You seem to be implying that the layers/xt system is an integral part
of System V or the SysV tty interface.  I don't think this is the case.

Do you think that a windowing system running on SysVr3 should support
the layers/xt ioctl for window size?  (I don't mean whether it should
allow such a function, just whether it should use the same ioctl
command code and return the same data structure.)

This question has come up with regard to Commodore's proprietary
windowing system for Amiga Unix (SysVr3); comments are welcome.
