119          happened when gig::Group informations were accessed before
120        - fixed write support for big-endian systems

138          updated when a file is saved (3crc contains sample checksums,
139          einf contains file statistics)
140        - write support: DLSID is now generated on the file and the
141          instruments
142        - write support: improved the default values for dimension region
143          parameters

147          not saved correctly
148        - write support: 24 bit samples can now be written
149        - write support: version 3 is now the default for new files
150        - more write support fixes: the 3ewg chunk is now bigger for v3,
151          dimension regions without mapped samples are now allowed, 3gnl
152          list in v3 files now always has 128 entries, several parameters
153          where incorrectly saved due to an operator precedence mistake
154        - DeleteSample now removes all references to the deleted sample
155        - AddDimension now copies all parameters from existing dimension
156          regions and also makes sure that the samplechannel dimension is

158        - added method GetParent() to class 'DimensionRegion', which returns its
159          parent Region
160        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
161          unused areas

163          of updating lookup tables / caches.
164    
165      * src/RIFF.cpp, src/RIFF.h:
166        - added File::SetByteOrder method

182          velocity (gig v3 feature)
183        - added "smart midi" and "round robin keyboard" dimensions
184        - added new method File::DeleteGroupOnly() which only deletes the given
185          group but moves all its members to another group, the other method,
186          that is File::DeleteGroup() now removes not just the group, but also
187          all the samples that belong to that group
188        - fixed crash which occured on interfering File::DeleteSample() and
189          File::GetNextSample() calls (due to iterator invalidation)

224          instead of the wave chunk
225        - keyswitching dimension is changed from split type "normal" to
226          "bit"
227        - real support for 24 bit samples - samples are not truncated to
