class conflict

There seems to be a naming conflict between two of the stk object
classes:

a <Text> object can be of type <Tk-canvas-figure>. In this case, it is
a canvas item. Or a <Text> object can be a widget of its own.

As far as I can tell, the object that is loaded last is the one that
is created with a (make <Text> ...) command. If it's ok to overload
class defenitions, and I'm just missing something, please tell
me. Otherwise, I'd suggest renaming one of the two classes in the next
distribution.

thanks
