@*
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.
*@
@*
A checkbox rather than a switch, because this row is one entry of a set the
user picks from, not a setting of its own -- the same question the data source
selection next to it asks, and it should not look like a different one.
The checkbox only shows the state; the surrounding button does the switching.
It therefore takes no pointer events at all: its label reaches past the visible
box and would otherwise swallow the clicks landing in that strip.

A caption renders as an inline span by default, and an inline element
cannot be justified. The div makes it a block of its own.
