Commensurate axis scaling

If the `\COMMENSURATE` qualifier is used, the axes will be drawn with commensurate scaling, that is, the lengths of both axes will be adjusted to give a commensurate graph. The lengths of the axes are adjusted at the time the `SCALES\COMMENSURATE` command is given, which means that if you change windows, with the `WINDOW` command, after the `SCALES\COMMENSURATE` command, the axis lengths will be incorrect. Choose the window you want and then set the axis scales.
