Advanced OGG looping

[Darkhog]

From RPG Maker VX Ace manual:

OGG
These files contain Ogg Vorbis data, an audio compression format with excellent sound quality and compression. Files with playback times three seconds or longer are automatically played by streaming them. For such files, embedding the values LOOPSTART and LOOPLENGTH as comments allows the sample position corresponding to those values to be recognized as a loop.

In layman’s term, this allows for music files that have “intro” part and then they loop, like some module music. Both LOOPSTART and LOOPLENGTH are in samples.

It would be nice if GD would support it, at least in native games.
