Ben,
This is a few months old now, but I'm just rejoing this list and am
going thru some old posts...
The reason you're not noticing any difference from specifying a round
endcap style is that this is the default.
As for modifying the buffer algorithm to produce different width
buffers, yep, this is possible, with a bit of work. We'd be interested
in talking if you have funding for this... 8^)
What is your use case for this? Did you just want a set of linestrings
with each one buffered by a different, but constant amount? (E.g.
equivalent to buffering each individually and then unioning them) Or
did you want to buffer a linestring with a varying buffer width along
the linestring? This latter is the more interesting & challenging
case. If that, could you comment on what you'd expect to pass in as
arguments to such a routine? (I.e. how would you want to specify the
varying buffer width?)
