Use this configuration option to make Profound UI revert to its original edit mask support, for backward compatibility.
The original edit mask support will force zeroes into all positions of a numeric value (even if an edit word attempts to remove leading zeroes, the edit mask will put them back.) Newer edit mask support strips the leading zeroes as designated in the edit word. We provide this flag for backward compatibility for those relying on the older behavior.
