Log:
Merged revision(s) 23128-23132, 23141 from trunk/OpenMPT:
[Mod] FLAC: Store a zero-length loop in WAV metadata when only a sustain loop is present, similar to how the WAV writer does it. This way, we can distinguish it from a normal sample loop.
........
[Imp] MOD: Identify modules saved with TakeTracker.
........
[Mod] MOD: The last three bytes of the Tetramed tag can vary. Check that they are present but don't verify their contents.
........
[Fix] Compile fix.
........
[Mod] Sample tab: When adjusting sample offsets after resampling, round the result and never set it to 0, as that would just recall the previous offset. Also don't do any adjustments for relative offset commands - it's an unnecessary calculation as they should stay identical.
........
[Mod] XM: Allow to use 128 channels in XM files, as MilkyTracker can write such files as well (https://bugs.openmpt.org/view.php?id=1877).
........
