obey measures with eps backend

[fiëé visuëlle]

Hi there!

I'm just trying to fix the LilyPond moduke for ConTeXt to work with  
e.g. the latest 2.9;
the module works similar to lilypond-book.

My problem is, that the EPS is always too big, i.e. much bigger than  
defined.

My LilyPond snippet has
linewidth = 341.43306\pt
but the EPS and PDF are 541 pt wide.

The whole score is uniformly scaled, it's not only a problem of the  
linewidth.

1. Why?
2. How can I avoid that?

I call lily like this:
lilypond -b eps -f eps test.ly && epstopdf test.eps
(BTW: How can I avoid all that useless intermediate and additional  
files?)

My snippet header looks like this (mostly stolen from lilypond-book):
\version "2.9.9"
#(set! toplevel-score-handler print-score-with-defaults)
#(set! toplevel-music-handler (lambda (p m)
        (if (not (eq? (ly:music-property m 'void) #t))
        (print-score-with-defaults p (scorify-music m p)))))
#(ly:set-option (quote no-point-and-click))
#(define version-seen #t)
#(set-global-staff-size 16)
\paper {
        #(define dump-extents #t)
        raggedright = ##f
        indent = 0.0\pt
        linewidth = 341.43306\pt
        vsize = 506.45908\pt
        printpagenumber = ##f
}
