I think if no widget had more than one of these options, unifying them 
to just -variable would be OK, since the widget would then define the 
"type" of the variable. But there are widgets like [radiobutton] that 
get their label text out of -textvariable and use -variable to store 
their current value, so at least -textvariable needs to stay.
