/**

This function deallocates an existing GeoTIFF access handle previously
created with GTIFNew().  If the handle was
used to write GeoTIFF keys to the TIFF file, the
GTIFWriteKeys() function should be used
to flush results to the file before calling GTIFFree().  GTIFFree()
should be called before XTIFFClose() is
called on the corresponding TIFF file handle.<p>
