Re: [Guidolib-devel] sever bug of full rest

[Dominique F. <fo...@gr...>]

The problem is now fixed:
- a clef change doesn't reset the key signature accidentals any more (bug and patch reported by Yu Fan)
- a clef change resets the current measure accidentals (as described by Gould in "Behind bars" p.78)

The change has been committed to the 'mapping' branch.
