Re: Lyrics.LyricText.font-size in layout block

[Colin Tennyson]

Hello tisimst, hello Noeck,

thank you for your replies.

You have explained to me why a very small number, -0.2, has such a noticable
effect.
I infer that Lilypond _replaces_ the step value for the LyricText font-size
with the entered step number (rather than performing an addition.)

So when I entered -0.2 the actual change was from 1.0 to -0.2, which is of
course a noticable change.


For completeness (and because David Kastrup insisted a minimal example
should always be provided) I created a minimal example 
I took a measure of Choir from the snippet repository, and I added a paper
block with one line in it, and a layout block with one line in it

Steps to repeat:
Try it with various values for the override: -1, 0, 1
