[Gmsh] Saving a CustomMin = 0

[Marc Duflot]

Hello.

I just want to report a small bug.

If I set the range type of a view to 'Custom', the CustomMin to 0 and 
the CustomMax to a positive value, the CustomMin is not saved in the 
.opt file because it is equal to the default value. But, when I re-open 
my .pos file with the option file, the Min is set to the minimum value 
of the view.

An easy fix is ta save all the options or to set CustomMin to 1e-42 but 
that's not clean.

Thanks.
Marc.
