rewrite init_vpd for scanners which fail to report overscan correctly
update description and man page to match
rebuild po files with updated line numbers
- remove ipc_mode option and variables
- set ipc mode based on other options
- cleanup inverted logic DTC options
- fixes threshold option reported in #315069
- hide compression-arg option when jpeg disabled
- add Send/SC/GHS macros for recent scanners
- add initial support for fi-74x0
- add initial support for fi-7030
- set has_MS_lamp=0 for fi-71x0
- add I18N macros to all option titles and descriptions
- add usb ids for many newer scanners
- br_x and br_y locked to page_width/height until changed
- add USB ID's for fi-6xxxLA and fi-6xxxZLA scanners
- add USB ID's for unsupported SP11xx scanners (genesys based)
- call get_pixelsize after start_scan, not before
- extend get_pixelsize to request backside data
- stop using backup/restore_params
- don't use extended get_pixelsize on M3091 or M3092
- call software crop code on backside images too
- support fi-7160, fi-7260, fi-7180 and fi-7280
- remove unused var from do_scsi_cmd()
- added more request_sense options
- add adv_paper_protect option
- enable paper protection by default
- increase max_x_fb for fi-6240 and fi-6230
default buffer-mode to off
improved error handling in sane_start
image width must be multiple of 8 when swcrop is used before binarization (iX500)
check hopper sensor before calling object_position(load) on iX500
- separate s->mode into s_mode and u_mode
- separate s->params into s_params and u_params
- generate grayscale and binary in software if required (iX500)
- support for ScanSnap iX500
- fix bug with jpeg de-interlacing code
- allow has_MS_* and has_pixelsize to be set in init_model
- fix use of uninitialized buffer in send_lut
- add send_q_table()
- allow wait_scanner() to be bypassed in object_position
- moved send_lut() to after set_window
- correct max_y_fb for fi-62x0 series
- add must_fully_buffer helper routine
- add hwdeskewcrop option, with fallback to software versions
- add 'actual' param to get_pixelsize for post-scan
- add recent model VPD params
- only set params->lines = -1 when using ald without buffering
- fix bugs in background color when using software deskew
- M3091 does not support scanner_control(adf)
- Correct buffer overflow in read_from_3091duplex()
- sane_read() now always calls read_from_*()
- read_from_*() are callable when there is no data, and read to eof
- sane_read() will keep alternate duplex reads to similar length
- Added debugging statements
- Corrected comments
- Updated Copyright
- merged x/y resolution options
- moved page width/height to start of geometry group
- use mode to pick resolution list v/s range
- improved M3091 resolution choices
- backup and restore image params around image processing code
- cache software crop/deskew parameters for use on backside of duplex
- fi-6110 does not support bgcolor or prepick
- store more Request Sense data in scanner struct
- clear Request Sense data at start of every do_cmd() call
- track per-side ILI and global EOM flags
- set per-side EOF flag if ILI and EOM are set
- sense_handler(): collect rs_info for any ILI, not just EOM
- do_usb_cmd(): use rs_info whenever set, not just EOF
- read_from_*(): better handling of EOF from lower level functions
- sane_read(): improve duplexing logic
