* M3: glass effects take variables, and their frost stays within 0–100 (#1885)
Glass's light angle, intensity, refraction, depth, dispersion, frost and
splay bind to number variables, on a layer (`variable.bind`,
`effects/<i>/<field>`, `radius` being the frost) and in an effect style
(`style.bind`), and the Design panel's glass fields take a variable like
the shadow and blur fields. A variable reads as the field shows it:
intensity, refraction, dispersion and splay in percent.
A glass's frost stays within 0–100, the reference tool's range: a larger
frost from an older file draws at 100, and the field, a bound variable and
scaling stop there.

* M3: a frost from an older file scales and shows as it draws (#1885)
Review follow-up: a frost saved past 100 draws at 100, so scaling a layer
starts from that (150 halved draws at 50, not 75) and the Design panel's
Frost field shows it. The revision row's binding path escapes its pipes, so
the table keeps three columns.

* M3: Dev Mode and .fig export show a frost from an older file as it draws (#1885)
A frost saved before the 0–100 range draws at 100, and the canvas, CSS and
scaling already read it that way, but Dev Mode's Glass row and the .fig
export still read the stored number, so they said 150 where the canvas
shows 100. Both now read the sanitized frost.

node.set refuses unknown properties, but the effects inside it were read
by serde, which drops keys it doesn't know. A drop shadow given
offsetX/offsetY (the names variable bindings use for its offset) was
stored with the default offset [0, 4] and the call said ok. effect.add
and effect.set dropped them the same way.
The three now refuse what the effect doesn't read and say what it
takes: "effects[0]: unknown properties: offsetX, offsetY (a dropShadow
takes blend, color, offset, radius, showBehind, spread, type, visible)".
A key counts as read when setting it to null makes the effect fail to
parse or come out different, so serde's aliases count as read without a
list of them here.

- Background blur sees the whole backdrop under the layer: the renderer keeps the stack of
isolated surfaces it draws into (clipping frames, rounded clips, faded groups, masks) and
flattens it for the layer's area, reading past the layer's own box. A blur inside a clipping
frame now shows the frame's fill instead of the sharp layers below, on the canvas and in PNG
exports. The PDF export draws background blur and glass through the same code from a render of
what lies under the node (`backdrop::render_beneath`, which the PDF's backdrop now shares), and
its images match the PNG's pixels.
- Shadow spread offsets the outline: the shape filled and stroked twice the spread wide with
mitred joins (grow) or cut away (shrink), the stroked bands cached per outline. Ellipses stay
ellipses, stars keep sharp points, text keeps its letterforms, rounded corners grow their
radius. Inner shadows shrink the outline the same way. Canvas, PNG and PDF share the shadow
code; SVG writes spread shadows as the same geometry and now exports inner shadows.
- Glass effect (light angle and intensity, refraction, depth, dispersion, frost, splay): the
frosted backdrop bent towards the inside within `depth` of the edge, colour fringes, light on
the rim, from an exact distance transform with smoothed normals.
- Noise: mono, duo and multi colour modes, grain size, density, opacity and blend mode; grains
live in the layer's coordinates (stable when panning and zooming). Texture is now drawn
(pixels scattered by the radius, grain size, clip to shape).
- Design panel rows for noise mode/colours/opacity, texture clip to shape and every glass value;
`effect.add` takes `glass`; REST import of NOISE, TEXTURE and GLASS; Inspect rows and CSS;
the scale tool scales grain sizes, texture radius, glass depth and frost.
- Tests in new modules: render backdrop/spread/grain tests, PDF backdrop tests, SVG, doc,
engine and REST effect tests.
