[sane-devel] genesys backend

[Stéphane VOLTZ]

	Hello

	I got time to test, and have it work at 75 and 150 dpi. This let me time scan 
with both methods: got exactly the same time on my 850MHz Duron. Better, the 
old function produced a slight bakctracking at the beginning of the scan, 
with the new function, it's now gone. So I checked it in.
	600 dpi scan failed, so the new data reading function needs some fixes, but 
can be done later.

Regards,
	Stef
