  \brief Get the height of a font, including its line spacing.

  This is required to vertically center the symbol to the text line
  in the Nfc Info view. The text can have a height of multiple lines,
  nevertheless, the icon needs to be centered to the first line and
  not the multiline text.

  Specially important to adapt to the font height changes between
  MeeGo Harmattan PR 1.1 and PR 1.2 (line spacing increased in PR 1.2,
  to increase text legibility).
