OpenSceneGraph/include/osg/Uniform
Robert Osfield c0b04cc37b Introduced new osg::UniformBase class to enable an extensible uniform class hierachy 
Added osg::UniformTemplate, osg::UniformArrayTemplate and a set of IntUniform, IntArrayUniform etc. to make it easier to interact with basic types more efficiently.
