Re: Changing/Setting end_arrow from python Again

[Philip Cavaco <Philip Cavaco ki se>]

Could the arrow be set similarly to colour. I mean that just the type
can be specified as a number and the default settings for width and
length are used, 

o.properties["start_arrow"] = 17

or a triple as you suggested. This way we wouldn't have to add the named
enums. We would need a way to find the default width and length values
for a given type though. I am not sure where this information is.
