 Single-line fills each line as far as it goes. Point type and type on a path have no line width, so both composers
 give the same result there. A paragraph whose characters differ in line metrics (type size, font, leading or vertical

+where the lines above it put it, across the line's own height, so a taller line that reaches where the frame is
+narrower, or beside a wrap object, gets the room there. Such a paragraph falls back to Single-line when the frame has
+no room for all of it, or when the search for its breaks passes VectorCraft's own limits (1,000,000 lines tried and

 The UI command `type.lineComposer` (Cmd+Alt+Shift+C, in remote mode `press_key {key: "C", mods: {cmd: true, alt: true,
 shift: true}}` or `invoke_menu`) sets `singleLine` when every paragraph of the selected type (or every paragraph the
 Type tool's selection touches) uses Every-line, else `everyLine`, and returns the composer it set.
