485709f708 Moved GL2Extensions functionality into the include/osg/GLExtensions header and new GLExtensions object. 
Moved the #defines into new include/osg/GLDefines
Converted all GL2Extensions usage to GLExtensions usage

22eae68e48 From Mathias Froehlich, "This is a generic optimization that does not depend on any cpu or instruction 
set.

The optimization is based on the observation that matrix matrix multiplication
with a dense matrix 4x4 is 4^3 Operations whereas multiplication with a
transform, or scale matrix is only 4^2 operations. Which is a gain of a
*FACTOR*4* for these special cases.
The change implements these special cases, provides a unit test for these
implementation and converts uses of the expensiver dense matrix matrix
routine with the specialized versions.

Depending on the transform nodes in the scenegraph this change gives a
noticable improovement.
For example the osgforest code using the MatrixTransform is about 20% slower
than the same codepath using the PositionAttitudeTransform instead of the
MatrixTransform with this patch applied.

If I remember right, the sse type optimizations did *not* provide a factor 4
improovement. Also these changes are totally independent of any cpu or
instruction set architecture. So I would prefer to have this current kind of
change instead of some hand coded and cpu dependent assembly stuff. If we
need that hand tuned stuff, these can go on top of this changes which must
provide than hand optimized additional variants for the specialized versions
to give a even better result in the end.

An other change included here is a change to rotation matrix from quaterion
code. There is a sqrt call which couold be optimized away. Since we divide in
effect by sqrt(length)*sqrt(length) which is just length ...

228fd04a19 Removed the exclusion of CullSettings from the genwrapper.conf, and then changed the CullStack RefMatrix& methods to RefMatrix* 
as the RefMatrix& versions caused the wrappers to fail.

e928bca4c9 Changed the Viewer::realize() calls across to not using the threading paramter 
leaving it up to the Viewer to specify the mode (which by default is MultiThreaded).

disabled in this case.
