! Returns this range, possibly modified to not exceed the bounds provided as \a lowerBound and \a upperBound. If possible, the size of the current range is preserved in the process. If the range shall only be bounded at the lower side, you can set \a upperBound to \ref QCPRange::maxRange. If it shall only be bounded at the upper side, set \a lowerBound to -\ref QCPRange::maxRange. */
