http://code.google.com/p/lilypond/issues/detail?id=1320#c35Patchy the autobot says: Again, lots of small changes across the bar. The shifts for repeats appear fixed. breathing-sign-ancient.ly looks like it is losing the third breathing sign, however that may be a rasterization artifact of the regtest checker. There are small effects like isolated letters in text shifted likely by one pixel. That makes it likely that we are seeing the effects of rounding/quantization artifacts. Are there some calculations done in C++ that use integers and/or rounding? I would suspect that those are probably done with exact numbers or reals or different rounding modes in Scheme. Remember that (/ 1 2) yields 1/2, not 0 in Scheme.
