Subject: Correct TrackAttachment entry endpoint
X-Git-Url: http://git.tdb.fi/?p=r2c2.git;a=commitdiff_plain;h=2eb07011edab09bc297d81055d8e27315ce7802a

Correct TrackAttachment entry endpoint

Since endpoint direction points outwards from the endpoint, we want to
find one that's as close to opposite to the TrackAttachment's direction
as possible.
