Curvilinear data, mp_fland, and mp_graticule...

[strandwg@xxxxxxxx (Gary Strand)]

I've been hammering away at trying to get a picture of some curvilinear data 
properly overlaid with mp_graticule, and it just ain't working. The graticule 
lines quit at 0E, as does the mp_fland.

Also, the image longitudinal extent is that of the data itself, regardless of
how I tweak the arguments to mp_lambert_cyl. The jnl file:

let mid_lon = `xmin+(xmax-xmin)/2` ; let mid_lat = `ymin+(ymax-ymin)/2`
