com
8 *
9 * This code could potentially be used by other applications wanting to
10 * manage a once-through write cache.
