All classes in campvis-application now have the CAMPVIS_APPLICATION_API macro specifying dll export/import state. The executable is now called campvis-gui.

Renamed CampvisPainter to PipelinePainter. The PipelinePainter now directly belongs to the corresponding AbstractPipeline, which also owns the pointer and takes care of creating, (de-)initializing and destroying it.

* Added stretch widget to PropertyCollectionWidget

Label is now hidden by default for Button Properties which saves space
for long button descriptions

* Remove explicit use of Qt::QueuedConnection. As it turns out, when the
  event is emitted by a thread, different from the GUI thread, it is
  automatically enqueued.
* use #ifdef instead of #if

in the property window.
As this causes the property widget to move each time the user clicks on a
processor.

When rapidly switching between processors in the tree view, the
PropertyCollectionWidgets would sometimes cause the program to crash. This
happened because some signals originated from a different Thread and
sometimes caused a user-after-free error on the widget objects.

* Workflow stages now store the visibility of pipeline canvases
* Extended PipelineFactory to also hold creator functions to create workflows
* CampVisApplication now creates and initializes workflows when launched with "-w WorkflowName" parameter

refs #13

* Improved appearance of PipelineTreeWidget
* Fixed IntPropertyWidget and FloatPropertyWidget recursively setting the widgets value, when the change event comes from the widget itself

phew! transfer function docking fixed. crashed once for some reason, couldn't recreate the condition

Fixes: saving color for simpletransferfunc, geometry1d..:addKeyPoint() added, ..editor::mousePressEvent updated, transfer..lua update to save all point and colors

* Removed CameraProperty, CameraPropertyWidget and TrackballNavigationEventListener
* replaces all known occurrences of the above three with the new TrackballCameraProvider processor
* introduced TrackballCameraProvider::reinitializeCamera()

Moved AbstractJob and OpenGLJobProcessor from campvis-core to tgt and adapted and cleaned up all necessary includes/references.

The new OpenGL wrapping API allows for full multi-threaded access to OpenGL contexts. Instead of one single thread scheduling all OpenGL jobs for all contexts, the new GlContextManager allows for OpenGL access from multiple threads while ensuring that each OpenGL context is acquired by only one thread at a time.

Detailed list of changes:
* tgt::GlContextManager keeping track of which threads acquire which OpenGL contexts and which threads currently have a context acquired.
* OpenGLJobProcessor does no longer schedules and execute the OpenGL calls for all existing contexts, but only for one single context that can be used for background tasks or other jobs that explicitly need a valid OpenGL context.
* AbstractPipeline now implements the Runnable interface and thus runs in it's own thread. This thread also owns the pipeline's OpenGL context.
* AbstractPipeline has a new pure virtual method executePipeline() that has to perform all computations done by the pipeline.
* AbstractPipeline now takes directly care of calling Painter::paint() of the pipeline's canvas (instead of signalling the Painter). However, the Painter interface needs further cleanup.
* AutoEvaluationPipeline was adapted to the new AbstractPipeline API, hence executing processors is no longer delegated to the OpenGLJobProcessor or the SimpleJobProcessor but entirely done in AutoEvaluationPipeline::executePipeline() and thus in the pipeline's thread.
* Adjusted CampVisApplication, DataContainerInspectorWidget, and GeometryTransferFunctionEditor to the new API.

* AbstractPipeline offers getter for the canvas to execute jobs in the pipeline's OpenGL context
* PropertyCollectionWidget adds a spacer element at the end to prevent element stretching when there is too much free space
* job.h offers new CallFunctionObjectJob to create jobs on the fly using lambda functions (the respective makeJob and makeJobOnHeap are inlined to prevent linker errors)

[merged commit]clean ups, fixes for g++ errors and warnings, and edits for cppcheck errors (except for the 480+ in the external library AlgLib)

Replaced DataContainer::s_dataAdded<const std::string&, DataHandle> with DataContainer::s_dataAdded<std::string, DataHandle>.

relocated mscopysegmentation module

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

save results into csv
akima spline interpolation using alglib, deleting nearest point

alglib library. extensive trimming required

ctrl+wheel zooming, arrow movement, ctrl+z, atl+click_nearest+click to edit _nearest point

multi object, multi location, multi slide contour point/line painting

draft code for addobject deleteobject

added ContourObject class linked with add and delete button.

added a proxy class of Vec4Property/Widget as colorproperty/widget to control drawing color

Conflicts:
	modules/vis/processors/sliceextractor.cpp

edited DevilImageReader to read multiple files having same name pattern: somePrefix_[number].[extension] given the 1st file name

Worked on DevilImageReader to load single 2d image for 3d rendering

exp_01 commit

* Slight changes to the API: renamed signal::trigger() to signal::triggerSignal() and signal::queue() to signal::queueSignal()
* Replaced all sigslot signal emits through operator() with emits through emitSignal() to enable debug feature.
* Fixed a possible race condition when deleting a GeometryTransferFunction and its editor window at the same time (as this will happen from different threads).

refs #384

Removed all occasions where references to DataHandles were used, since especially their use in signals may lead to segfaults or other undesired behavior.

Introducing sigslot::concurrent_pointer_list<T> a list-like container allowing thread-safe bidirectional iteration, insertion and removal of elements. Single constraint is that the element type must be a pointer type (or at least have pointer semantics) and never be 0. This is neat, as this class offers exactly what we need for a lock-free sigslot implementation.

Updated sigslot implementation to use concurrent_pointer_list for connection storage. Hence, we can get rid of the locking mechanisms, which got completely removed.

Since this simplified template definitions for sigslot, many campvis files needed to be adapted (i.e. removing the <> from has_slots<> and signal0<>).

Depending on StringProperty's display type, its property widget shows either just the QLineEdit, or additionally a browse button that pops up a QFileDialog for either loading or saving a file, or choosing a directory.

closes #43

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