+Also, as the tqft pic uses nodes internally, if you use the \Verb+transform shape+ key on the pic, you might find you need to use \Verb+every node/.style={transform shape}+ as well.
 \item There is an additional \Verb+every tqft+ key which is run when the \Verb+tqft+ key is invoked (which might be via some other key).
 This is better placed than the \Verb+every pic+ key since that applies to a surrounding scope rather than to the \Verb+pic+ itself.
