b90503fdf5 Introduced new shader composition approach that utilizes #pragma requires(), #pragma import_defines() and #ifdef in GLSL to enable multiple different versions of shaders based 
on defines passed in from osg::StateSet::setDefine(..).

a331680cec From Aurélien Chatelain, "the smoothing visitor did not handle shared arrays. It may leads to bad geometry arrays when a shared array is involved in the scene. 
This submission adds shared array duplication (and moves the SharedArrayOptimizer declaration in MeshOptimizer to make it callable from the SmoothingVisitor)."

Submitted by Marc Helbling.
Edited by Robet Osfield to retain the usual OSG coding style.

58c47e9842 From Marc Helbling, "please find enclosed a submission that should improve the VertexAccessOrderVisitor (pre-transform) optimizer: 
* it sorts primitives to keep "more complex" primitives first; maybe you'll prefer to have this as an option (but usually it should make more sense to pre-transform triangles before e.g. lines)
* currently, the visitor rely on TriangleIndexFunctor and does not take care of points and lines (see https://github.com/openscenegraph/osg/blob/master/include/osg/TriangleIndexFunctor#L124-130). This can lead to issues e.g. if you store the wireframe lines along with some triangles: the triangles will be reindexed but not the line. I've therefore added osg/include/TriangleLinePointIndexFunctor to index triangles, lines and points and derived VertexReorder from this class.
* to avoid issues, shared arrays are duplicated. However, in some cases (e.g. an UV channel shared in the geometry only) this is not required. I'm adding a SharedArrayOptimizer to optimize this: it looks for duplicated UVs before the array duplication and deduplicate arrays after.
"

117869d154 From Marc Helbling, "please find the mergeTriangleStrip code merged in osgUtil::TriStripVisitor. 
I've removed the references to DrawArrays as we should no longer produce any.

Note that:
* as the name suggest, it only works for triangle strips but could probably be easily extended to quads
* the resulting primitive is not highly optimized; we could probably sort the strips in order to minimize the number of primitive restart
* as we may merge DrawElementsUInt and DrawElementUShort, the code will only generate DrawElementsUInt"
