                                    Everything but the settings button switches the tool, so aiming for the
                                    small switch is optional. The button spans that part of the row, which
                                    keeps the settings button outside of it without any event plumbing.

                                            The switch only shows the state; the surrounding button does the switching.
                                            It therefore takes no pointer events at all: its label reaches past the visible
                                            switch and would otherwise swallow the clicks landing in that strip.
