library: stand a frame up in the catalogue, wall, strip and studio

The library stage carried no way to correct a frame shot on its side, and
nothing kept the correction. A quarter turn now rides on the catalogue row
(`rot`, beside `star`, carried over by a rescan), the two chips under the
preview step it, and the tile, the strip thumbnail and the stage all read it
through one bake so a frame is never stood on its side in one place and
upright in another. The studio opens a frame at that angle and a turn made
there is filed straight back onto the row, so either end of the turn is
what the frame comes up at next time.
