Set the length of the string, padding with the supplied character if the supplied string is shorter than desired, or
truncating the string if it is longer than desired. Unlike {@link #justifyLeft(String, int, char)}, this method does not
remove leading and trailing whitespace.

@param original the string for which the length is to be set; may not be null
@param length the desired length; must be positive
@param padChar the character to use for padding, if the supplied string is not long enough
@return the string of the desired length
