Tags: 2.9.11-1
http://bugs.debian.org/592420
* Removed bug-555869-ftbfs_with_binutils_gold.dpatch since upstream has
  already taken care of the issue.
* Removed bug-528229.dpatch since the pkgconfig files are now also split
  in upstream.
* Removed explicit dependency on GLU.
* Upstream no longer includes osgIntrospection (Closes: #592420).
* Disabled zip plugin as its implementation stores an embedded copy of
  zlib.
* Enabled Qt support. Thanks James Goppert.
* Enabled SVG and PDF plugins. Thanks James Goppert.
