3D coordinate to 2D coordinate transformer for Spark AR

This patch will transform the position of any 3D object from 3D coordinate space to 2D screen space. It will take the global position of the 3D object, screen size and screen scale as input, and it will output the projection of the 3D object on 2D screen.
