Lilypond is slow. At the moment we're still breaking and rebuilding
crufty parts. Most of the new code has not been optimized for speed.
I hope we get 'round to that. (Should you try a more recent 1.3,
please send me some timing results. We overhauled the font-selection
code, and I'm curious if the code is as slow as I suspect it is).

try this (untested)

The code to prevent collisions with stafflines had some problems. I
made some fixes in 1.3.98.
