Bring the README's features and standing up to 0.19.0

The develop paragraph counted eighteen operations fused into one
dispatch, before the view transform made nineteen and a detail stage
made the fusion two passes, and said nothing of editing on the scene
with Tone Mapping last. Presets are now a menu on the tool rail, a
panorama frame can be left out, and a linear DNG larger than one
texture develops. The requirement count and coverage are
traceability.md's (193, 85.5%), and tiled rendering is no longer
wholly unbuilt. outstanding.md gains its sweep note for 0.19.0 and
says in §11 what the frame choice changed.
