cups-filters: updated to 1.28.16

CHANGES IN V1.28.16

- imagetoraster, imagetopdf, libcupsfilters: Added support for
  reading the resolution of an image from its EXIF data when
  loading it. This way we get the image reproduced in its
  original size with "print-scaling=none".
- libcupsfilters: Replaced deprecated data types uint16 and
  uint32. The function to read TIFF image files via libtiff in
  cupsfilters/image-tiff.c uses the deprecated types uint16
  and uint32. The replacements for these types are uint16_t
  and uint32_t.
