 * overwrite the default properties of the new file.  Applications are
 * encouraged to use this function in order to provide a uniform style.  The
 * command line arguments provided are the <em>type</em> of the cell values, the
 * <em>precision</em>, the properties of the <em>compression</em>, and the
 * dimension of the tiles (<em>tiledimension</em>). Every of these values
 * defaults to the value described in RASTER3D Defaults. This function has to be
 * used in conjunction with Rast3d_getStandard3dInputParams()
