<var>CustomAlignInsertBefore</var> is a <var>Boolean</var> function which
indicates whether the specified controls need to be custom-aligned using the
OnAlignInsertBefore handler. CustomAlignInsertBefore is called (circuitously)

The return value is <b>False</b> if OnAlignInsertBefore has not been assigned
