It's on the To-Do list..., but it should not be that hard I hope.

It should be no problem, but I have not tried it yet either.

Another thing Netscape does is to display partial images as they arrive (nice 
for interlaced gifs).  Wouldn't this be hard to do in Tk?

I also noticed that tkweb gets the base URL wrong when the server sends 
redirect.  This is because $ua->request hides redirects too much for for its 
invoker.  I guess a fix is to maintain the base url as an attribute of the 
UserAgent.  An alternative is to return the base url in the response.  What 
should we prefer?

When I think about it, I guess I would like to put it into the response object.
