dim_id	IN:	Dimension identifier returned by SDgetdimid
	scale_buf	OUT:	Buffer for the scale values

	Purpose	Retrieves the scale values for a dimension.
	Return value	Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.
	Description	SDgetdimscale retrieves the scale values of the dimension identified by the parameter dim_id and stores the values in the buffer scale_buf.
		SDdiminfo should be used to determine whether a scale has been set for the dimension, i.e., that the dimension scale data type is a valid HDF data type (not 0). Also use SDdiminfo to obtain the number of scale values for space allocation before calling SDgetdimscale.
		It is not possible to read a subset of the scale values. SDgetdimscale returns all of the scale values stored with the given dimension.
