+ * 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.
