Is there any capability in IDL for making polygons semi-opaque? There
you would set no hidden facet and be able to see one polygon through
another polygon. This would be a useful facility for some spectral
imaging wavebands where materials are semitransparent.

I see in IDLgrPolygon there is a boolean operator for opacity, but i
am interested in partial transparency.

many thanks,
Neil
