- Before: 'OFFSET' = 2nd measure fumenOffset
- After: ('OFFSET'-Full measure duration) = 1st measure fumenOffset
Both methods will produce the same results if no #MEASURE/#BPMCHANGE
commands are present in the first two measures. However, if these
commands ARE present, then you will get wildly different results.
This change doesn't affect 4/6 tests, but for 2/6 tests there were
#MEASURE/#BPMCHANGE commands. For these songs, I had erroneously "fixed"
the OFFSET values, when they were correct all along. So, I reverted them
back to their original values.
Fixes#25.
This PR adds the remaining changes needed to support branching TJA
songs.
- Properly handling `r` (drumroll) based branching conditions
- Handling commands that come after a measure end but _before_ the first
`#BRANCHSTART` command. (This was not previously covered by
`hol6po.tja`.)
As well, it adds a bit of cleanup/refactoring to the changes from the
previous branch PR (#20).
To test these changes, another new branching TJA-fumen pair is added to
the test suite.
