Just to add my 2 cents worth, if you are using a recent build, the bufferer
transformer has a group-by argument, which, if present, causes us to buffer
each line individually, then run the results through an areaonareaoverlay,
and finally do a dissolve. All that happens within the bufferer as soon as a
group-by is specified.
Now, in general, our dissolver requires that the input has no overlaps for it
to work properly. The way to ensure this is to precede any dissolve with an
areaonareaoverlay if your inputs are overlapping.
