Lily 2.7.13 released

[Han-Wen Nienhuys]

Hello,

I'm uploading 2.7.13 as I write this.

   * This release features slashed numerals, plus signs and
     interruptible extender lines for figured bass. Merging of Figured
     bass lines has been made switchable with the
     figuredBassCenterContinuations property.

   * Subproperties, like the `details' field of `Slur' and `Tie' may
     now be tuned with `\override'. For example,

     \override Stem #'details #'beamed-lengths = #'(4 4 3)

     shortens the stems in beams.

   * For each grob, a subproperty in `callbacks' property defines the
     procedure which computes it. This is major internal cleanup, which
     also provides advanced tweakability for power users. For example,

     \override Beam #'callbacks #'direction
       = #(lambda (grob)
           (if (> 4 (ly:grob-array-length (ly:grob-object grob 'stems)))
               DOWN
               UP))

     With this code fragment, the direction of a beam is decided to be
     up or down, depending on the number of stems in the beam.

In short, 2.7.13 has had some brain-surgery done. Expect some glitches 
if you use this version.


The MacOS and Fedora packages are available. Windows and Linux/x86 
packages will follow, hopefully soon.
