[Woody] Image widget

[Harald Wehr]

I'm currently testing the new woody framework. In our application we 
need an input field of the type _image_ as it is specified in the 
HTML401 specification:

http://www.w3.org/TR/html401/interact/forms.html#input-control-types

This input field is like a normal submit button. If the user performs a 
click on it the submitted data includes name.x=xvalue and name.y=yvalue 
parameters which represent the coordinates of the click within the image.

Do you have any hints for me how this could be implemented in woody. Do 
I have to make a new widget type? Would it be good to inherit from the 
submit widget?

I'm looking forward to any hint or suggestion on this topic.
