Same treatment as the branch's `as_chunks` commit (Rust 1.99's
`chunks_exact_to_as_chunks` lint) for the flattener's coverage pass, the
CMYK ink compositor, the Flattener Preview highlight and four test helpers.

Window > Graphic Style Libraries and the Graphic Styles panel's library button open
read-only libraries of original styles generated in code (Shadows and Glows, Outlines
and Rules, Hand-Drawn, Gradient Finishes, Shape Effects, Blends and Transparency) in
the shared library panel. Clicking a style adds it and applies it to the selection as
one undo step (Alt: on top). Save Graphic Style Library writes .vcstyles JSON (styles
unlinked from swatches, with the patterns they paint with) to the user library folder
(User Defined) or a file; Other Library loads one, or another document's styles.
Commands: graphicStyle.libraries, graphicStyle.library, graphicStyle.addFromLibrary,
graphicStyle.saveLibrary, graphicStyle.loadLibrary; UI: window.graphicStyleLibrary
(.other), ui.saveGraphicStyleLibrary, window.userGraphicStyleLibrary1-10. The user and
loaded library bookkeeping is shared with swatch libraries.
