Yes, I think you're right that an svg file is superior to a png file. In the
svg file, all the objects are resolution-independent. So the score and its
components can be scaled arbitrarily without raterizing degradation.

It's remarkably easy to enter these kinds of scores using a MIDI sequencer,
and remarkably difficult to generate these kinds of scores using
conventional computer notation programs. That's why Lilypond is such a
godsend there. At least Lilypond make it possible to generate these kinds of
score.

(To enter these kinds of things using a MIDI sequencer, you just figure out
the number of ticks per quarter-note for each tuplet and enter it. If we're
using a timebase of 480 ticks per quarter-note, then an 12:11 quarter-note
has 11/13(480) ticks, or 406.15 ticks. This means that every 7 13:11
quarter-notes you add one tick. To enter notes of these length in any MIDI
sequencer, you merely choose STEP ENTRY and then pick the note-length, 406
ticks, and enter the note. It's trivial.)

Since the function of the score is for analysis rather than performance,
it's unimportant whether Lilypond crashes as long as we can generate
something that can be patched together as a png or svg file and then
printed.
