Does this let you do things like:

m.weblogo("x.png", res=300)

i.e. an integer, or do you have to use a string:

m.weblogo("x.png", res="300")

One way to "fix" this (if it is a problem) would be to do this:

for k,v in kwds.items():
     values[k]=str(v)

rather than:

for k,v in kwds.items():
     values[k]=v

Anyway, given we have at least ten days until the release (Michiel will 
be away - see his email on the developers list), and this is a little 
change, I would be happy for this to go into CVS now.
