bool getFastPathHint() const { return _fastPathHint; }
/** Return true if OpenGL fast paths will be used with drawing this Geometry.
* Fast paths use vertex arrays, and glDrawArrays/glDrawElements. Slow paths
* use glBegin()/glVertex.../glEnd(). Use of per primitive bindings or per vertex indexed
* arrays will drop the rendering path off the fast path.
* Fast paths directly use vertex arrays, and glDrawArrays/glDrawElements so have low CPU overhead.
* With Slow paths the osg::Geometry::drawImplementation has to dynamically assemble OpenGL
* compatible vertex arrays from the osg::Geometry arrays data and then dispatch these to OpenGL,
* so have higher CPU overhead than the Fast paths.
* Use of per primitive bindings or per vertex indexed arrays will drop the rendering path off the fast path.
