Fraction of (legend) font size (in points). It was decided that it is
these dimensions are better to be scale with font size.
For example, handlelength=5 means 50 points when legend font size is 10 points.

Right now, public setter method is not supported for these attributes.
While this is possible it is a bit tricky. I need to double-check but
you need to change the dimension of not only the associated artist
(e.g., lines) but also its container (offsetbox).
The current design recommends you to create a new legend (by calling
legend again) if you want to change its attribute.
If this approach is not applicable, please describe your use case.

As of now, some (maybe most) of legend attributes are not exposed is
possible but a bit tricky to do
