Hmmm, my actual function contains this bit ... any idea on how to solve this as
generic as possible? I do not want to make this require or prevent postscript as
the dev, but make the test (postscript) pass and enable future use of postscript
... where to put the 'fonts' unobtrusively, so that other devs will still work?

vectorsequence <- c("A","B")
xreq <- length(vectorsequence)
par(mar=c(1, 1, 1, 1) + 0.1)
plot(1, xlim = c(0, xreq), ylim = c(0, 4), type = "n", ann = FALSE, axes =
FALSE)
text(1:xreq, 2, vectorsequence, cex = 2.5, family="mono",font=2)
