Hi Fang,
as a rule of thumb, do not add complexity to base models if it is not
needed. As explained already, you can calculate the offset from
the polygon later, so no need to enhance any sal interfaces for a single
filter. The complexity should stay in the filter. Enhancing the
sal layer is for general functionality only.
Changing anything outside of the flash filter itself should only be done
if it makes general sense to have that functionality or if functionality
is missing that is needed to perform a task.
Regards,
Christian
