Now: as any JSON/etc user would expect, the QPoint structure should
be stored as a 2-field node:   [ 10, 10 ]   or   { "x": 10 , "y": 20 }

I asked this before as it is not documented, but I still do not have
an answer: what exactly does it take to achieve this ?

have

adds

What is really being asked for here is (yet another) different interface
for editing a ptree container in memory....
