…rder and the profile
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).

…ped rows
document.export {format: "bmp"} writes BMP through the raster export path:
depth 1 (black and white), 4 or 8 (a palette by reduction and dither,
optionally RLE4/RLE8), 16 (5-5-5), 24 or 32 (with alpha, a version 4
header); colorModel rgb or gray; fileFormat windows or os2 (a core header);
flipRows writes top-down rows (a negative height). Impossible combinations
are refused as bad params. Export As offers it with the bmpOptions dialog,
which keeps its choices writable together; BMP moves from read-only to read
and write (tests that used .bmp as the unwritable format now use .dwg).

document.export {format: "tga"} writes uncompressed true-colour Targa files
through the raster export path (resolution, background, anti-aliasing,
artboard ranges): depth 16 (5-5-5 with a one-bit alpha), 24 (flattened on
white) or 32 (8-bit alpha), rows bottom-up, with the version 2 footer.
Export As offers it with the tgaOptions dialog (Depth).
