.ai import: a placed file on %_ lines no longer drops the layers

Browse Source 
A placed (linked) file written as an object's editable copy, on %_
lines after its drawn look, has its %AI5_BeginPlace and %AI5_EndPlace
markers on those lines too. The lexer dropped comments after %_ that
don't start a section, so the placed file never began, the ~ that ends
it was an operator the reader didn't know, and the whole file came in
as its PDF part. The lexer now returns those two markers from %_ lines,
and the preview reader skips the %_ its header line starts with.

| Date | Change | Summary |
|---|---|---|
| 2026-10-30 | minor | `.ai` import: a placed (linked) file written as an object's copy on `%_` lines is read: its `%AI5_BeginPlace` and `%AI5_EndPlace` markers there were dropped, so the `~` that ends it was an unknown operator and the whole file came in as its PDF part; its preview's header, on a `%_` line too, is read. Own-fixture test in `import::ai::tests`; scores unchanged |
| 2026-10-30 | minor | PDF export: an opaque gradient mesh is written as one PDF Type 6 (Coons patch) shading (ISO 32000-1, 8.7.4.5.7) filling its outline, so viewers blend its colours smoothly instead of showing the bands and seams of the 8 × 8 flat quads a patch it was cut into; a file of 65,558 small meshes exports in 14 s instead of 56 s, at half the size. A mesh with see-through points is still written as quads. Own-fixture tests in `tests::mesh_export`; scores unchanged |
| 2026-10-30 | minor | `.ai` import: a file whose PDF part is an empty page opens from its editing data where that reads, instead of opening blank; scores unchanged |
| 2026-10-30 | minor | `.ai` import: a file whose PDF part's pages are cropped to its art rather than its artboards no longer comes in as that PDF part (each page a copy of all the art) but from its layers, with its artboards, where they draw as the page does; own-fixture test in `tests_aiimport`; scores unchanged |
