* Update to 8.71.[1]  Changes include:

 - Support for tiff file output is now provided using the libtiff
   implementation rather than our more limited native code as in
   previous releases. There is also a new 'tiffsep1' output
   device which produces halftoned separations at 1
   bit-per-pixel, in contrast to the 'tiffsep' device which
   produces 8 bit-per-pixel plates.

 - The graphics library has been updated to provide more accurate
   scan conversion of vector art including fixes to dash
   behavior, transparent stroked paths, thick stroked paths,
   radial shadings, xps cap handling, "pie" joins, degenerate
   beziers, improved handling of dropouts in thin strokes and
   better thin axis-aligned strokes.

* Fix cairo support.  GS_cairo is added to the drivers list (this
  is disabled by default).  When WITH_CAIRO is defined, GS_cairo
  will be set by default.[2]
