Detailed Description

The renderer handles drawing the opengl scene.

It is used by a GLViewer, which is a wxWidget. The work of generating textures to represent the image is done by a TextureManager, and the remappings are made in display lists by a MeshManager. The GLViewer gives us instances of those objects to use.
