v0.3.4

0.3.4 (2021-12-11)

• Dropped support for GHC 7.10.

• Added xftDrawStringFallback, which works like xftDrawString but
  supports font fallback.

• Added xftTextAccumExtents, which works like xftTextExtents but
  possibly uses different fonts for different parts of the string and
  returns the accumulative extents.

• Added the functions xftfont_max_ascent, xftfont_max_descent, and
  xftfont_max_height to gain information about a non-empty list of
  XftFonts.
