Give FTouchManager the option to raycast touch positions onto a plane

[MattRix]

In other words, make it so that if the Futile scene has been transformed in 3D (ex. rotated or scaled), that the touch values would still be accurate to where they are happening in the Futile scene. Currently the touch positions are relative to the actual screen, rather than the scene itself.

In theory, this would also give the benefit of letting non-Futile objects claim touches before they reach Futile.

I am doing this way to get the ray, but I wonder if there is any shorcut or better way:

def CameraRay ( touch as FTouch):
  //the offsets account for the camera's 0,0 point (eg, center, bottom left, etc.)
  offsetX = -Futile.screen.originX * Futile.screen.pixelWidth
  offsetY = -Futile.screen.originY * Futile.screen.pixelHeight
  //reverse futile transformations... for now
  pos = Vector2(touch.position.x* Futile.displayScale - offsetX, touch.position.y* Futile.displayScale - offsetY)

  return Camera.main.ScreenPointToRay(pos)
