If you need one of these two C++11 headers, include <ext/threading.h> instead, which will use C++11 headers if present or TBB's compatibility layer otherwise.

closes #567

This was due to a missing/wrong GL_PACK_ALIGNMENT setting.

closes #568

INVALID_RESULT, INVALID_PROPERTIES, INVALID_SHADER is validated automatically by AbstractProcessor::process(). Hence, there is finally no need anymore to validate these three different levels in each processor.

Openigtlink support

openigtlink processor implementation and matrix processor.
changes to mprrenderer and mprdemo are not relevant (should be in another branch)

Fixed various GCC and Cppcheck warnings.

Moved RegistrationDemo and SegmentationDemo pipelines from VIS to ITK module to avoid linking errors if ITK module is disabled. Furthermore, renamed classes to ItkRegistrationDemo and ItkSegmentationDemo.

Itk Segmentation and Registration: wrappers and demos

This branch makes use of the ItkReader and currently contains a SegmentationDemo and a RegistrationDemo that use Itk wrappers for segmentation and registration algorithms. It is meant to be a starting point for future Itk segmentation and registration algorithms that are to be wrapped. Commits have been cherry-picked from the mhaimagereader branch.

Set the default background color to black such that the volume visualization can ignore the background

Use ItkReader instead of GenericImageReader. Currently, this is more suitable for the SegmentationDemo and RegistrationDemo because of the supported image formats

inherit a VolumeExplorer instead of an AbstractProcessor - avoids duplications in the required implementation + get dot scribbler coordinates for the segmentation seed

registration demo - starter: so far, rigid registration for 3D with Mattes Mutual Information metric - Cristina Precup

Qt threading issues

Lua console

Finished a quick and dirty implementation of a Lua console in CampvisApplication.

* CMake build files now support unix builds
* SWIG interface files and Lua wrappers are now fully C++ compliant to comfort GCC
* Hacked shared/static builds of the campvis-modules module even more, but now it works on both MSVC and GCC

* AbstractData now stores a weak_ptr to its shared_ptr owning group if existant. This avoids unintentional creation of multiple owning groups where each eventually tries to delete the AbstractData on its own (which will certainly not work)
* Updated DataContainer implementation to use a hash map instead of an unordered map.

Enforced update of min/max/singleStep values in AbstractAdjusterWidget to be performed in Qt main thread through additional indirection via Qt queued signals.

Refactor reference counting

* Introduced two new tgt::LogManager log levels LuaInfo and LuaError.
* ScriptingWidget registers itself as logger and prints the Lua output into the console window.

* Added OrCombinedPointPredicate implementation
* Updated default settings in PredicateDemoCarotid2 pipeline

* parser now allows whitespace in formula
* exports _camera matrix (if present) to m_cameraProperty in parserMode
