Replaced all occurrences of GL_POLYGON render mode with GL_TRIANGLE_FAN since GL_POLYGON is deprecated.

* Fixed DataSeriesSplitter::updateProperties()
* Fixed VolumeExplorer's camera ID not being dependent on output image name
* Added early return to AbstractProcessor::invalidate(level) if level == 0

Further work on refactoring the camera API. Added proof-of-concept implementation into VolumeRenderer and VolumeExplorer:

* Replaced two assertions in PointPredicateHistogramProperty with ifs and LERRORs.
* Minor adjustments in IvusTcDemo.

The VolumeExplorer has now an additional property defining which view is shown in the big section (and which in the three small sections). Hence, now it is also possible to show one of the slice views in large and have the volume rendering in small.

To better support sharing the functionality of slice rendering, the SliceExtractor processor was refactored: Similar to the RaycastingProcessor, the main functionality was moved to an abstract base class, the SliceRenderProcessor. This takes care of computing all the necessary transformation matrices, optionally rendering crosshair and integrating geometry, as well as handling user input to support scribbling. The actual SliceExtractor processor now only implements the rendering of the slice itself, i.e. applying the transfer function.

In this regard, VolumeExplorer was updated to use the generic SliceRenderProcessor, and TransFuncWindowingEventListener supports changing of its assigned property.

relocated mscopysegmentation module

relocated alglib library. Compiler warning level raised to w1 to get rid of float-double conversions.

Removed unlockInExtraThread flag from AbstractProcessor::process() - this is no longer needed as signal handling is done asynchroneously now anyway.

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.

* Geometry1DTransferFunctionEditor not correctly drawing image intensity histogram.
* VolumeExplorer not always initializing slice- and raycasting render size properties.

To now, each property hat an _invalidationLevel field that was evaluated by processors when the property had changed in order to determine what has to be done. However, since properties could also be owned by other classes, this design was semantically misleading.
Therefore, it was removed with this commit and replaced by the invalidation map of each processor. Now, this per-processor mapping of property -> invalidation level is managed by the processor itself. Furthermore, the invalidation level is no longer setup during property creation but during AbstractProcessor::addProperty(), which also makes much more sense.

ATTENTION: Due to these intrusive API changes, the code of all processors and other classes handling properties needs to be changed. As a reminder, the implementation of addProperty() also now takes a reference instead of a pointer, so that old code does no longer compile.

refs #542

* Introducing SliceExtractor::onEvent() to handle mouse events and generate point scribbles from it, which are then published using the s_scribblePainted signal
* Implemented SliceExtractor being able to render geometry in the slice space (with correct clipping)
* Implemented creating and handling of scribbles in VolumeExplorer in cooperation with the SliceExtractor. Therefore, mouse events are passed to the SliceExtractor, the VolumeExplorer takes care of assembling the scribbles into proper geometry, which is finally rendered by the SliceExtractor. The scribbling can be optionally turned on using the VolumeExplorer::p_enableSclibbling property.

* Fixed bug introduced in 8a8f9bba: Mouse wheel handler was modifying wrong slices
* Updated README.md

* Fixed orientation of XY-slice (flipped along Y axis)
* Implemented background for raycasting result
* Fixed sum for volume rendering integral evaluation in simpleraycaster.frag

* RaycastingProcessor now has the p_targetImageID property and optionally uses a custom GLSL version for the shader
* Introducing PropertyCollection::getNestedProperty allowing to get nested properties with a single method call
* Fixed StringUtils::split() methods being broken with multi-character delimiters

C++ implicit conversion rules made ShaderManager::loadSeparate() ambiguous in some cases. So I decided to cut loose ends and completely refactored loading with standard version into ShaderManager::load() and loading with custom version into ShaderManager::loadWithCustomGlslVersion().
ShaderManager::loadSeparate() is no longer available!

* Fixed VolumeExplorer not always correctly invalidating sub-processors
* Updated ProxyGeometryGenerator to new Processor design (using INVALID_PROPERTIES invalidation level)

Refactoring AbstractProcessor::process() for clearer semantics and better and more uniform handling of invalidation levels:
 * AbstractProcessor::process() now calls updateShader(), updateProperties() and/or updateResult() with respect to the current invalidation level
 * each processor shall no longer override process() but the updateXYZ() methods, at minimum updateResult()
 * AbstractProcessor::process() takes care of (un)locking the processor itself (no need to do this from the outside anymore)

Further implicit changes:
 * Removed redundant HasPropertyCollection::updateProperties()

Completely moved the image data handle and histogram computation from the TF to the TF property. Histogram computation is now thread safe.

* fixed VolumeExplorer/VolumeRenderer not correctly updating the proxy geometry due to missing locks and thus skipped invalidations
* adjusted VolumeExplorerDemo image URL

* Moving to Apache 2.0 license
* Updated AUTHORS.txt

Cleaned up and slightly revised GeometryData API. Cleared the way for non-value semantics. Introducing GeometryDataFactory, a collection of static methods to create standard geometric primitives.

Fixes -Wsign-compare

fixed VolumeExplorer::updateProperties()

Refactored DataNameProperty: Got rid of issueWrite() and connect(). Automatic invalidation of connected (shared) DataNameProperties is now delegated to AutoEvaluationPipeline.
ATTENTION: needs TBB 4.2 (not yet in repository, will be changed later)

introducing AbstractProcessor::updateProperties(DataContainer&) which is automatically called by AbstractPipeline when a processor invalidates its INVALID_PROPERTIES flag

Further work on Issue #141: Introducing TrackballNavigationEventListener::reinitializeCamera() with tgt::Bounds or the new IHasWorldBounds interface as argument

work in Issue #141: Implemented listening to viewport size property in TrackballNavigationEventListener and thus removed obsolete TrackballNavigationEventListener::SetViewportSize().
