[gradsusr] background color

[Jeff Duda]

For changes to background or display colors, it usually helps to issue the
clear command to figuratively wipe the slate clean before displaying
stuff.  I think the reason your country outlines are not appearing is
because you set the line color to zero, which matches the background color
no matter what the background color is.  Use a different color index in the
set line commands.

Also, I see you are trying to display a field that has underscores in the
name.  As far as I'm aware, that's not allowed in Grads.  Is that
displaying the variable correctly?
