c18cac642b Ray-caster: generalize depth sorting
Switch from a hard-coded sorting network for four fragments to an
insertion sort, which should work for any number of fragments.

b9587872d3 Ray-caster: don't bother clearing the screen
The ray-caster triangles cover the whole viewport, so they'll completely
overdraw the previous frame.

766d56027c Ray-caster: move shaders to separate files
This properly reflects the modularity of the code, and it simplifies
indentation and syntax highlighting.

To get the right order, flip the sign of the `z` component in the output
of the projection map.

1fbeb23194 Add rotation control
In the process, find and correct an error in the --+ vertex, which was
miswritten as ---.

660f42b31f Automatically generate externals.js from package-lock.json
This commit adds a utility to parse package-lock.json and write the proper
  contents of externals.js to standard output. In addition, if the utility
  (src/helpers/pkglock_to_externals.litcoffee) is invoked with a --doc option,
  it instead emits a Markdown bulleted list of all of the external dependencies.
