The best thing to do would be to make a patch for the flow.c,
flow-ortho.c and flow-poly.c that changes the FLOW_ARROWLEN and
FLOW_ARROWWIDTH from hardcoded constants to properties.  That would
require the sizes to be stored on the relevant objects and be
initialized correctly, but the property system should take care of most
of it.  There are plenty examples of this and some documentation at
http://faemalia.org/wiki/view/Technical/DiaEditor.

For that, sure.  Doesn't seem to have been touched for a while.  Please
do open a bugreport on it on bugzilla.gnome.org, so we can keep track of
the progress.
