they are now done with region fades, rather than separate objects. After this commit, Ardour will try to convert your session files to the new crossfade format, but will make a backup in your session folder first. If you have works in progress using Ardour 3 it is ***STRONGLY RECOMMENDED*** that you back up session files before updating to this commit. git-svn-id: svn://localhost/ardour2/branches/3.0@11986 d708f5d6-7413-0410-9779-e7cbd77b26cf
