Weird, Okular (v. 4.13.0) doesn’t display the text in those.
Here’s a comparison with mupdf (1.4):

Whatever PDF magic you worked into there, I hope it didn’t ruin

Does that mean what I think it means? That we can feed arbitrary
Lua code into MP (as strings) and, conversely, grab MP values
from Lua? Also, in lmplib.w, the key “run_script” is exported but
not “script_runner” as the slides claim -- which one should I
trust? Anyways, since I’m not too familiar with MP internals this
is going to take me some time to digest.
