PDF export: Add Around is clamped when a file opens, and art too large for f64 gets no effect image

Browse Source 
document.rasterEffectsSettings accepts addAround from 0 to 1,000 pt,
but a file's raster_effects.addAround opened as it was saved. With
addAround 1e300, the area of a raster effect image overflowed f64,
the image scale became 0 and the image got the transform
[inf, NaN, NaN, inf, x, y]. PDF export left that image out, so the
drop shadow was missing.

A file's addAround now opens clamped to 0 to 1,000 pt. An effect
image whose area or scale is not finite is not made. Export then
keeps the object with its effects, and Expand Appearance expands it
without an image, as when its PNG can't be encoded.

Docs: docs/mcp.md (addAround).

`document.rasterEffectsSettings` holds how raster effects (shadows, glows, blurs, feathers) become images when PDF
export or Expand Appearance renders them: `resolution` (ppi, also New Document's `rasterEffectsPpi`), `colorModel`
(the document's `rgb`/`cmyk`, `grayscale` or `bitmap`), `background` (`white` makes the images opaque), `antiAlias`
(off: hard edges), `clippingMask` (the white stays under the art only), `addAround` (points of room around the art)
and `preserveSpotColors` (stored). They are also the defaults of `object.rasterize`, whose params override them (its
(off: hard edges), `clippingMask` (the white stays under the art only), `addAround` (0 to 1,000 points of room
around the art; a file's value outside that range opens as the nearer end) and `preserveSpotColors` (stored). They are
also the defaults of `object.rasterize`, whose params override them (its
`clippingMask` puts the image in a clip group with the art's outline). No params reports them; any of them changes them
in one undo step. PDF export renders the raster effects of every kind of object this way (paths, groups, layers, type,
images, symbol instances, live objects, and those in opacity masks, symbols and pattern tiles): shadows and outer glows
