* Support read-out of texel values also for 3D images
* introducing tgt::Texture::texelAsFloat() for 3D images
* Fixed Qt crashes in FloatPropertyWidget caused by changing GUI from non-GUI thread

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!

* Introducing MultiIndexedGeometry data type
* Introducing GeometryDataFactory::createTeapot()

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()

* Moving to Apache 2.0 license
* Updated AUTHORS.txt

+ 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.

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.

+ 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.

+ 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.

Fixes -Wswitch

Even though all integer-based properties derived from NumericProperty
used the same step value, T(1), it had to be specified when
instantiating them. To reduce boilerplate code in property
constructors, NumericProperty now uses T(1) as the default step value.

Revised event handling system: Got rid of campvis::AbstractEventHandler and replaced with functionality of tgt::EventListener and tgt::EventHandler

A new attribute has been added to all numeric properties: step value. It
determines the value of a single increment/decrement that numeric
property widgets use when their associated properties are modified using
sliders or spin boxes (users are still able to type any valid property
value in text edits).

Numerous processors and pipelines had to be updated to work with the
changed NumericProperty interface. However, choosing a well-suited step
value for each property can make it easier for users to modify the
property — using one step value for all properties leads to cases where
it is either too small, causing users to go through property values
which don't cause any visible change, or too big, making it difficult to
quickly determine the right property value.

QtThreadedCanvas used to ignore all repaint events send to it by Qt in
order to avoid problems with threading. As a result, however, it would
become blank when docked/undocked, and display garbage in those of its
regions that some other widgets have moved over.

To fix this, the API of TGT's Painter class had to be slightly modified
and now mirrors that of Canvas with regard to painting-related
operations. The paint method has been made protected; it's supposed to
implement the painting logic and shouldn't be called directly. A public
repaint method has been introduced to let canvases notify their
associated painters that they need to be redrawn. The default
implementation simply calls paint() immediately; threaded painters,
however, override it to schedule render jobs that run in separate
threads.

All existing threaded painters have been updated to reduce the
visibility of their paint methods and provide public repaint functions.
Consequently, QtThreadedCanvas can now properly handle repaint events by
delegating to its associated painter's repaint method.

* fixed (de)initialization of DataContainerInspectorWidget and its canvas

* added slice marker rendering to SliceExtractor

 * Moved destruction of ReferenceCounted object to seperate thread (thus unloading rendering thread)
 * integration of OpenGL garbage collector into OpenGLJobProcessor (finally, you don't need to care anymore whether your code might call a GL object destructor and hence needs an OpenGL context)
 * changed DataContainer implementation from mutex/lock to concurrent container
 * fixing improper order of GL object deinitilization on program exit
