barlines through a Scheme interface.

Patchy 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.
