+//      Saves image i in an OpenEXR file with name n.  The file will be
+//      tiled if the image has more than one level, or if a header, h, is
+//      given and contains a tile description attribute; otherwise the
+//      file will be scan-line based.  The file will be deep if the image
+//      is deep; otherwise the file will be flat.
+//
+//      If header h is given, then the channel list in h is replaced with
+//      the channel list in i, and the levelMode and the levelRounding mode
+//      fields of the tile description are replaced with the level mode
+//      and the levelRounding mode of i.  In addition, if the data window
+//      source flag, d, is set to USE_IMAGE_DATA_WINDOW, then the data
+//      window in the image is copied into the header; if d is set to
+//      USE_HEADER_DATA_WINDOW, then the data window in the header is
+//      replaced with the intersection of the original data window in the
+//      header and the data window in the image.  The modified header then
+//      becomes the header of the image file.

+//      Note: USE_HEADER_DATA_WINDOW can only be used for images with
+//      level mode ONE_LEVEL.
