Comment 2 for bug 166252

There must be an easy solution. If two objects touch each
other, have some code to overide AA and ensure that no gap
is shown between their two touching borders. Maybe this is
dificult to implement for curbs, but at least for straight
lines that should be feasable.

This problem is serious because when I export in PNG this
image, the gaps still show! Thus my banner for a web page
is useless. Please reconsider opening it if only to fix the
PNG exporting facility.
