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