Call the tool Compose, since that is what its panel says

The rail entry read "Crop" while the panel it opens is headed COMPOSE and the
button leaving it said "Done Cropping". One mode, three names, and the odd one
out was named after a single control rather than after the decision — which is
what made cropping look like a category of its own in the first place.

Straightening, the quarter turns and the flips are already in that panel, and
perspective will be. `ViewMode.crop` keeps its name: it identifies a canvas
interaction, which is exactly what it still is.

Found by looking at the running application rather than by reading, which is
also how the two halves of this were noticed to disagree at all.
