Unframed/unbound wall/floor objects

The ability to edit the images in paintings and on the parchment is really cool, but particularly with the paintings/noticeboard, the limited size and surrounding framework can make it difficult to see what the image is, as well as not necessarily fitting into the 'scene'. It would be handy to have basically a blank wall object and blank floor object with no size constraints that can be given a custom image, for things like if you wanted to add a wall carving or a floor mosaic, or something for a room puzzle.
