This signal is sent out to collect variables that can be used to display text in PDF ticket layouts.
Receivers are expected to return a dictionary with globally unique identifiers as keys and more
dictionaries as values that contain keys like in the following example::
return {
"product": {
"label": _("Product name"),
"editor_sample": _("Sample product"),
"evaluate": lambda orderposition, order, event: str(orderposition.item)
}
}
The evaluate member will be called with the order position, order and event as arguments. The event might
also be a subevent, if applicable.
