Detailed Description

This class inherits from osg::Drawable, which allows us to hook into our indirect engine to render using indirect rendering.

In the case of features, the DtIndirectGeometry is parented to the feature tile nodes and manages the indirect rendering of all the feature points in that tile For paging databases it manages the indirect rendering of a complete tile For terrain patches it manages the indirect rendering of the full patch
