## Detailed Description

Pure virtual base class for drawable Geometry.

Contains no drawing primitives directly, these are provided by subclasses such as osg::Geometry. State attributes for a Drawable are maintained in StateSet which the Drawable maintains a referenced counted pointer to. Both Drawable's and StateSet's can be shared for optimal memory usage and graphics performance.
