Rectangular apertures in outline break render

[CapnKernel]

Every two weeks, I get a large order from someone who uses "Robot Room Copper Connection":

Sometimes their zips don't render in gerblook. Through bisection I found the reason.

Here's an outline file that doesn't work:

And here's one that does:

The difference is in the aperture definitions:

My guess is that the version of gerbv that gerblook's using is too old to support "R"-type rectangular aperture definitions. ("C"-type circular definitions seem fine)

Thanks very much for the detail that's really useful. Hopefully a new gerbv version is released soon!
