Emmanuel BENOîT 6557d369eb Sequencer - Selecting inconsistent overrides
If an inconsistent override (i.e. an override that has segments of
different lengths or durations) is selected, it will be modified in
order to make it consistent. Also, if some (but not all) of the inputs
are missing segments or points, they will be added.
