[Biopython] arrowhead width

[Iddo Friedberg]

Hopefully the attached png clarifies things.

The arrow shaft can be narrowed using its own argument as you pointed out. I
would like to make the arrowhead width narrower, the part perpendicular to
the track . But you can only be defined using the box rather than an
argument such as arrowhead_width?
