API Changes

The changes from a decompressor's (indeed, the entire sound chain's) perspective include support for extended forms of the SoundComponentData and SoundParamBlock records. Additionally, a client can now pass this information to the sound channel by using an extended form of the ScheduledSoundHeader with the scheduledSoundCmd.

This section describes each new structure that is available in Sound.h.
