-/* Create and initialise a state structure, takes a dither type, a number of
- * channels and a bit depth as input
- *
- * The Dither type is one of
- *
- *   GDitherNone - straight nearest neighbour rounding. Theres no pressing
- *   reason to do this at 8 or 16 bit, but you might want to at 24, for some
- *   reason. At the lest it will save you writing int->float conversion code,
- *   which is arder than it sounds.
- *
- *   GDitherRect - mathematically most accurate, lowest noise floor, but not
- *   that good for audio. It is the fastest though.
- *
- *   GDitherTri - a happy medium between Rectangular and Shaped, reasonable
- *   noise floor, not too obvious, quite fast.
- *
- *   GDitherShaped - should have the least audible impact, but has the highest
- *   noise floor, fairly CPU intensive. Not advisible if your going to apply
- *   any frequency manipulation afterwards.
- *
- * channels, sets the number of channels in the output data, output data will
- * be written interleaved into the area given to gdither_run(). Set to 1
- * if you are not working with interleaved buffers.
- *
- * bit depth, sets the bit width of the output sample data, it can be one of:
- *
- *   GDither8bit   - 8 bit unsiged
- *   GDither16bit  - 16 bit signed
- *   GDither32bit  - 24+bits in upper bits of a 32 bit word
- *   GDitherFloat  - IEEE floating point (32bits)
- *   GDitherDouble - Double precision IEEE floating point (64bits)
- *
- * dither_depth, set the number of bits before the signal will be truncated to,
- * eg. 16 will produce an output stream with 16bits-worth of signal. Setting to
- * zero or greater than the width of the output format will dither to the
- * maximum precision allowed by the output format.
