[sane-devel] Lexmark backend / Dell A920

[Stéphane VOLTZ]

	Hello,

	I have done the planned changes in cvs/experimental/lexmark directory. The 
Dell A920 is partially supported since only 75 dpi color scans are working. 
Other modes will follow soon. Although I checked that the registers written 
are unchanged for the X1100, there may be bugs, since I don't have such a 
scanner to test.

	Next on my todo list is to add software shading correction, since this 
scanner doesn't have hardware calibration.

Regards,
	Stef
