was previously part of the mosaic module.
* Fix random characters problem in RSS filter.
* Add rotate-deciangle for more precision on rotate filter
* Support for Intel SSE2 intruction set in chroma converters
* Improved use of Intel MMX intruction set in chroma converters
Audio output
* Replay gain support.
