< BLOCKQUOTE > osgGL2::ProgramObject is an application-level abstraction of the OpenGL Shading Language glProgramObject.
It is an osg::StateAttribute that, when applied, will install an OGLSL
shader program for subsequent rendering.
osgGL2::ShaderObjects containing the actual shader source code are
attached to the ProgramObject, which will then manage the compilation,
linking, and installation of the GL shader program.
ProgramObject will automatically manage per-context instancing of the
internal objects, if that is necessary for a particular display
configuration.< / BLOCKQUOTE >
