SVG - parse_as_dict

parse_as_dict is a feature by Architetto Francesco Fantoni for the svg library, it lets you get a dict of the shapes in an svg, looked up by their ids.
This lets you use them as libraries of shapes.

Heres the original mail explaining the functionality:

As we don't want to see fragmentation among the libraries it would be good if this could make it upstream back into shoebot.
