Missing Triangle #69

In the hierarchy demo.

Edit:

This looks like it's a result of incorrect coplanar operation results - specifically with the "frame" component.

Hi, I tried several changes, but if I set the width of the first frame from 2 to 2.1, the issue disappears. I don't understand why, but can it be a solution?

This issue is a bit trickier - adjusting the geometry itself could avoid the problem but ideally the CSG operations should never result in a mesh hole regardless of the shape. So there's something going on in the numerical robustness or something of the CSG computations. I'd like to get #68 and #51 going to help make it easier to track these issues down and fix them.
