piano centered dynamics colliding with barline

[Neil Thornock]

Hi all,
New to Lilypond and so far quite enjoying myself!

I notice that the dynamics in the Piano Centered Dynamics template are aligned too far left, giving rise to collision with barlines when they appear on the first note of a measure.    Is it because they aren't attached to actual notes?  The code shows the incorrect alignments of the Piano Centered Dynamics and then the "proper" alignments when dynamics are attached to "real" notes.

I can adjust the horizontal offsets in the DynamicText override (0.7 appears to be the perfect correction), but then the dynamic collides with the hairpin.  Obviously I can't adjust the hairpin, or I get hairpins running into other kinds of trouble at the other end.

Any fixes for this problem?

Thanks!

Neil
