Hi Bill,
Thanks for the fix on this.  The fixed UnionSet is allowing me to choose 
a ConstantMap color, but when I add an Alpha parameter, it does not 
behave as it should.
Using 2 different filled Irregular2DSets, each with its own ConstantMap, 
I get this:

However, when I make a UnionSet with the two Irregular2DSets and using 
one of the ConstantMaps, I get this:

Even a UnionSet with a single Irregular2Dset wedge produces the same 
produces the latter result.
If you would like, I can send you my test code.
Thanks!

Hi Kevin,
This suggestion works great, thank you!  I have run into another problem
in that I have a set of these wedges (several Irregular2DSets) and I
group them as a UnionSet.
This looks like a bug in UnionSet.java. The fix should be at:

Thanks for finding this.
