Bug Description:
TitledBorder's minimum size is not big enough for its title

The TitledBorder JavaDoc for getMinimumSize says:
    /**
     * Returns the minimum dimensions this border requires
     * in order to fully display the border and title.
     * @param c the component where this border will be drawn
     */
however this size is always one or 2 characters smaller than it needs to be so the remaining characters are getting cut off.

Expected: the border to show 'Test'
Actual: the border shows 'Tes'
