The display architecture has support for text rotation, but it has
been disabled in a number of places. Also, the functionality isn't
exposed by any user program (e.g. d.text).
If it would be useful, I can look into re-enabling the rotation
support, and exposing it, either with an option to d.text, or a
separate d.text.rotation program (the rotation persists between

Is there any reason for maintaining the "paint" system? AFAICT, most
of its functionality is available via "ps.map", and Ghostscript
supports far more printers than the "paint" system.
