hires: 'boundary' generates a segment for each word boundary, instead of for each character. Which should help:

  • Reduce sourcemap size
  • Easier to find original position in mappings
  • Faster sourcemap merging

From twitter idea: https://twitter.com/dummdidumm_/status/1674102437890621454

Example sourcemap visualization

* If sourcemap locations have been specified with s.addSourceMapLocation(), they will be used here.

Maybe word-boundary to be more specific? Not sure if we are going to have more different type of boundary tho

I'm thinking a shorter name would make it easier to type out when using it. But open to other names too.

magic-string 0.30.2 introduced [the `boundary` strategy][1] for its high-resolution
source map mode, reducing the number of source map segments to align with word
boundaries instead of having a segment per character.
