Removed unused variables
Restored the rescaleToZeroToOneRange() to address rendering issues.
Moved Handled propety from GUIEventAdapter to Event base class.

Added CameraManipulator::finishAnimation() method to allow application code to stop any animation/throw of manipulators.
Added BoundingBox::contains(const vec_type& v, value_type epsilon) method with new epsilon parameter to make it easier to test for containment in the presence of numerical errors
Added panning and zooming functionality to transfer function UI prototype code.
From Stephan Huber, * GUIEventAdapter: add support for getting normalized touch points
* MultiTouchTrackball: some code cleanup and support for normalized touch-points
* oscdevice: receiving and sending multi-touch-events via the Cursor2D-profile from TUIO
* added some documentation
From Stephan Huber, compile fix for OpenGL ES on iOS.
From Stephan Huber, "minor ios-fixes/-enhancements

* force _OPENTHREADS_ATOMIC_USE_BSD_ATOMIC for IOS device + simulator as the test does not pick the right implementation
* fixed a small compile-bug for iphone-example
* added a check to prevent multiple realization of a GraphicsWindowIOS-object

Added Geometry::drawVertexArraysomplemetation(..) and drawPrimitivesImplemenation(..) methods that are called from drawImplementation(..).  These new vertex methods 
allow subclasses from osg::Geometry to specialize the vertex array setup or how the primitives are dispatched to OpenGL.
Converted std::max to osg::maximum to fix VS2013 build error
From Farshid Lashkari, "I recently encountered an issue attempting to load an IVE file generated by an older version of OSG. The file contained dxt1 compressed image data with mipmaps. The loaded model would cause crashes when passing the mipmap data to glCompressedTexImage2D. It seems that the size of the data array within the IVE file did not match the computed size from Image::getTotalSizeInBytesIncludingMipmaps(). This essentially made the mipmap offsets invalid within the Image object.

I'm not sure if the IVE was simply generated incorrectly, or if the Image::getTotalSizeInBytesIncludingMipmaps() was modified since the file was generated. Either way, I added a simple check in the IVE loader so that it clears the mipmap offsets if the actual data size does not match the computed data size. This seems like a safe fallback since the mipmap data can be automatically generated, and it fixes the problem in my case.

Also, while looking into this issue, I noticed that the osgDB::InputStream class applies the serialized image allocation mode. However, since the serializer is allocating the image data itself, it seems like it should force the allocation mode to USE_NEW_DELETE.

From Stephan Huber, "CLang / LLVM on OS X seems to have a problem compiling the osgGA-serializer. (It was reported before on the list, but the error is hard to track as it shows up only sometimes)

I fixed the compile-error with a dedicated destructor of osgGA::GUIEventHandler"
Added new osgVolume::VolumeScene and osgVolume::MultipassTechnique class shells that will be filled out to provide multi-pass volume rendering that handles mixing of
3D meshes with volume rendering and segmentation of volumes via a user defined hull mesh.
Removed trailing spaces, added missing return to last lines
From Kristofer Tingdahl, Build fix for svg plugin that makes sure the version of librsvg is at sufficient, and fixed a missing virtual destructor warning.
Warning fixes
Added initial render to texture functionality into osgVolume::VolumeScene
Replaced readShaderFile() usage to readRefShaderFile()
Added support for using shaders to render the RTT textures with depth
