   * <li>TrueType (*.ttf);</li>

   * <li>TrueType Collections (*.ttc);</li>

   * <p>Some formats may contain more than a single font, for example

   * *.ttc and *.dfont files. This is the reason why this function

   * returns an array.

   *

   * <p>The implementation reads data from the buffer only when

   * needed. Therefore, it greatly increases efficiency if

   * <code>buf</code> has been obtained through mapping a file into

   * the virtual address space.

   *

   * @throws FontFormatException if the font data is not in one of the

   * known formats.
