Added cube and hull rendering support
Fixed handling of volume tiles with a region.
Improved the setting of sample density/ratio so that they are consistent
Fixed iso surface shaders
From Paul Martz, "We discussed the issue of GL_RED_SNORM and GL_RG_SNORM some time ago, but the issue was never completely resolved. Please see the attached submission to fix the issue.

osg/GL2Extensions was incorrectly defining GL_RED_SNORM and GL_RG_SNORM as part of the definitions for OpenGL v3.1. However, a quick review of the 3.1 spec indicates that these are not part of the 3.1 standard.

My attached change moves these definitions out of the #ifndef GL_VERSION_3_1 conditional block, and defines them conditionally if not already defined. This allows the DDS plugin to build for GL3.

From Bjorn Hein, "please find attached a small fix for RayIntersector.cpp.

* Changes are made against trunk
* Reason: crashes when using specific constructor from RayIntersector
* Info: Line 42:  added in constructor
RayIntersector::RayIntersector(const Vec3d& start, const Vec3d&
direction) missing initialisation of _parent

From Bjorn Blessing, "I got bored of the constant reports of “missing chunk 0xA08A” when reading 3ds-files. After a bit of research I discovered that this property is related to the advanced transparency settings for the material in 3D studio. In this case the falloff parameter. These controls affect the opacity falloff of a transparent material. And the property chooses whether falloff is in or out. I have added the property to the file reader BUT no changes are made to make this property propagate into the osgMaterial. But at least we get rid of this annoying error message."
From Marcel Pursche, "The problem is that when OpenThreads is build with the Linux pthreads implementation all threads inherit the processor affinity from their parent thread.
This behavior is also described in the pthreads man page (http://man7.org/linux/man-pages/man3/pthread_create.3.html):

>
> Linux-specific details
> The new thread inherits copies of the calling thread's capability
> sets (see capabilities(7)) and CPU affinity mask (see
> sched_setaffinity(2)).

To prevent this behaviour I wrote a patch that explicitly sets the affinity mask to all cores of the system, if no specific affinity was defined with PThread::setProcessorAffinity(unsigned int) .

Thank you!

From Jan Peciva, "I am sending four fixes to obj plugin:

- materialName used to be not stripped of whitespace, making number of models
fail to load materials; now fixed
- stripping was considering spaces only, thus models using tabs had problems
to load correctly; fixed
- fixed references to textures; they did not performed conversion to native
directory separators
- make d (dissolve) takes precedence over Tr (transparency); there seems to be
a confusion about the Tr item - some claiming 1 to be opaque and 0
transparent, while number of models uses exactly the opposite. d (dissolve),
if present in the model, does not suffer from this confusion, thus using it
instead fixes the problem for many many models.

I put many comments to the file concerning d and Tr item as others may further
investigate. Let me know in the case of any problems."
Fixed build when using of double BoundingBox/BoundingSphere
From Pjotr Svetachov, previous obj "commit broke compilation under visual studio 2013. To use std::not1 you need to include the functional header. Here is a fix."
From Pjotr Svetachov, "We had a small problem converting skeleton animations from fbx to osgt
format. Turned out that the serializer didn't handle bone names with
spaces very well (the 3ds studio max biped for instance has spaces by
default). Here is a small fix for the problem."
From Sebastian Messerschmidt, "n the trunk version the osgGA::GUIActionAdapter has additional functions for lineIntersection which use osgGA::GUIEventAdapter&, but the class declaration is neither forwarded, nor is the header included.
Using the trunk together with osgEarth 2.5 will fail to build, due to the missing type.

Attached is the file forward declaring osgGA::GUIEventAdapter."
From Remo Eichenberger, "I have extended the TIFF plugin that allows you to write LZW or JPEG compressed TIFF's. Options are:

tiff_compression = lzw | jpeg"
Updated ChangeLog and fixed Contributors list
Added extra search paths to add compatibility with Kubuntu/Ubuntu 14.04 now locaton for freetype
Disabled warnings to address issues in FBX headers that generate lots of warnings that we can't fix.
From Paul Cheyrou-Lagreze, "Attached is fix/feature for FBX osgplugins against latest trunk:

- ReaderWriterFBX.cpp: add "z up scene axis" support:  FBX provides facility to convert model scene axis during conversion. Currently fbx plugin convert axis to fbx:opengl axis system (which is arbitrarily at Y up, as opengl is in reality axis agnostic) and sometimes what is needed is Z up so added an option for Z up conversion

- FindFBX.cmake: add support for latest fbx sdk ( 2014.2 )"
Renamed FindFreeType.cmake to FindFreetype.cmake to enable CMake build to pick up on CMake's own FindFreetype.cmake when it's available.
Fixed comment
