[Visualpython-users] fixedwidth arrow

The arrow object has a new attribute, "fixedwidth", which if nonzero forces 
the shaftwidth and headwidth to be what you specify, even if the arrow gets 
very short or very long. The only adjustment made in this case is that if 
the headlength of the arrow is specified to be shorter than half the total 
length of the arrow, the headlength is forced to be half the full length. 
This means that a very short arrow may look something like a thumbtack.
