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