Convert from Vector4f to Color.
Fixed bug. Wrong index again.
Added unbind method to BindState.
Wasn't destroying renderables on shutdown.
Added a destroy method on graphics that will clean up everything on shutdown. Added the method call to Application class so it is fired every time the app is terminated. The clean up code was necessary when running a demo from the demo picker. When running the VBO demo twice it would show a black screen. This is because of static initialization and the fact that the VBO renderables have a bind state. Static variables stay around until the classloader is destroyed.
Added reset method to bind state.
