[Edu-sig] turtle coordinates: Y increase downards - as in most graphics API?

[Jurgis Pralgauskis]

Thanks,

would be even better, if there were possibility to swich orientation with
mode(...)
https://docs.python.org/3/library/turtle.html#turtle.mode

don't know how to call this mode, maybe 'crt_style' or so?
now there are 'standard', 'logo', or custom 'world'
