Bug #313035 (size of TPU)

This problems was on epson 4990 too.

The problem is that the scanners has 2 size of TPU a big and a small.
On the 4990 the difference is infrared scanning which is only working on 
the small.

There is a solution now i en epson2 backend that gives you 2 TPU with 
different size. It is working for the epson 4990 (GT-X800) and for 
GT-X900, which should bee both v700 and v750 (I am not totally sure). I 
have only tested 4990 and I think there is no confirmed  test for the 
GT-X900 - has any one a v700 and v750 please test it, but remember to 
use the git version of sane, I don't think it is in any released version.

Best regards
