Encapsulate OpenGL glStencilFunc/Op/Mask functions.
All functionality except INCR_WRAP and DECR_WRAP is supported by OpenGL 1.1. INCR_WRAP an DECR_WRAP are available since OpenGL 1.4 or when GL_EXT_stencil_wrap extension is present.
If INCR_WRAP or DECR_WRAP values are used while they are detected to be not supported, the INCR or DECR values are sent to OpenGL instead. Note: do not use Stencil::getFunction() to detect whether WRAP operations is used as the object's value is kept intact. Use osg::Stencil::getExtensions() method instead.
OpenGL 2.0 introduced two side stenciling that is available through osg::StencilTwoSided class.
