tex strings output

[Han-Wen Nienhuys]

Hi Werner,

I've put the first component of TeX generated text metrics in place

        byrd:~/usr/src/lilypond$ !li
        lilypond -f texstr f
        GNU LilyPond 2.5.4
        Processing `f.ly'
        Parsing...
        Interpreting music... [2]
        Preprocessing graphical objects...
        Calculating line breaks... [2]
        Layout output to `f.texstr'...

        byrd:~/usr/src/lilypond$ cat f.ly

        \version "2.4.2"

        { \time 2/4 s2-"foo" }
        byrd:~/usr/src/lilypond$ cat f.texstr
        (globalscale 1.75729901757299)
        ("ecrm10" 0.569055118110236 "Engraved by LilyPond (version 2.5.4)")
        ("ecrm10" 0.569055118110236 "1")
        ("ecrm10" 0.569055118110236 "")
        ("ecrm10" 0.569055118110236 "foo")
        ("feta-alphabet20" 0.569055118110236 "4")
        ("feta-alphabet20" 0.569055118110236 "2")

as you can see, I used a lispish format for now.  The format is :

  (FONT-NAME MAGNIFICATION TEXT)

where MAGNIFICATION is relative to globalscale. Of course, this format
can be changed to taste.  If you can define a standard format for TeX
input, write macros for dimension handling, and provide a TeX output
like

  (FONT-NAME MAGNIFICATION TEXT BBOX-LIST)

then I can start to work on importing the metrics back into LilyPond.
