* The term "navigation sign" is inspired by Wikipedia's article
* on "Dal Segno", which calls it a "navigation marker".
*
* Navigation signs can either be placed at the beginning or at the end
* of a measure column. At the beginning, it is a target sign, i.e. a jump
* ends here and this measure is played next. At the ending, it is an
* origin sign, i.e. the jump is performed from here after the measure is played.
