The 1x1 fixture carried an IDAT from a different image: its CRC fails and the
zlib stream is truncated. Chromium and WebKit render it anyway, Firefox reports
"Image corrupt or truncated", and the same bytes sat in eleven fixtures.
Word's in-front-of / behind-text (wp:wrapNone + behindDoc) and ODF's
style:wrap="run-through" both read as a side float, so a near-column-wide
picture reserved its whole height and pushed the text 23-52mm down. They
are a wrap mode of their own now: out of flow at the static position it
was anchored at, z-order from the file (inFront). Both exports carry it
back; tests/unit/wrap-through.test.ts covers the round trip.
The image fixture 72 -> 38 over both formats and 7 pages -> 6, matching
the reference; corpus 1108 -> 1074, no other fixture moved.
