Subject: Use cached path length from occupied_tracks
X-Git-Url: http://git.tdb.fi/?p=r2c2.git;a=commitdiff_plain;h=5b71cb905051d654c150cb0e098cade0cb502105

Use cached path length from occupied_tracks

TrackType::get_path_length is not only a function call but also loops
through all parts to calculate the length.
