Wind Barb Fill

[Greg Clarke]

Good Day All

Is it possible for GrADS to fill in the 50kt triangle on the wind barbs? It
appears by default that they are left hollow.

A cheat could be to increase the line thickness, but we are converting the
images to PNG and we would loose the clarity of the individual 10kt
feathers.

Many thanks in advance.

Best Regards
