Title: Add resolution option when saving image

Two units systems are added to the ImageInterface : Pixels per cm and Pixels per inches.

Resolution option works only with Imagick or Gmagick as GD is web-oriented and does not handle image resolution headers.

Resolution is important when importing image documents in publication format such as InDesign, Xpress, illustrator, for scaling.
