+ 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).
