dotCooCoo 72fb8fe81d Image Tools: masked images count as see-through in legacy .ai and pattern tiles
- The legacy .ai and the check for see-through images in pattern tiles
  read a color-masked image's masked pixels, as the flattener does. A
  legacy .ai flattens a masked opaque image with the art under it, or
  leaves it out with `transparentImages: "omit"`, and a pattern tile that
  holds one is expanded before PDF/X-1a, PDF/X-3 and legacy .ai output
  flatten it.
- Printed separations check whether a colorize paint shows on the masked
  pixels, as the canvas does, rather than on the image's own pixels.
- A saved mask that leaves out `contiguous`, `tolerance` or `softness`
  reads them as the command's defaults: true, 10 and 10.
- Remove Background is unchanged on this branch. Its refusal of a
  grayscale image colorized with a process color is left for a separate
  pull request.

linked image at its preview.
