[gradsusr] transparent colours

[Matias Mendez]

Hi Bernd,

I found a script called dshade.gs at at the following link:

http://kodama.fubuki.info/wiki/wiki.cgi/GrADS/script?lang=en#3

That script draws two shading figures. I haven't tested it, but I'm
sending an example output (taken from the above link).

I hope this helps you.  Good luck.

Regards,
Matías
