0006
0007 identical_bbox_cheat:true
0008     when the elv selection SBitSet has all bits set it means
0009     there is no selection so identical:true
0010
0011     In that case have observed small 0.002 mm shifts in
0012     large bbox dimension values as a result of the copy :
0013     causing CSGCopyTest.sh to fail when using exact comparisons.
0014
0015     As a shortcut to fixing the small bbox shift issue
0016     can instead cheat and copy the bbox from the src when it
0017     is known that there is no selection being applied.
