Piotr is right, the new global variable LABEL_HAS_PONTER provides info about the pointer on/off state. We use that in the condition for the 2 symbol types.
It is the same as the old (deprecated) LABEL_CUSTOM_ARROW – but the meaning is reversed (OFF used to mean value 1 in the old global, and now it returns 0, and vice-versa).
