Moving dynamics around.

[ralph]

Hi, 
I'm sure that I've seen conversations on this subject recenly but I'll be 
darned if I can find it in the archives so sorry if I'm covering old ground.

I have some dynamics (f, ff etc) which collide with slurs above and I want to 
move them down. There doesn't seem to be a padding option or something that 
would work.

I have tried 
\notes {        
        \once \property Voice.TextScript \set #'padding = #10 c1-\f
}

but this doesn't work, since I assumed that the rendered text must be a 
TextScript.

Any clues please?
BTW, Lilypond 2.1.12

Cheers, in advance,.
Ralph
