+ Using passthrough.vert and geometryrenderer.frag instead of the meshGeometryRenderer.vert and meshgeometryrenderer.frag
+ adding comments for the destroy function of GeometryTextureInfo and why to use it.
+ Change the depth buffer size changing part of Paint() function in datacontainerinspectorcanvas checking part.
+ Delete the commented codes which are not necessary.
+ Fix the opening braces and removing the redundant parts and only for debugging parts.
+ DVRVis and volumerendererdemo default file is revereted to the original locations.
+ Revert the shaders to the original ones.
+ StartMouseDrag and EndMouseDrag functions of the trackball are replaced with mousePress and mouseRelease.

- Delete the meshGeometryRenderer.vert and meshgeometryrenderer.frag.

+ Moving the geomteryshader vertex and fragment shader to application folder as they belong to it.
+ Removing unndeeded shader code.
+ Opening braces convention is considered for datacontainerinspectorcanvas.cpp and datacontainerinspectorcanvas.h  also.
+ Reusing textues for color and depth buffers instead of creating and deleting them.
+ adding gettrackball function to trackball event handler.
+ modifying resetcontent, mouse events in datacontainerinspectorcanvas class
+ using one depth buffer for datacontainerinspectorcanvas instead of one for every color buffer
+ using one frame buffer for whole datacontainerinspectorcanvas instead of one for every frame

Bugs:
- Invalid Enumerator during the rendering mesh
- Problems in deleting the generated color and depth textures.
- Depth darkening still has problem :(

+ update the get function of abstractproperty.h and abstractproperty.cpp to support the const objects.

- Still sufring from invalid enumerator in meshgeomtery rendering.

Resolved Conflicts:
	application/gui/datacontainerinspectorcanvas.cpp
	application/gui/datacontainerinspectorcanvas.h
	application/gui/datacontainerinspectorwidget.cpp
	application/gui/datacontainerinspectorwidget.h
	core/datastructures/imagerepresentationgl.cpp

+ Adding the functionality to rotate the rendered geomtery objects
+ Adding the functionality to set the rendered mesh by the user

- Still there are bugs with shader that I cannot set the color of the rendered mesh in the shader

# Adding functionality to render the mesh in the DataContainerInspectorCanvas and camera rotating around the object

# Fixing the bugs of the Color Window in the Canvas

# use 4 spaces instead of tab
# use QString operations instead of unsafe C String operations
# use static_cast casting instead of C casting

# Adding the color under the mouse cursor window and the color value in a line into the Data Inspector Widget.

# Take back the updateInfoWidget to its previous position and add a new updateColor function to just update the Color in the label.

# Add the ability to read the color when hovering the mouse into the canvas and dragging the right mouse button.

# Make a pointer from datacontainerinspectorwidget into datacontainerinspectorcanvas, as we need to call the updateInfoWidget() after updating the color.

# Make the updateInfoWidget() as public to be able to call it.

# Add the Capability to look up the color under the mouse button when one of the mouse buttons is pressed.

reverted changes from e7b11bfa: "added s_changed signal of properties also being propagated to its shared properties"
This was weak design and lead to problems with the AutoEvaluationPipeline.

Introducing usage of C++11 lambda functions instead of functors in some tbb::parallel_for blocks for better readibility

Merge branch 'log-highlighter-double-free-fix' of /mnt/bigone/git/repositories/berge/campvis into development

In its destructor, LogHighlighter first of all deleted its filter regex
explicitly, and then called `setFilterRegExp(0)`, triggering a second —
this time somewhat implicit — delete. If the filter regex pointer was
not NULL, this caused the application to crash due to a double-free.

Fix this error by not invoking `setFilterRegExp` in LogHighlighter's
destructor; the explicit delete performs the same cleanup as
`setFilterRegExp` anyways.

 * fixed 1D geometry TF editor
 * introduced OptionProperty to specify gradient computation mode
 * added s_changed signal of properties also being propagated to its shared properties
 * fixed sampling rate compensation when using adaptive sampling in simpleraycaster.frag

Fixed missing/wrong deregistration of GeometryXdTransferFcuntionEditors when their widgets are closed (and hence the GL contexts destroyed)

Merge branch 'revert-no-tree-vrp' of /mnt/bigone/git/repositories/sebastian.poelsterl/campvis into development

    This reverts commit 442d5051.

Fixes -Wignored-qualifiers

Added -fno-tree-vrp to CMake definition, since tree-vrp optimization breaks the code for some strange reason.

Fixes -Wsign-compare
