dotCooCoo 1a77932167 .ai export: the pieces of a warped image write only the pixels they show
The pieces of a Warp effect, an envelope or their expanded art each
held a copy of the whole image in the .ai editing data and in legacy
.ai files: 200 copies for a Warp's 10 x 10 mesh.

- An embedded image cut to a clipping path (in the editing data, also
  an image under an opacity mask that clips) is written whole the
  first time; later copies of the same pixels are written as the
  rectangle the path or mask shows, 2 pixels more on each side, with
  the matrix moved to keep their place. A copy that the path shows
  none of is written as one pixel.
- An opacity mask's window covers everything the mask's art paints,
  its effects and symbol art included.
- An image's editable original and an image in an opacity mask's art
  are written whole. A live Warp's drawn look is not cut to the
  clipping groups around the object, so a clipped image with a live
  Warp reads back with its Warp live.
- When art that held an image's whole copy is left out (an opacity
  mask's art, a live envelope or a definition past the object limit),
  the next copy is written whole again. A whole copy written on hidden
  lines after an earlier one leaves the earlier one as the copy that
  counts.
- The writers read an image's pixels once for the pieces that follow
  one another.
