DirectSound output driver for NeoJukebox.
This driver offers a better sound quality than SEAL, but is still buggy.

HISTORY
v1.0    First Version
v1.1    Added panning change
v1.2    Added sample playing ability (not only streamed buffers) for use with
        QSound driver (crashes).
v1.3    Improved volume calculation (I use linear volume but Directsound uses
        Logarithmic attenuation).
        Fixed all the bugs that made the driver crash (I hope).
