It's neat that you are generating such precise skylines, but can you
show places where this makes an appreciable difference for texts?

You could look into some heuristic that limits the number of boxes
depending on their shapes, so it creates a single box for most glyphs.

For example, you could take the box enclosing the glyph and compare
its area with that of the union of the boxes, and revert to one box if
the difference is less than X percent.
