* \brief Sets the input camera dimensions to match the screen dimensions of a perspective at given zPosition.
* In order for input to be read correctly, an orthographic camera must be used. If you wish to render your game using a perspective camera, this method allows you perform all rendering via perspective camera while still receiving input through a separate #inputCamera. The #inputCamera should be set to Cull nothing, and clear Depth Only. In addition, the orthographic camera should have the same coordinates as the rendering camera. The easiest way to do this is simply to parent the orthographic camera to your perspective cam.
