[sane-devel] Support for CanoScan 9000F and others: Modify dpi_list

[Rolf Bensch]

Hello,

Some scanners supported from the PIXMA driver have different dpi 
capabilities for flatbed and ADF/TPU modes:

e.g. CS9000F supports 75-4800 dpi in flatbed mode and 300-9600 dpi in 
TPU mode.

There are two new parameters in pixma_config_t: ext_min_dpi and 
ext_max_dpi to configure different dpi settings for ADF/TPU mode vs. 
normal (flatbed) mode. Normally there are no scanners with ADF and TPU 
on one device, so this can be handled with the same parameters.

Following scanners are affected:

Canon PIXMA MG8100
Canon PIXMA MG8200
Canon PIXMA MP800
Canon PIXMA MP800R
Canon PIXMA MP810
Canon PIXMA MP830
Canon PIXMA MP960
Canon PIXMA MP970
Canon PIXMA MP980 Series
Canon PIXMA MP990 Series
Canoscan 8800F
Canoscan 9000F

This is available in git now or in the next daily git snapshot.

Cheers,
Rolf
