      Description

      See also QCICS-32

      the preview may be a png with no well defined resolution
      then the only sensible unit for the ctm translation is pixels

      Option a: all ctms for png images are in pixels (also avoids rounding issues when translating back and fort)
      Option b: all ctms for png are in points and the png must internally provide a resolution
