[gradsusr] spatial shifts

[Davide Sacchetti]

if you are using opengrads you could develop an extension that allows
for displaying x=x-1, y=y-0:
display shift(variable,1,0)

I wrote such an extension, find it attacched

you should place the extension in a place
like ...grads-2.0.2.oga.2/Contents/Linux/Versions/2.0.2.oga.2/x86_64/gex/

then add this line to file udxt:
udf  0  shift      f_dvd      ^libdvd.gex   "shift(grid,xshift,yshift)
by davide"

it should work
Bye
