You can set the defaults for those as well in a similar way:
sage: line2d.options
{'alpha': 1, 'rgbcolor': (0, 0, 1), 'thickness': 1}
sage: point2d.options
{'alpha': 1, 'pointsize': 10, 'faceted': False, 'rgbcolor': (0, 0, 1)}
So that's the trick. I had been trying to find line.options and
point.options :-)
