Soldermasks have broken recently

[sowbug]

In this directory there is a zip of Gerber files as well as some images generated by Gerblook on March 26, 2016. If you run that zip through today, you'll note that the soldermask images have the correct board outline but otherwise are missing the actual subtractions from the soldermask.

I noticed this tonight when I was trying to do a new spin of this board. I checked the newest version on http://www.gerber-viewer.com/, and it appears to interpret soldermasks correctly.

Thanks for the report. I'm not sure what's going on there as I don't think anything has changed in the renderer there for quite a while. I'll have a look when I get a chance.
