## Detailed Description

Encapsulates OpenGL state modes and attributes.

Used to specific textures etc of osg::Drawable's which hold references to a single osg::StateSet. StateSet can be shared between Drawable's and is recommend if possible as it minimizes expensive state changes in the graphics pipeline.
