Subject: Fixes the reading of the positions property in tuplet-number.cc.
X-Git-Tag: release/2.15.14-1~13
X-Git-Url: https://git.donarmstrong.com/?a=commitdiff_plain;h=71da6417b8defa33c6c5a2a6ace29d5666e5c1cf;p=lilypond.git

Fixes the reading of the positions property in tuplet-number.cc.

Positions can theoretically be "empty" if the left is higher than
the right.  Thus, to find its center, we don't use the interval
center function and instead find the center manually.
