	Fixed these two, but there may well be more ...


> 2) The function GStrHeight (graphics.c) uses the conversion factors
> for the X axis instead of the Y axis. This causes strangeness in
> legend() when the axes are on different scales.
> Fix: Replace fig2dev.bx, win2fig.bx and ipr[0] with
> fig2dev.by, win2fig.by and ipr[1], respectively.

	Fixed and committed.  Updates in 0.60.2
