412     - fixed bug in decompression algorithm which caused it not to detect
413     the end of a stream
414     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
415     takes the MIDI key velocity value as an argument and returns the
416     appropriate volume factor (0.0 ... 1.0) for the sample to be played
417     back, the velocity curve transformation functions used for this are
418     only an approximation so far
419     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
420     'Sample::LoopSize' which reflected wrong values
421     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
422     measured in sample points instead of byte offset
423     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
424     'Sample::FineTune'
425     - added class attribute 'Sample::LoopSize'
426     - added method GetInstrument(uint index) to class 'File'
427     - added ReadAndLoop() method to class 'Sample' which is an extension to
428     the normal Read() method to honor the sample's looping information
429     while streaming from disk
430     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
431     'eg2_ctrl_t': replaced this huge enumeration by a structure which
432     reflects the MIDI controller number in case of an ordinary control
433     change controller (this saves a huge switch-case block in the
434     application of the library user)
435     - renamed following attributes in class 'DimensionRegion':
436     'AttenuationContol' -> 'AttenuationController',
437     'InvertAttenuationControl' -> 'InvertAttenuationController',
438     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
439     - minor fix in API documentation for method GetVelocityAttenuation() in
440     class 'DimensionRegion'
441    
442     * src/RIFF.cpp, src/RIFF.h:
443     - added additional API documentation
444     - minor fix in Chunk::Read() method (only a minor efficiency issue)
445    
446     * src/gigdump.cpp:
447     - added printout of samples' looping informations
