1. It looks like truncated area is only at preview (which is scanned at

2. This scanner (at least my model) have scanning area height 300mm, but
   in driver code MAX_Y_S is 330 mm, and setting br-y to 330mm makes that
   whole area is scanned, but then there is something wrong with colors;
   (see: http://strony.aster.pl/kjonca/debug-297.jpg, warning, 16MB
   when I changed (just for testing):
   #define MAX_Y_S 297
whole area is scanned, but colors and preview are still wrong. 
Any ideas?
