3 people 464a442802 PDF/X-4: RGB images carry sRGB, no image interpolation, pdf:Trapped in XMP (#223) ...

- An RGB image with no ICC profile of its own was written as DeviceRGB
  under the CMYK output intent, and the export only warned. In PDF/X-4
  it now carries the sRGB profile (assets/icc/sRGB-v2-magic.icc, ICC
  v2.1, CC0). JPEGs stay passed through. Untagged PNG, GIF and WebP,
  and the decoded TIFF, BMP and PSD fallback, go in as RGB with the
  profile. A re-encoded JPEG keeps the source's RGB profile or gets
  sRGB. Grey images and images with their own profile are unchanged.
- Every image constructor asked for interpolation. PDF/X-4 and PDF/A
  exports now write images without it, which also removes the
  ImageInterpolation error that stopped PDF/A exports with a placed
  image. Plain exports keep it.
- make_pdfx4 writes pdf:Trapped False into the XMP, matching
  /Trapped/False in the document information.
- check_pdfx4 reports an image that asks for interpolation.
