annotate decoders/libmpg123/dct64_altivec.c @ 591:8faf61a640f0 tip

Resynced fixes for unit conversion bugs in the Ogg Tremor decoder from SoundDecoder/ALmixer. Ogg Vorbis uses seconds and we multiply by 1000 to convert to milliseconds. But Ogg Tremor already uses milliseconds but I was still multiplying by 1000.
