John,

I agree that regionmask should take multiple regions
and do a union of them all. It's relatively easy to
make this change and we'll do it. Meanwhile, as you
guessed, you can use the regionmanager union operation
to all together all the regions.

r := drm.union(wpoly1, wpoly2) # Region is union of 2 polygons

Regards,

Tim

First, this is what Tim said about constructing unions of regions. I
verified that it did indeed make a complex mask of the proper shape
when I used 13 regions, but I am not sure if it worked, since my point 
sources didn't clean well. I never determined if this was b/c of bad
data or bad operation of clean.
