Storing the vertical skylines of a glyph in a cache instead of recomputing them every time from the beziers. I get the sense that in a score that takes a minute to compile, this'll shave off about a half second for common grobs (accidentals, for example). > "Merging" sounds like O(n^2) unless one takes precautions. > You'd have to look at the skyline code. It looks really concise and elegant to me, but I have no clue if it could be sped up.
