412     takes the MIDI key velocity value as an argument and returns the
413     appropriate volume factor (0.0 ... 1.0) for the sample to be played
414     back, the velocity curve transformation functions used for this are
415     only an approximation so far
416     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
417     'Sample::LoopSize' which reflected wrong values
418     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
419     measured in sample points instead of byte offset
420     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
421     'Sample::FineTune'
422     - added class attribute 'Sample::LoopSize'
423     - added method GetInstrument(uint index) to class 'File'
424     - added ReadAndLoop() method to class 'Sample' which is an extension to
425     the normal Read() method to honor the sample's looping information
426     while streaming from disk
427     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
428     'eg2_ctrl_t': replaced this huge enumeration by a structure which
429     reflects the MIDI controller number in case of an ordinary control
430     change controller (this saves a huge switch-case block in the
431     application of the library user)
432     - renamed following attributes in class 'DimensionRegion':
433     'AttenuationContol' -> 'AttenuationController',
434     'InvertAttenuationControl' -> 'InvertAttenuationController',
435     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
436     - minor fix in API documentation for method GetVelocityAttenuation() in
437     class 'DimensionRegion'
438    
439     * src/RIFF.cpp, src/RIFF.h:
440     - added additional API documentation
441     - minor fix in Chunk::Read() method (only a minor efficiency issue)
442    
443     * src/gigdump.cpp:
444     - added printout of samples' looping informations
