more of Alexei's findings, to share with the wider community, I hope.
Yes, I remember seeing the "richard's secret instruction" string too. That's
obviously undocumented :-).
ADJUST is documented-ish - it is both 8F and 0x90 .
/* This code adjusts strokes so that their width is closer to the target width.
* Only 1 bit is added or subtracted.
* If the boolean part of the opCode is set, the edge that is moved is specified
* the first argument; otherwise the edge that needs to move the least is moved.
