Renamed matrices. I quite like names such as 'modelToWorldMatrix' and 'cameraToClipMatrix' because they were very explicit about what the transform was doing. However OpenGL uses common terms such as 'model matrix' and 'projection matrix', so other people wlil be able to follow the code more easily if we stick to these conventions.
