The editor's page readers decoded every /Contents entry and every form
entry with a fresh 1 GiB allowance, and the reading-order image
inventory added a record per image draw in every form entered, so a few
shared forms drawing each other produced millions of records. Content
streams and form entries are decoded against one per-page DecodeBudget
(content past it is an error, so no edit rewrites a page from part of
its content; forms past it are reported truncated), and an inventory
past 100,000 image draws is refused.
Review on #2994: fill rectangles and the clip were kept as their page-space
bounding boxes, so a rectangle turned or sheared by the CTM could pass as
covering the page while leaving its corners out, and a following fill became
Word's page colour. Each rectangle is now kept as its four page-space
corners, the clip as the rectangles it intersects, and the crop box counts as
covered when its corners lie inside each.

Review follow-ups on #2994: under even-odd any second rectangle, under nonzero
one wound the other way, can leave a hole the Word page colour would cover.
The parity note says the page colour hasn't been opened in Word yet.

A page coloured with Edit a PDF > Background exported to Word as a
white page: export pages carried text and images only, and the Word
section has no page colour.
- pdfcraft-edit `page_background`: the colour of the first thing a
page paints, when that is an opaque fill (no soft mask, Normal blend)
in a plain gray, RGB or CMYK colour, of a path with a rectangle
covering the visible page, not clipped smaller; `None` otherwise.
- `export::Page::background` carries it; the Word writer sets it as
the document background (`w:background`, plus the
`w:displayBackgroundShape` setting Word needs to show it) when every
page shares one non-white colour. Word has one background per
document, so differing colours are left out.
