Update on Signed Trills?

[Will Oram]

There are two kinds of signed trills: ones with tiny accidentals on the 
side and those with ones on top. (At least, those are the trills I work 
with...contemporary trill fun is discounted.) It's a tedious process to 
find good parameter values to properly position and size these 
accidentals. Furthermore, because I have to treat 'tr' as a glyph 
instead of \trill, markup padding is applied. This leaves you with a 
trill sign sitting higher up than the signs around it.

Anyone have good code to achieve both these? The last time this 
question was posed was one year ago (and by someone else), and a lot 
has changed, so I'm bringing it up again. See 
http://lists.gnu.org/archive/html/lilypond-user/2004-06/msg00118.html .

PS...at last, a job interview; Han-Wen and Jan might get donation funds 
from me yet! ;)
