fontsize and 'boldness'

[Ruud van Silfhout]

Hi,

Working with lilypond 2.2.0 I noticed that the default fontsize of 
the texts (at least Lyrics, but other text as well?) has 
changed. How do I change that?

What I also noticed is that the letters are 'fatter'.  In the hymne book 
I am working on, this results in a huge difference between lyrics in the
music and verses added to it with LaTeX. Can someone tell me how
I can change that. Perhaps in standard LaTeX text a bit more and
in lilypond a bitt less. 
I use LaTeX with the follwing packages 
\usepackage{geometry,ifthen,graphicx,amssymb,extsizes}
The rest is standard LaTeX text.

in lily I use 
    \override Score.LyricText   #'font-size = #3 


Thanks,
