lawnjelly ed47570266 BVH - detect shrinkage within expanded bounds
Although the expanded bounds were working in normal use, for moving and growing objects, there was one case which was not dealt with properly - significant shrinkage of exact bounds within an expanded bound.

This PR detects significant shrinkage and forces a new expanded bound to be created.
