---------------------
Fixed segfault in fine calibration for CIS devices.
Tweaked LiDE25 settings (thanks to Gerd Cendelin for lending me
his LiDE25).
Let 1200DPI CIS devices use now the green-channel for gray scans.
V 0.50-5 (2005-10-21)
---------------------
Fixed high-speed feature of CanoScan D660U.
V 0.50-4 (2005-10-02)

Stephan February <stephanf@singnet.com.sg> for providing these
values.
V 0.50-3 (2005-08-22)
---------------------
Fixed problem, when trying to scan at resolutions beyond the
optical one (sensor stops too early)
V 0.50-2 (2005-08-19)
---------------------
More cleanup.
Removed obsolete _WAF_BLACKFINE.
LiDE20 does not seem to have a reliable black calibration area,
so the devices now will switch off the lamp for dark calibration.
Fixed line statistics and added calibration data output.
V 0.50-1 (2005-08-15)
---------------------
Cleanup
Activated IPC between reader-process and parent
Added button support for Plustek/Genius devices
Did some whitespace cleanup and removed those *p typedefs
Tried to improve CIS calibration (somewhat back to 1.0.13)
Added _TWEAK_GAIN definition to allow CIS calibration increase
gain values during basic lamp setup phase
Added call to speedtest to CIS calibration
Fixed CanoScan startup problem (the way misc I/Os will be set
after power-up has done the trick)
V 0.49-8 (2005-08-08)
---------------------
Added LiDE25 settings
V 0.49-7 (2005-07-21)
---------------------
Bugfix release - fixed lampsettings for CIS calibration
V 0.49-6 (2005-07-07)
---------------------
Bugfix release - calibration and segfault :(
V 0.49-5 (2005-07-04)
