Support MultiCursor with Axes spread over different figures.
As a consequence, the first parameter of MultiCursor (
canvas
) hasbecome meaningless (requiring the user to pass in
[ax.figure.canvas for ax in axes]
seems pointless); just ignore thatargument.
While we're at it, also move some parameters of MultiCursor towards
being keyword-only, to prepare for a hopefully better signature without
the
canvas
parameter at all.Closes #23339 (the signature problem remains tracked at #21496).
