Subject: [PATCH] Audio Wave: skip overlapping segment labels (readable when
 splits are close)

Labels crowded when splits are near each other. Now labels are shortened to S{n} and
skipped if within ~26px (canvas) / 30px (image) of the previous drawn label; notes gated
wider. Lines still drawn for every split.
