Commit 137c88880d63ec9f78975af760db335dc4df95fa
2000-03-17T12:47:49
updated the "smooth" anti-aliaser. By increasing the number of segments used to decompose a bezier curve, we get rid of the "fuzz-fuzz" factor. it's also faster than the standard renderer after tweaking. Note that it isn't completed yet..
