map projection in Ferret

[Tony Jolibois <tjolibois@xxxxxx>]

         Hi all,

With Ferret we can plot field in a lot of cartographic projection, like 
Mercator, Bonne etc...
But there is not the simplest of them, the "geographical projection", 
x=longitude y=latitude ?

I tryed to change one of the mp_$projection.jnl script in order to have 
this geographical projection, but have problem with mp_fland and 
mp_land, can anybody help me ?

Thanks in advance,
Tony
