[sane-devel] Epson 3590

[Oliver Schwartz]

Hi,

> I tried more resolutions. The results are funny:
> - 200 dpi is OK
> - 150 dpi works, too
> - 100 dpi works, but the scanned area was displaced in y direction
> -  75 dpi works, but scans a larger y distance than expected
> -  50 dpi is OK,
> - values under 50 are rounded to 50

I've added 150 and 50 DPI to the resolution list in CVS. I've also 
added some code to set the preview bit correctly for the 3490. The 
code is in CVS. Please test :-)
