	@brief The dialog which edits a cable once it is drawn.

	Everything it holds belongs to the cable itself rather than to the
	line which was drawn: whatever is typed here applies to every section
	of that cable, on every folio, and the conductors it feeds get their
	cable field worked out again as soon as it says it changed.

	Under the count of cores it lists the cores of the type which stand
	nowhere on the sheet yet: double-clicking one sends it to the very
	line this dialog was asked from, which takes the mouse until he
	clicks and leaves the core standing there.
