// Notes
//
// 1. Typ12, this is not ISOB4 which is Typ42, moreover, ISOB4 is
// 2500x3530 and not 2500x3540
//
// 2. New paper were added from here, Additional mappings were
// obtained from [1] appendix B Table B.1.
// Numeric defines were obtained from [2]
//
// 3. Folio for windows is probably 81/2"x13" (letter wide) while for [1]
// it is 8.27"x13" (A4 wide). Here [1] based value will be used but
// mapped to corresponding "windows folio" paper number DMPAPER_FOLIO(14)
//
// 4. [1] folio value gives 594x935 points for 8.27"x13" but 13" are
// exactly 936 points, the value 936 will be used though if ppd implementa
// tor follows exactly table [1] B.1, it can give unmatched papers
//
// 5. [1] and Windows doesn't match, same resolution than note 4.
//
// 6. [1] and Windows doesn't match, [1] value was choosen
//
