I'd advise to generate postscript, and then convert the postscript to
png (with transparancy!) using
gs -q -dNOPAUSE -dBATCH -sDEVICE=pngalpha \
-sOutputFile=score-page%1.png -r101 score.ps
(For the best compatibility, run lilypond with --verbose and copy the
'Converting to PNG' command, substituting pngalpha for png16m.)
Maybe LilyPond could add pngalpha as a generation target?
