Ui.Path stroke behaviour - modifying the default behaviour

[Phuket2]

I can't remember long ago when I was dealing with macs graphics how stroking a object was handled.
But I see by default Pythonista splits the difference. Meaning if you set the line_width to 2 it will expand by .5 and inset by .5
As far as I can see you can't modify this behaviour to only inset the thickness rather than it being divided over the inner and outer line thickness.
I know I can do it manually, but it complicates compositions of multiple draw functions.
Hopefully, I am just missing something easy.
