* backend/mustek.*: Update to Mustek backend 1.0-97. This is a
development version and is only tested for three-pass scanners.
Added support for Paragon 1200 SP Pro and ScanExpress A3 SP.
Removed detection of " C04" and " C12" (don't seem to exist).
Changed SCSI request scheme. Sane_read can read more than 4096
bytes from pipe. Minimum dpi is 30 now. Fixed LD correction for
Paragon 1200SP 1.06 and 1.11. Read SCSI buffer into big block and
do LD after that for Paragon one-pass scanners. New option
"blocksize" in mustek.conf. Better detection of the scanner type
(three-pass, Paragon I, ...). Fixed possible segmentation faults
in Paragon 600 II N LD code, scsi_sense_wait_ready and
sense_handler. Decreased maximum scan size of Paragon 800 II
SP. For three-pass scanners: fixed stop_scan and speed code, scan
area is in pixels now, added RGB brightness and contrast, use
+-100% for brightness and contrast. Return SANE_STATUS_CANCELLED
when scan was cancelled. Option "force backtracking" is enabled by
default, "scan speed" is set to "fastest". Added option
"force-warn" for mustek.conf. Rewrote halftone mode. Better error
handling and more debug output.
* TODO: Clarified point about image data polarity. Moved point about
xscanimage not updating the progress bar for 3pass scanners to
frontend section. Removed umax entry in "frontends". Removed entry
about alpha channel (was added to LEVEL2 file).
* LEVEL2: Add point about image data polarity.
* frontend/scanimage.c: Removed some warnings.
