#529: SimpleSnapRounder performs bogus noding

Comment(by strk):

 The problem here was with misuse. SimpleSnapRounder, as all snap-rounding
 noders using HotPixel class, can only work with a FIXED PrecisionModel.
 FLOATING precision models break HotPixel and thus all its users.

 Will leave this ticket open until HotPixel is equipped with a control to
 throw IllegalArgumentException on a 0 scale.
