There are these very interesting-sounding variables in the RastPort structure
called PenHeight and PenWidth. When I put different values in them, the pen
still draws in normal size. Is there any convention, setup, or non-obvious
trick needed to make them functional? Or are they privileged (if so, what
uses them?) ?

Also, is there any magic needed to make the various software-failure traps
call some abort routine of my own, or is _all_ the relevant info laid out
well in the RKM, etc. I wouldn't want to have to do in-line assembly or much
in the way of BCPL, or figure out compiler-specific solutions by trial and
error.
