[Bug 658792] Re: Add scan options for text mode scan (lineart or grayscale)
There are many comments about what is "best" for OCR (which is assumed
to be the goal of text-mode scanning). Some points:
1. OCR is so terrible in linux, it's hardly worth bothering with OCR tuning
2. Even so, I've read various tips on best OCR scanning method: the majority now seem to say grayscale
3. disk is so cheap, and with the hope of future OCR that actually works, erring on the side of more information would be preferable (that is, 8 bit grayscale)
3b. i would also make the default resolutions higher which also future proofs for better OCR.
If anyone actually wants 1 bit line art, then this could/should be a
simple post-processing step if not an alternative option in simple-scan.

Add scan options for text mode scan (lineart or grayscale)

Bug description:
Changes in bug #521323 means that text scans are now done in 2 bit
grayscale. This was done to improve readability and some scanners
seemed to have a very poor lineart mode. It may be useful to have an
option to choose what mode text is scanned in (lineart, 2 bit
grayscale, 8 bit grayscale).
