FVector PositiveBoundsExtension
The properties below are protected to force the use of the Set* methods for this data in code so we can keep the extended bounds up to date after changing the data. Property editors will trigger property events to correctly recalculate the extended bounds. Bound extension values in addition to imported bound in the positive direction of XYZ, positive value increases bound size and negative value decreases bound size. The final bound would be from [Imported Bound - Negative Bound] to [Imported Bound + Positive Bound].
