5Tracks objects with state that needs to be reset when the graphics context is
6modified (for instance, when switching between windowed and full-screen mode
7in SDL builds). This means re-uploading all textures, and also resetting any
8display lists relying on old texture names. All objects which have display
9lists must therefore register with the OOGraphicsResetManager on init, and
10unregister on dealloc.
