Geometry effects reach objects that aren't paths through their outlines (vectorcraft_effects::
reshape: glyph outlines, evaluated live art, the symbol's art, an image clipped by its reshaped
frame), applied to the whole art as one piece; the renderer caches that art per object and
paints raster effects around it in the same filter layers paths use (shared Renderer::raster_fx,
also used per fill/stroke). Exports bake the reshaped art; SVG writes per-item filters; PDF
warns about raster effects on strokes as well as fills and objects.

New Document.page_isolate / page_knockout, set by
transparency.togglePageIsolatedBlending / togglePageKnockoutGroup {value?}
(one undo step each, saved with the document, reported by
transparency.info) and the Transparency panel menu's check items. The page
renders as an isolated group (top-level blend modes no longer blend with
what lies under the page) and/or a knockout group whose elements are the
layers (neutral layers pass their objects through). PDF and SVG wrap the
page content in an isolated group and write page knockout as soft masks.

Both writers now ask the shared stroke geometry how to write each stroke
(effects::stroke::for_writer): a plain stroke where that is exact, else the
canvas's filled outlines (arrowheads, width profiles, dashes fitted to corners,
dots with round or projecting caps), grouped under the stroke opacity when the
line and its heads overlap. Brushed strokes are written as their brush art.
Inside/outside alignment only applies to closed paths, so open paths export as
centred strokes. The PDF outside-stroke clip frame and the SVG outside mask now
cover the whole stroke reach (miter spikes, projecting caps). SVG stroke
gradients use the same paint box as the canvas. The svg crate docs no longer
claim arrowheads, profiles, brushes and effects are dropped.

New Node.knockout_shape (transparency.set / object.setProps knockoutShape,
reported by transparency.info). In a knockout group such an object knocks
out only as much as its opacity and mask let through (a 50% object knocks
out 50%); otherwise its full coverage knocks out. The renderer, PDF and
SVG masks honour it, and the panel's checkbox is now live.

Knockout Group is now Knockout {Neutral, Off, On} (old files' true loads as
On, false as Neutral). In a knockout group each child erases what the
children below it drew where it paints, then adds itself, so it composites
against the group's backdrop; neutral plain groups pass their children
through to the enclosing knockout group. transparency.set / object.setProps
take knockout "on"|"off"|"neutral"|bool; transparency.info reports the
state. PDF and SVG write knockout groups as nested soft masks with the same
look (PDF warns); the Transparency panel has a tri-state checkbox.

Clip groups clip by compound paths (with their holes), even-odd paths, text
outlines and groups (the union of their members) on screen, in raster
export, in SVG and in PDF alike, through one shared region:
Node::clip_outline (the model walk) and effects::clip_outline (text
outlined, several shapes united), cached per clipping path in the
renderer. Nothing to clip by hides the clipped art everywhere, and clicks
hit a clip group only inside its clipping region. Make Clipping Mask takes
a compound path or text object on top (it loses its paint) and Release
gives it back unchanged in kind.

Area type was written as one <tspan> per paragraph at the frame's top-left: SVG text never wraps,
so every SVG viewer (and VectorCraft's own import) showed each paragraph as a single line running
out of the frame. Centred and right-aligned area type also got text-anchor="middle"/"end" at the
frame's left edge, so it was centred on (or ended at) that edge instead of inside the frame.
The exporter now asks the text layout for the lines: each line is a <tspan x y> at its baseline,
at the line's left edge, centre or right edge to match the text-anchor, with hyphenated breaks
written with their hyphen and the spaces at soft breaks dropped. The <text> carries the first
line's position too, so importers that place text by its own x/y (ours included) start at the
first line. Re-importing an exported file now reproduces the area type pixel for pixel as point
type with the same line breaks (justified lines lose their extra word spacing).

A dash pattern with a negative value (for example [-5, 3], from `stroke.set` or a PDF `d`
operator) was handed to the dasher whenever any value was positive. When the values sum to zero
or less the dasher never advances, so rendering the document hung forever (canvas, screenshot,
PNG/JPEG export, `vectorcraft-cli convert`).
PDF (32000-1 §8.4.3.6) and SVG (`stroke-dasharray`) both define such a pattern as invalid and the
stroke as solid. `Dash::is_dashed` now says whether a pattern draws dashes (finite, non-negative,
not all zero), and the renderer, the width-profile outline, the SVG and PDF exporters and the PDF
importer use it, so an invalid pattern is drawn, written and read back as a solid stroke everywhere
(the PDF exporter used to clamp negatives to 0, writing zero-length dashes).
