settings. Calibration is not completely ok yet, however. Code cleanup for
setup_scan (only one function for all chipsets). Simplified line mode/pixel
mode setting Updated TODO. Mustek BearPaw 2448 TA Plus is now only "basic". Too
much trouble for "good". Removed option "fast preview". By default for preview
mode 8 bits/pixel are used. Fixed indentation. Full scan really scans from y=0
on gt6816 scanners now.
