Class Camera

A (Perspective and stereo capable) Camera class for Field graphics. The state of a camera is kept in a separate, serializable, immutable class called "state". In contemporary OpenGL all a camera is is something that can produce two Mat4's which were customarily multiplied together anyway. The vi
