Check the 12 element vector !map.out

lonmin = !map.out(2)
lonmax = !map.out(3)
latmin = !map.out(4)
latmax = !map.out(5)

But I have a feeling this projection is more complicated than that.
It may work if centered on (0,0), but when centered on (60,0), it
may not behave properly. 'Let me know if you figure it out.
