I agree. I've made a change to make the line thickness equal to about 5%
of the line height - which is more reliable for us to use as there may
be more than one font size on the line. It would be nice to set a
different outline size for each font and size combination, but that
isn't possible when we render the line all in one go, the way ATSUI
recommends. So far I haven't found any problems with adopting this
approach though.
