.ai import: type keeps its own opacity and blend mode

A .ai or EPS opened from its editing data lost the opacity and blend
mode of its text objects. text_slot made the slot without the graphics
state's opacity and blend mode, which paths, meshes and images take, so
an Xy before a text object was lost. An Xy after it reached the slot,
but fill_slots then put type made from the text document in the slot's
place with only its visibility and name, and style_marker dropped the
transparency that a text object with an appearance carries on its look.

text_slot now takes the state's opacity and blend mode. fill_slots
gives made type the slot's opacity, blend mode, isolation and knockout.
The page's type gets them too, in place of its own transparency when
that is none, the slot's, or the slot's combined with that of the
objects around it; otherwise the page's type and the strokes around it
keep their own (a fill's, for example). When the type has transparency
and comes with other art (the strokes the page draws around it, or page
type that goes with it), a group of them takes the transparency. A text
object with an appearance takes the transparency from its look; where
the look draws more than the type and has transparency, the look and
the type go into a group that has it, and that group is not taken as
the look of a later object. The import fuzz's .ai tokens now include a
commented text object, 1 /FreeUndo , and a group's state marker
(6 () XW).

CMYK images keep their ink amounts from PDF import (and from placed CMYK TIFFs and the images in an `.ai` or EPS file's editing data, an alpha channel coming in as a grayscale opacity mask) to PDF export: a CMYK JPEG passes through unchanged, others stay CMYK (DeviceCMYK, or ICC-based CMYK in PDF/X-3/X-4) unless the Output settings convert them; the canvas shows them through the working CMYK profile (#320). Overprint is kept from PDF import (opened, the PDF part of an `.ai`, placed) to PDF export: the graphics state's `/OP` and `/op` become the overprint of fills, strokes and type, so a spot colour over a process colour still overprints; a page whose overprint can't be read for certain knocks out with a note, as does `/OPM 0` being read as nonzero overprint (#1388; hand-written fixtures, `pdf/src/tests_import_overprint.rs`). A masked CMYK image (`/SMask`, `/Mask` or a colour key) keeps its inks too, its alpha coming in as a greyscale opacity mask.
     SVG import's style cascade, used for hidden objects, non-scaling strokes and type, tests each element only against the `<style>` rules for its id, its classes and its element name, and the rules whose selector ends in none of these (`*`, `[x]`).
     A `.svgz` file copied in a file manager pastes as its art, as a copied `.svg` file does.
+    In a `.ai` or EPS opened from its editing data, type has its text object's opacity and blend mode, whether it is made from the file's text document or taken from the page. Where such type has transparency and comes in with other art (the rest of its look, or page type and strokes that go with it), a group of them has it. Where the page draws its type, or the strokes around it, with transparency that is neither its text object's nor its text object's combined with that of the objects around it, the page's type and strokes keep their own instead (`crates/eps/src/import/tests_native.rs`).
     In SVG export without Fewer `<tspan>` Elements, each character of live type that justification or Mojikumi moves (the letter gaps of a Justify All line without word spaces, the gaps between the characters of a justified Japanese line, closed-up punctuation, the space between Japanese and Latin letters) starts its own positioned `<tspan>`, and type scaled horizontally on a justified line is stretched to its own width (`crates/svg/tests/text_layout.rs`).
     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`).
