document.export {format: "tiff"} writes baseline TIFF through the raster
export path (resolution, background, anti-aliasing, artboard ranges):
colorModel rgb (transparency as unassociated alpha), cmyk (ink amounts,
CMYK colours keep their inks) or gray, lzw (weezl), byteOrder little (II)
or big (MM), embedIcc, and the resolution tags. Export As offers it with
the tiffOptions dialog; TIFF moves from read-only to read and write.
The TIFF writer is shared: EPS previews now use it (and its PackBits)
instead of their own copy, so eps depends on render (layers allow it).

document.export {format: "jpg"} takes colorModel (rgb|cmyk|gray), quality 0–100, method
(baseline|optimized|progressive), scans (3–5), embedIcc and imageMap (none|client|server).
JPEGs are written with jpeg-encoder. CMYK files hold ink amounts drawn as the renderer's ink
planes, so CMYK colours keep their inks (black type stays black ink alone). Profiles are made
in code from the CMS (cms::icc_bytes): the RGB spaces from their primaries, the CMYK spaces as
Lab lookup tables sampled from their model, a grey with sRGB's tone curve, and loaded
profiles as loaded. Image maps write <stem>.html or <stem>.map beside the image for objects
with a URL and an Image Map shape. The JPEG Options dialog gains Color Model, Quality 0–10,
Method and Scans, Image Map and Embed ICC Profile; CMYK documents default to CMYK.
