Conflicts resolved onto main's newer shape, and the PR's policy applied to
every alloc_id/add_media/new_slide call site main has grown since: commands
answer bad(cmd, NO_ID_SPACE) (slide.reuse, insert.zoom, SmartArt, photo
album, review.accept, handout/notes masters, master placeholders,
background/artistic/compress pictures, transition sound, ink to shape,
paste special, file.new templates); reid/bring_media/renumber/regenerate
and compare::adopt/accept are fallible; outline import keeps what fit.
Tests use expect() on the now-Option results.

The Picture Format > Remove Background button was a disabled
placeholder. picture.removeBackground now flood-fills from every edge
pixel through similar colours: each step must be close to the pixel
before it (so gradients and soft shadows follow) and to the edge colour
it started from (so it can't leak into the subject). That region turns
transparent with a one-pixel soft edge, and the picture points at a new
PNG; undo brings the original back. Tolerance 0-100 (default 20); the
ribbon offers normal, looser and tighter. Pictures whose edges are all
subject are left alone, and pictures over 16 megapixels are refused.
