pdftex bugs

[Mats Bengtsson]

Hi,

The CVS update by Han-Wen from yesterday night solved the 
basic problems with the pdftex output format, now it is 
possible to run
lilypond -fpdftex file.ly
pdftex file.pdftex
at least for simpler pieces of music. 

However, it just took me a couple of minutes to find 
examples of bugs:

- For one of my files, Lilypond died with:
Backtrace:
In unknown file:
   ?:  0* [pdftex-output-expression (placebox # # #) #<output:
wesstromI.pdftex 3>]
   ?:  1* [display ...
   ?:  2*  [eval (placebox # # #) #<directory # 40660790>]
   ?:  3*  [placebox 114.014565798551 -6.0 ...
   ?:  4*   [dashed-slur 0.12 0.6 ...]
   ?:  5    [embedded-pdf (dashed-slur 0.12 0.6 ((# . #) (# . #) (#
. #) (# . #)))]
   ?:  6    (let ((os (open-output-string))) (pdf-output-expression
expr os) ...)
   ?:  7*   [pdf-output-expression (dashed-slur # # #) #<output:
string 88a2e18>]
   ?:  8    [display ...
   ?:  9*    [eval (dashed-slur 0.12 0.6 ...) #<directory (scm pdf)
40664880>]
   ?: 10*    [dashed-slur 0.12 0.6 ...
   ?: 11*     ((# . #) (# . #) (# . #) (# . #))
   ?: 12*     [0.9105 ...

<unnamed port>: In expression (0.9105 . 3.75):
<unnamed port>: Wrong number of arguments to 0.9105


- For another file, I did get a .pdf file but Acrobat
  complained on one of the pages, first with 
  "There was an error processing a page. Too few operands."
  then a second warning with 
  "An unrecognized token '-8.29750640731569e-4' was found."
  I could try to find a small example where this happens
  if this information isn't enough.

I'll try to add a corresponding pdflatex option to 
lilypond-book that runs lilypond -fpdftex on the 
music to be included in TeX form and an additional
epstopdf on the music to be included with \includegraphics.
