View source for Manipulating slurs via 'positions and 'extra-offset

There is a command to change slurs, <code>\override Slur.positions</code>. Actually the influence of this command is limited, e.g. if you like the shape of the slur and you want to shift it a little bit,<br />
<code>\override Slur.positions</code> does not exactly what you want.<br />
<code>slurShift</code> shifts the slur exactly the amount you want without changing the shape, <code>slurShiftx</code> combines <code>slurShift</code> and <code>Slur.positions</code>.
