This Script creates a free camera from the current view which has a plane attached.
- Asks for a bitmap input and creates and assigns a self illuminated material to the plane.
- Looks for the image aspect ratio of the current scene and creates the plane according to that.
-Plane stays at the far range of the camera (you can simply change the location by changing cameras far range value)
-Plane always stays filling the current render area, even if you transform the camera, change the focal length or change the far range value.
