Compute the left and right padding values needed to format content with the specified contentWidth within a field of the width specified by widthValue using the specified alignment. If Enums::e_ALIGN_DEFAULT is passed to alignment, use the specified defaultAlign instead. Load the computed padding values into the specified leftPadding and rightPadding. If the category of widthValue is not e_VALUE or if the value indicated by widthValue is less than contentWidth, the padding is zero. The behavior is undefined if contentWidth specifies a negative width, or if defaultAlign specifies e_ALIGN_DEFAULT.
