[NTG-context] MetaFun: textext.origin, thelabel.origin not positioned on baseline

Hello again List, Now I’m making diagrams using MetaFun. The MetaFun manual describes an “origin” option for positioning textext’s and label’s on the baseline. However, this dose not appear to be happening with the code in the manual (below). In fact, the diagram in the manual dose not show

Re: [NTG-context] metafun: circular arc

In the example the text is drawn as: draw followtext(q, "\strut TEXT ONE") it looks as if the \strut generates a space before the text. e.g. if you omit the \strut, the text will align at the start point. In my perception, the \strut is a zero width box, so it should not generate the space
