I do not recall ever using crt. A grep of the source code suggests that
no user-level functions ever refer to it either. In other words, it
appears to be basically unimplemented.
Specifically with regard to text in the margins of a base plot, in
addition to every function ignoring crt, only the text() function
listens to srt (and that draws in the plot region, not the margins);
mtext() (for margin text) only listens to las, so can only do horizontal
