* bugfix: refuse RIFF::Chunk::Read() in case chunk has just been added,
  that is not written physically yet (#82)

10 schoenebeck 1851 - bugfix in Sample::LoadSampleData*(): reset sample read position to
11     sample start before trying to (re)load sample data from file (#82)
12 persson 1627
13 persson 1678 * src/RIFF.cpp, src/RIFF.h:

59     instrument constructors
60     - clear unused fields when saving samples and regions
61     - fixed write support bugs: v3 dimension limits and chunksize

76     instruments
77 persson 1218 - write support: improved the default values for dimension region
78     parameters
79 persson 1247 - more write support fixes: crossfade parameters were not saved,

85 persson 1266 - more write support fixes: the 3ewg chunk is now bigger for v3,
86     dimension regions without mapped samples are now allowed, 3gnl
87     list in v3 files now always has 128 entries, several parameters
88     where incorrectly saved due to an operator precedence mistake
89     - DeleteSample now removes all references to the deleted sample
90 persson 1301 - AddDimension now copies all parameters from existing dimension
91     regions and also makes sure that the samplechannel dimension is

273 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually

324     * packaging changes:
325     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name

357 capela 168 Version 0.7.1 (2 Jul 2004)
358    
359     * packaging changes:
360 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
361     Redhat packages
362 capela 168 - header files included on installation.
363     - autotools-generated files removed from CVS repository.
364 schoenebeck 186 - added support for generating Debian packages
365     - version of shared library can be set in configure.in
366    
367 schoenebeck 58 Version 0.7.0 (3 May 2004)
368    
369     * general changes:
370     - various big endian specific corrections
371     (successfully tested now on PPC)
372     - minor adjustments to avoid compile errors on some systems
373     (using now pow() instead of powl() and --pedantic g++ compiler switch)
374     - libtoolized the library
375     - added man pages for the command line tools
376     (gigextract, gigdump, dlsdump, rifftree)
377    
378     * src/gig.cpp, src/gig.h:
379     - fixed bug in decompression algorithm which caused it not to detect
380     the end of a stream
381     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
382     takes the MIDI key velocity value as an argument and returns the
383     appropriate volume factor (0.0 ... 1.0) for the sample to be played
384     back, the velocity curve transformation functions used for this are
385     only an approximation so far
386     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
387     'Sample::LoopSize' which reflected wrong values
388     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
389     measured in sample points instead of byte offset
390     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
391     'Sample::FineTune'
392     - added class attribute 'Sample::LoopSize'
393     - added method GetInstrument(uint index) to class 'File'
394     - added ReadAndLoop() method to class 'Sample' which is an extension to
395     the normal Read() method to honor the sample's looping information
396     while streaming from disk
397     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
398     'eg2_ctrl_t': replaced this huge enumeration by a structure which
399     reflects the MIDI controller number in case of an ordinary control
400     change controller (this saves a huge switch-case block in the
401     application of the library user)
402     - renamed following attributes in class 'DimensionRegion':
403     'AttenuationContol' -> 'AttenuationController',
404     'InvertAttenuationControl' -> 'InvertAttenuationController',
405     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
406     - minor fix in API documentation for method GetVelocityAttenuation() in
407     class 'DimensionRegion'
408    
409     * src/RIFF.cpp, src/RIFF.h:
410     - added additional API documentation
411     - minor fix in Chunk::Read() method (only a minor efficiency issue)
412    
413     * src/gigdump.cpp:
