file.info takes and reports the title, author, author title, description,
keywords, rating, copyright status, notice and URL in one undo step, plus
the read-only created (file.new) and modified (every save to a file) dates;
junk values are refused. Document.metadata (DocMetadata) round-trips
natively. PDF export writes author, subject and keywords to the info
dictionary and XMP, PNG export writes tEXt/iTXt chunks, SVG export writes
<desc> and, with the metadata option, every field as Dublin Core. The File
Info dialog (fileInfo, ui.fileInfoDialog) edits it with keyword chips and
star ratings.

DeviceCMYK and CMYK ICC colours import as CMYK and a file painted mostly in
CMYK opens as a CMYK document (with CMYK default swatches); DeviceGray
imports as Gray; Separation and DeviceN inks become global spot swatches
(their 100 % colour from the alternate space: CMYK, RGB, Gray or Lab) that
the art links to at its tint, /All links to Registration and process
colorants make CMYK. Shading stops keep their model and ink links the same
way. Inks mixed in one DeviceN colour, or spaces that can't be told apart,
import as RGB (with a warning for the mix).
document.open takes colorMode (rgb | cmyk) to open any file in that mode,
converted as file.documentColorMode does (its conversion is now shared).

One shared colour visitor (`colorcmds::Recolor`, used by Edit Colors, Recolor Artwork, the Blend
commands, the proxy Invert/Complement and Document Color Mode) maps solid colours, gradient stops
and text runs as before, and now also:
- gradient-mesh points (with fills); Blend grades meshes by their average and keeps their shading;
- embedded images' pixels (`includeImages?`, default on): the image becomes a recoloured copy under
a content key, the original stays for undo and other objects; linked images are left alone;
- the tiles of pattern fills and strokes (`includePatterns?`, default on): one recoloured copy per
pattern saved as a new pattern swatch ("Dots 2"), the original untouched.
Everything stays one undo step; only nodes that change are copied, in one walk of the tree.
- doc: `ImageBlob::map_rgb` (decode, map each distinct colour once, keep alpha, re-encode PNG),
`ImageBlob::content_key` (now also used by image import) and `ImageBlob::png`.
- `recolor.colors` lists mesh points and pattern tile colours too.
- patterncmds: `add_pattern` adds a pattern and its swatch (shared by Make Pattern and Save a Copy).

Document::swatches_iter/_mut, swatch_mut, swatch_group_of, remove_swatch and a copy-on-write
walk over linked solid paints (map_solid_paints) cover every colour group.
