[ncl-talk] problem with cnFillPalette

Hi Francesco,
When you use cnFillPalette, it spans the color map by default.
The warnings are coming from:
res at gsnSpreadColors = True
which is the same idea, but based on an old color scheme that was
deprecated when cnFillPalette was introduced.
Try deleting or commenting it out. I will see if we can make the
documentation more clear on this.
