That's not entirely true. In X, rotations are expressed in the XLFD font
name. E.g. "-*-helvetica-medium-r-*-*-[0 10 ~10 0]-*-*-*-*-*-iso8859-1"
is a 10 pixel helvetica rotated by 90 degrees counter clockwise. This
should work with sufficiently recent X versions (IIRC, it was introduced
in X11R6). Note though, that you will have to position each character
separately.
More info in e.g.

I use this feature in Sketch, both in the Tk-based version and the
GTK-based version.
