You could try to play around with the spacing constants in 
scm/basic-properties.scm

It seems that staff-position is missing in 
scm/grob-property-description.scm; a bug!

Try piece = "This \{\\sl is\} a test."; (also the backslash
needs an escape).

Hmm, Lilypond asks for cmr of sizes 4,5,6,7,8,10,12,14,16 and 20
whereas a typical teTeX installation includes 5,6,7,8,9,10,12,17.
Either we could change Lilypond to use only these sizes or 
we have to start fiddling with magnifications again.
As a quick hack to implement the former option, you could apply
the attached patch. The result will probably look a bit odd.
