- 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
- replace properties "BOLD ITALIC UNDERLINE" by one property FONT_STYLE
- if text is custom fomatted (has size/fontface changes, contains parts in bold/italic etc.
then the appropriate property values are set to "unstyled". This enables the reset button
in the inspector.
- pressing reset for some text properties strips changes of this property in the text
Example: text contains a part in italic: pressing reset removes the italic formatting
- the "remove custom formatting" button is only enabled if there is some custom formatting
The problem is deep in the initialization of staff types in Staff.
This commit also tries to make handling of StaffType more "const correct" and adds some
assertions which may lead to crashes (and helps detecting bad code).
* The one C4100
* The one C4189
* The two C4457
* The two C4701
* The 475 C4267, changing to size_t were easily possible, casting to
int elsewhere
* Fix GCC warnings reg. wrong printf format for a size_t, reg. unused
variables and reg. ambigous else branch, seen on Travis CI
