- use average instead of min/max for fine offset and gain
- rewrite supported resolution list as x and y arrays
- merge x and y resolution options into single option
- move scan params into two new structs, s->u and s->s
- sane_get_parameters() just returns values from s->u
- dont call wait_scanner() in object_position()
- dont call ssm_*() from option handler
- refactor sane_start()
- read_from_buffer() can workaround missing res, modes and cropping
- set most DR-2xxx machines to use the read_from_buffer workarounds
- set default threshold to 90
- add option for button #3 of some machines
- don't eject paper during init
- add DR-2010 quirks
- switch counter to HARD_SELECT, not SOFT
- fix DR-2510C duplex deinterlacing code
- rewrite sane_read helpers to read until EOF
- update sane_start for scanners that dont use object_position
- dont call sanei_usb_clear_halt() if device is not open
- increase default buffer size to 4 megs
- set buffermode on by default
- hide modes and resolutions that DR-2510C lies about
- read_panel() logs front-end access to sensors instead of timing
- rewrite do_usb_cmd() to use remainder from RS info
* doc/desciptions/canon_dr.desc: backend v24, update DR-2510C comment
- improved macros for inquiry and set window
- shorten inquiry vpd length to match windows driver
- remove status-length config option
- add padded-read config option
- rewrite do_usb_cmd to pad reads and calloc/copy buffers
* backend/canon_dr.conf.in: s/status-length/padded-read/g
- add byte-oriented duplex interlace code
- add RRGGBB color interlace code
- add basic support for DR-2580C, DR-2050C, DR-2080C, DR-2510C
- add more unknown setwindow bits
- add support for 16 byte status packets
- clean do_usb_cmd error handling (call reset more often)
- set status packet size from config file
- rewrite config file parsing to reset options after each scanner
- add config options for vendor, model, version
- dont call inquiry if those 3 options are set
- remove default config file from code
- add initial gray deinterlacing code for DR-2510C
- rename do_usb_reset to do_usb_clear
* doc/descriptions/canon_dr.desc: backend v18, update model status
* backend/canon_dr.conf.in: added better comments and new options
- add all documented request sense codes to sense_handler()
- fix color jpeg (remove unneeded BGR to RGB swapping code)
- add macros for LUT data
* backend/canon_dr.conf.in: add DR-2080C usb ID
* doc/descriptions/canon_dr.desc: backend v10, add DR 3020
