CID 11447: Unchecked dynamic_cast (FORWARD_NULL)
Dynamic cast to pointer "dynamic_cast <struct osg::NodeCallback *>(nc->clone(this))" can return null.
Assigning null: "first" = "dynamic_cast <struct osg::NodeCallback *>(nc->clone(this))".
The clone() implementation is written using macro's so that it always returns the type of Object
being cloned so it's normally safe to assume that a dynamic_cast<> will always return a valid pointer as long
as the new T that involves creates a valid object. However, if the class being cloned doesn't correctly
implement the clone() method then their potential for the dynamic_cast to fail and will return a NULL and will
result in a memory leak of the object of paraent class that the clone would have defaulted to.
I've tightened up the CopyOp.cpp code to check the return type and added better handling of the clone in the
osg::clone() methods so thay don't have any potential mememory leaks and report warnings to OSG_WARN when
problems are encountered. It may be more apporpriate to throw an exception so will need to ponder this
issue further.

After this line, the value of "needspace" is equal to 0.
Assigning: "needspace" = "false".
Technically the report is correct, but the code is just debugging code that was there just in case
the code needed to be reviewed. This code is long since through it's debugging stage so the code
is no longer really worth keeping so I've removed it for cleanness sake.
ID 11667: Uninitialized scalar field (UNINIT_CTOR)
Non-static class member _useVertexAttribAlias is not initialized in this constructor nor in any functions that it calls.
Member variable should have been initialized but this varaible will have always been initialized in later code
before it was used anyway so wouldn't have resulted in a runtime bug.
CID 11414: Logically dead code (DEADCODE)
After this line, the value of "vboMemory" is equal to 0.
Assigning: "vboMemory" = "NULL".
Another case of debugging code paths being picked out. I have chosen to just delete these paths as the code
looks to be working fine and less code is better than more code when it comes to maintenance.
but I've moved this initialization into the constructor to make the code more managable.

Following are both false positives as the the scope they are in will always assign the object to a ref counted
structure. I've modified the code to use ref_ptr<> to just make it clear that it's underscope, although
this is not strictly neccessary as the code is OK, I introduced this for clarity and robustness in
presence of exceptions.

Report highlighted the fact that later code wasn't using the indices variable when it should have been, so
potentially a higher impact that the severity suggested by Coverity.

The pvr format which can be used as a wrapper for different compressed and uncompressed formats supports this compression algorithm. The original pvr compression uses the pvrtc format. The handling of pvrtc is already implemented in the pvr plugin. PVR provides wrapper functionality for some formats, e.g. etc or even dxt/dds.
Our target system (gles2) is able to use the etc compression format. With minor changes in the submitted files, there is no need to write a separate plugin. However the original pvr texture compression formats are not supported on our target, which is the reason for this extension.
The changes mainly consist in the definition on new enum values in the classes and headers of ReaderWriterPVR,Image and Texture. I also found some locations where the handling of the original pvr textures was not implemented. These are also part of this submission."
I also fixed the vsync implementation introduced with rev.11357 that was crashing with the Windows Error #170. So I removed your temporary /* */ around the vsync condition..."
That is, it calls ::wglCreateContext to create a context, not the member method createContextImplementation(), which takes into an account the Traits.
In my situation, this prevents a GL 3.x context from being created.

2nd - Script to use a 3rd party directory with basic libraries: libjpeg,libpng,libtiff,giflib,freetype,curl,gdal.
3rd - Change in the GLES library loading for Android. That should make GLES2 work properly.
4rth- Included two defines RGB8_OES and RGBA8_OES as a substitute in GLES for RGB8 and RGBA8
5th - OpenGL and GLSL version identification changed to recognize GLES versions properly

The main motivation for this is to easily allow the user to specifiy that the device is in a horizontal orientation rather then having to rotate the view matrix. All flags have been tested individually as well as in combinations. The default is ALL_ORIENTATIONS to keep the exiting functionality for anyone who hasn't specified WindowData for their context traits.
