Fix pdflatex preview mode.

67. By Till Kamppeter on 2010-03-23

debian/patches/cups-raster-error-out-without-segfault-and-force-banding.dpatch:
Make the "cups" output device (CUPS Raster) error out correctly without
causing segfaults and also force banding mode as some PDFs do not render
otherwise (LP: #534525).

66. By Till Kamppeter on 2010-03-09

* debian/patches/pdftoraster-wait-for-ghostscript.dpatch: pdftoraster exited
  already before its Ghostscript subprocess finished. Thanks to Tim Waugh
  from Red Hat for the fix.
* debian/patches/cups-raster-fix-memory-reallocation.dpatch: Fixed bug
  in memory reallocation on bitmap size changes. Color depth was not
  taken into account. This caused black pages to be printed with some
  CUPS Raster drivers, like Turboprint. Fixes upstream bugs #691029 and
  #691108.
* debian/patches/fix-broken-korean-example.dpatch: Fixed example file for
  rendering Korean text.

no-cant-refill-scanner-input-buffer-error.dpatch: Ghostscript errored out
when getting fed with the Ubuntu test page
(/usr/share/system-config-printer/testpage-a4.ps) on stdin giving a
"Can't refill scanner input buffer" error. (Upstream bugs #691137,
#690909).

* New upstream release
   o libtiff-based tiff file output
   o New "tiffsep1" output device produces halftoned separations at 1 bit
     per pixel
   o Improved FreeType-based font rasterizing (not yet used as default)
   o Improved graphics library for vector graphics conversions
   o Many bug fixes on the PCL-XL printer drivers ("pxlmono", "pxlcolor")
   o Fixes on back side handling for duplex printing in the CUPS Raster
     output device ("cups").
* debian/patches/gs-cups-rgb-gamma.dpatch,
  debian/patches/cljet5-mediasize-fix.dpatch,
  debian/patches/pxl-driver-fixes.dpatch,
  debian/patches/gs-cups-fix-backside-on-duplex-jobs.dpatch: Removed patches
  backported from upstream.
* debian/patches/fix-build-of-executables.dpatch: Fix build of the "gs"
  executable, it was built as a shared library and not as an executable.
  This lead to an immediate segfault even before "main()" got called.
  Thanks to Robin Watts from Ghostscript for the quick fix.
* debian/control: Added build dependency on libtiff-dev.
* debian/ghostscript.links: s/8.70/8.71/
