Off-topic: Oliver is exporting/engraving to a fixed-resolution png. An alternative is to export scalable vector graphics of the score to PDF.
PDF does scale better, but it does not help because I need the original size embedded.
Logically it works fine when full staves are rendered (at least they all have an identical scaling factor then), but I often have very small snippets like single bars or fretboard diagrams.
