Background Layer Controls (position, rotate, scale)
Currently the background image is simply projected as is with some basic controls for choosing between scale modes (crop, fit, or scale). Controls would allow you to position, rotate, and scale the background image freely in relation to the camera.

if you add the 3d asset "plane"
then add your background image to that asset... file/import/place graphic on model
you can kind of cheat the background image as a 3d scalable, movable image.
I wish it were more intuitive how to center or scale the background (zoom in and out would behelpful). A free floating background you can center and scale function would be awesome.
I would love if I could, move, reposition and most of all resize the background accordingly.
