Subject: [PATCH] PDF: an option writes pages longer than 200 in at full size
 in points

The Save PDF dialog's General section gets "Write pages longer than 200 in
at full size in points" (longPagesInPoints in document.exportPdf,
document.export, presets and document.pdfSettings), off by default. When it
is on, a page with a side longer than 14,400 pt is written with its media
box in points and no /UserUnit at every PDF version, and a PDF 1.5 file
stays PDF 1.5. The export's warning for such a page then says it is written
in points. With the option off, and for pages of 14,400 pt or less, the
file is the same as before.

Docs: docs/mcp.md, docs/target-app-parity.md. The new label has a row in
every catalog that lists the dialog's other options.

     In a `.ai` opened from its editing data, an envelope made with a warp, a mesh or a top object opens as a live envelope of its contents, with its warp style, bend and distortions, its mesh points and handles or its top object's outline, its Envelope Options, its Fidelity and whether its contents are being edited. When Distort Appearance is on and the size the file saves for the contents matches their bounds with strokes, the contents map from that stroked box, until an edit in Edit Contents changes how far the strokes reach; VectorCraft's new envelopes map from the geometric box, as do contents with no width or no height, such as a single straight line. An envelope that can't be read, or that VectorCraft draws differently from the file's drawn art, keeps that drawn art, with a note. An envelope of type opens live, its type laid out from the text document as its contents, where VectorCraft's own envelope of that type draws as the drawn art the file saves (compared as for the other envelopes, seen on white and on black, so white type counts, and only where the layers with it are compared with the page and draw as it, the envelope weighed as the art it draws); elsewhere, and where the type's font isn't available, a text or visibility variable binds the type, or the envelope is in a symbol's or a pattern's art, it keeps its drawn art, with its type hidden and a note that says the type isn't editable (#3179; `crates/eps/src/import/ai/tests.rs`, `crates/eps/src/import/tests_native.rs`). A warp of type whose own warp, VectorCraft's, doesn't draw as its drawn art is tried again as a mesh envelope on the grid the file saves for it: its type stays editable and keeps the file's shape, but the warp's settings (style, bend) are lost, as the document has no place for them on a mesh. Type with strokes in an envelope with Distort Appearance on is also tried mapped from its glyphs grown by as far as its strokes paint along a side (half the weight of a centred stroke), without what miter joins add at corners, where the size the file saves for it doesn't already give that box; the drawn-art check decides which one opens. An envelope's grid reads its way round from all its rows and columns, so a mesh bent far round reads the way it runs. While an envelope's contents are edited, its mesh is kept in its dictionary, and in some files that mesh lies away from the drawn art by a move, the contents with the drawn art (as if the mesh hadn't followed the envelope when it moved): a mesh or top object saved in Edit Contents whose mesh draws the contents as large as the drawn art but elsewhere is tried again, after every other way, with its mesh moved onto that art, and opens there where it then draws as it.
     In a `.ai` opened from its editing data, Convert to Shape on a whole path or type object opens as a live Rectangle, Rounded Rectangle or Ellipse effect with its Absolute or Relative size, its corner radius, its place among the object's effects and whether it is hidden. A relative size in the file is added to each side. A relative Ellipse, or a setting VectorCraft doesn't read, keeps the drawn art (`crates/eps/src/import/ai/style/tests.rs`, `crates/eps/src/import/ai/tests.rs`, `crates/eps/src/import/tests_native.rs`).
     In a `.ai` opened from its editing data, Bas Relief in an art style takes its Detail, Smoothness and Light direction from the style's settings block, and an object other than type with it opens as itself with the live effect. A settings block that VectorCraft can't read (malformed, another effect's, a value out of range or a key it doesn't know) keeps the object's drawn look (part of #637; [raster effects reference](https://helpx.adobe.com/illustrator/desktop/special-effects-styles/apply-filter-effects/raster-effects-reference.html), [Photoshop File Formats Specification](https://www.adobe.com/devnet-apps/photoshop/fileformatashtml/), [scripting the filter gallery](https://community.adobe.com/questions-712/scripting-support-for-the-filter-gallery-1064646); `crates/eps/src/import/ai/style/tests.rs`, `crates/eps/src/import/ai/tests.rs`).

The Save PDF dialog's "Write pages longer than 200 in at full size in points" (`longPagesInPoints`, off by default) writes such pages in points without a `UserUnit` at every PDF version.
     PDF export warns when a PDF/X file has no bleed on a side where the document's bleed has one, and writes the file as asked.
     PDF/X-1a, PDF/X-3 and PDF 1.3 files keep the art under the hidden part of a picture, gradient, pattern, mesh or raster effect that a clipping mask or clipping layer crops: flattening rasterizes only the part of such art that its clipping path shows, on its own page and on the next one. Layers the file leaves out are left out of the flattening, and transparent art that a clipping path hides entirely is removed (`crates/engine/src/cmd/fileio/tests_pdfx.rs`).
     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, at its path, or in the folder the editing data names relative to the document's, such as `src/`, is read as the document opens, and its link takes that file's size, modification time and hash). 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).
