EPS and .ai import: the note for editing data of another page size gives both sizes and the scale

When the editing data of an EPS or .ai file was for a page of another
size than the file's own page, the file opened as its page or its PDF
part with the reason "its editing data is for a different page". The
reason did not say which page the editing data was for, or that it was
the same page at another scale.

The reason now gives both sizes in points: "its editing data is for a
600 × 400 pt page, not the file's 612 × 792 pt page". When the two
pages are in proportion (within the 0.5 pt per side of the check), it
gives the scale of the editing data's page to the file's instead:
"its editing data is for a 100 × 100 pt page, the file's
1000 × 1000 pt page at 1:10". Every catalog that had the old reason
has rows for both new ones.

     A PDF saved with Illustrator's editing data opens through it as a PDF-compatible `.ai` does, with its layers and groups and with art reaching past its page unclipped; such a PDF holds the data in `AIPDFPrivateData` streams (part of #868). A shape a PDF or `.ai` paints with a gradient (a clip path round a shading) opens as one path filled with the gradient, not a clip group round a rectangle, so Shape Builder, Live Paint and Pathfinder work on its outline (#1304).
     In a `.ai` opened from its editing data, a text object on a layer that shows and doesn't print stays on that layer, made from the file's text document, even where the page doesn't draw it (`crates/eps/src/import/tests_native.rs`). Such a `.ai` opens without the PDF part's warnings that text was kept as outlines when no outlined glyphs come in, and a warning counts the text objects that hold the page's type next to glyphs the page has only as outlines, which don't come in (`crates/engine/src/cmd/fileio/tests_aiimport.rs`). Where the art of a `.ai` or EPS opened from its editing data differs a little from the file's page, the warning gives the share of the page that differs away from type. When that share is 0.2% or less, the warning names the type and gives the share of the page that differs where the type is (`crates/eps/src/import/tests_native.rs`).
     A PDF page whose `UserUnit` (PDF 1.6) is above 1 opens at its size in points, its numbers times the `UserUnit` (one above 75,000 counts as 75,000), and `document.pdfInfo` gives its size and boxes in points too. A `.ai` whose editing data has its artboards in the units of such a page opens from that data at the page's size, with its layers, and when the layers can't be read its pages still take the artboard layout of the data, scaled the same way (part of #1482).
+    When the editing data of a `.ai` or EPS is for a page of another size than the file's, the warning that its layers weren't read gives both sizes in points, and the scale of the editing data's page to the file's page (1:10 for a tenth of its size) when their sides are in proportion (#2034; `crates/eps/src/import/tests_native.rs`).
     A `.ai`, or a PDF saved with Illustrator's editing data, whose editing data can't be decompressed opens from its PDF part with a warning that its layers weren't read and why, and an export or Save As to its own path asks first (`acknowledgeLoss`), as for a file whose layers the reader can't read (`crates/eps/src/import/tests_native.rs`, `crates/engine/src/cmd/fileio/tests_aiimport.rs`).
     PDF export and `.ai` saves write a page with a side longer than 14,400 pt with a `UserUnit` (PDF 1.6), its longer side divided by 14,400 and rounded up to the next thousandth, so that no side is longer than 14,400 units (ISO 32000-1, Annex C.2); in PDF 1.3 to 1.5 files and PDF/X files such a page is written in points.
     Placed (linked) files in a `.ai`'s editing data come in as linked images in their place, each showing the low-resolution preview the file keeps of it until its file is found or relinked in the Links panel (a file found next to the document or at its path is read as the document opens). A file with them no longer falls back to its PDF part, so its guides, sublayers and hidden objects open (#1264; `crates/eps/src/import/ai/tests.rs`, `crates/engine/src/tests_links.rs`). In a file opened that way, a gradient with stops in the middle runs its whole ramp across its shape and a gradient object no longer passes its fill to the next path (#1390); text objects with an appearance keep their own text and frame, type of hidden layers stays hidden, and type on later artboards lands on its text objects (#1391); area type whose frame is too short for a line of the fallback font shows its first line, the frame made taller with a warning in the open result (#1392).
