TODO: Remove this ugly hack (Protect). Read to learn why!
NOTE: I hate the Fixed Sane type. This type gave me a terrible
headache and a difficult bug to find out. The xscanimage frontend
was looping and segfaulting all the time with random order. The
problem was the following:
* You select new let's say BR_X
* sane_control_option returns info inexact (always for BR_X) but
does not modify val because it fits under the constrained
quantization.
Hm... Well sane_control doesn't change the (double) value of val
but the Fixed interpatation may have been change (by 1 or something
small).
So now we should protect the val if the change is smaller than the
quantization step or better under the SANE_[UN]FIX accuracy.
Looks like for two distinct val (Fixed) values we get the same
double. How come ?
This hack fixed the looping situtation. Unfortunately SIGSEGV
remains when you touch the slice bars (thouhg not all the
time). But it's OK if you select scan_area from the preview window
(cool).
