- tick names a position on the time axis - tick is always a Fraction() - only Measure() and Segment() (and Tuplet?) have a tick value - tick() for an generic element return only a sensible value if isMeasure() or isSegment() or isSegment(parent()) - "ticks" names a duration stored in a Fraction() - the tick value for an Segment is relative to its measure - rename "duration" to "ticks" - rename afrac() to tick() - rename rfrac() to rtick() - rename some variables, changing "fraction" into "tick" (example: actualFraction() into actualTicks()) - Lyrics ticks are written as Fraction, on read if xmlreader sees a "/" it reads a fraction else midi ticks for backwards compatibility
