Title: A few NumInstances fixes

`NumInstances` recently dropped (correctly, IMHO) a bunch of really poorly behaved instances. Unfortunately, ImplicitCad relied on quite a few of these. Here are a few changes to deal with this temporarily. In particular, the reliance on `Show` is particularly troublesome. This will need a more permanent fix in the future.
