Each camera has also following properties not available from Ruby:

bool FieldOfViewIsHeight - whether FieldOfView is measured in the y direction

bool Camera2D - whether a camera is 2D or not
Center2D - 2D Point - center of a camera in 2p perspective mode
Scale2D - double - scale (zoom-in/out) for 2p perspective view

Yes it will work on both Mac and PC.

BUT it is meant for you to copy it INSIDE your plugin sub-module.
