[bbrelje]

Description

LocationConstraints1D returns NaN when polyline point values are zero and scaled=True

For example,

Steps to reproduce issue

Please provide a minimum working example (MWE) if possible
Run Test 12 in test_DVConstraints, but turn scaled=True

Current behavior

NaN is returned if the original point location had a coordinate value of 0.0

Expected behavior

Should produce value 1.0 if the point is unchanged from its original location.
Or deprecate this if nobody is using it
