'plain' does sound a misnomer, as these slot names are about "what"
are painted, not "how" they are painted. The latter is what their
values represent. Whoever named that slot was confused by the fact
that 'context' (i.e. "what") lines are by default painted in 'plain'
color without frills (i.e. "how").
We usually try to give a brief mention to historical names primarily
to silence those who pick up stale information from the Web, get
curious, and then complain loudly after finding that we no longer
document them even though we keep accepting them silently, so I am
somewhat tempted to do this on top.
