This removes a lot of code and will make it easier to migrate into a new library with Java bindings, etc. - The clipping planes and projection matrix were unused, removed them. - In split view mode, our demos were using only 2 of the 3 manipulators, removed one. - Instead of callbacks and update methods, users can simply ask for the current matrix at every frame. - The manipulator's job is to consume mouse events and maintain an "look at" basis, there is no need to store a reference to a Filament Camera.
