20020217_testtool

	general:
	* Added possibility to scan at half speed
	* Activated _ProbeRegisters function to dynamically check the
	  chipset's capabilities (instead of just relying on the USB id).
	* Update to make use of handles for device access
	  (instead of static structures)
	* Attempt to add NIASH00012/NIASH00013 support.
	* Updated niash.conf yo use libusb by default
	* Updated default case handling in Hp3300cXferInit
	* Readme.html updated to conform to W3C standard
	* Other minor documentation fixes

	niash backend:
	* Fixed bug that caused scanimage to report about too much returned data.
	* Fixed scanimage --help warning.
	* Updates to comply with tstbackend tests.
	* Added check on scan area: topleft should be smaller than bottom-right.

20020422_testtool

	general:
	* Fixed various small documentation issues
	* Made an attempt to make hp3300c_xfer compile against libieee1284 0.1.5
	
20020505_testtool

	general:
	* Split up and reorganised initialisation for separate niash chips
	* Improved backtracking behaviour for HP3300c
	* Added experimental 150 and 600 dpi support for HP3400c

20020608_testtool

	* Split off individual transfer methods (linux scanner
	  kernel module, libusb etc.) as suggested by Marcin Cieslak.
	* Implemented smarter initialisation of transport layer, that
	  tries out all available data transfer methods instead of just one.
	* Added sanei_usb transfer method
	* Scanner lamp is now no longer turned off in sane_close
	* default device file for scanner is now /dev/usb/scanner0
	* Added experimental Agfa Snapscan Touch support provided by Jean Goffinet.

20020717_testtool

	* Removed hp3400c.c (functionality is now integrated in hp3300c.c)
	* Updated ieee1284 support (still untested)
	* Fixed memory corruption bug in vertical color alignment handling.
	* Fixed Agfa Snapscan Touch color alignment (Jean Goffinet)
	* Fixed deinitialisation in testtool executable
	* Implemented more dynamic use of sanei_usb
	* patch-sane.sh now patches the configure file for libusb (Ricardo Martins)

20020727_testtool

	* Updated Agfa Snapscan Touch calibration to skip mirroring
	* Removed CreateCalib function (is specific for a particular HP3300c model)
	* Removed Diagnostic function (never worked anyway)
	* Simplified internal scan buffer / backtracking calculation
	* Added scanner lamp turnoff in sane_close again
	* A simple calibration is done just before every scan in the sane backend.
	  This also means no more cal.dat file is created in the working directory.

20020816_testtool

	* Calibration is now done at true 600 dpi.
	* Fixed bug with Agfa Snapscan Touch calibration (Jean Goffinet)
	* Prepared future implementation of separate gamma tables for R,G,B.

20020922_testtool

	* Implemented new data transfer methods interface.
	  This prepares easier reporting of the scanner type to the SANE layer.
	* Fixed bug for niash00019 scanners with vertical resolution.

20021015_testtool

	* Updated reporting of scanner type to upper layer. The SANE backend now
	  reports the actual devices present, with the correct scanner model.
	  This should even allow for more than one scanner at a time (untested).
	* Disabled linux scanner kernel and libusb access methods by default,
	  since they are handled by the sanei_usb access method in sane 1.0.9.
	* Updated patch script for use of sanei_usb
	* Fixed bug for niash00019 scanners related to vertical scanning limit

20021120_testtool

	* Updated uscanner driver for new data transfer method API (Marcin Cieslak)
	* Fixed registers in hp4300 blink test
	* Cleaned up README.html
	* Implemented fix for vertical offset problem of hp3400 and hp4300
	  (as suggested by Ullrich Sigwanz)
