I generally live by the rule that Global variables / functions are evil and that every piece of code should live in the class to which it pertains.
This is a very easy rule to follow, and I believe that I haven't ever run into an issue with this rule until now.
Today, however, I need to add a function to my assembly rather than to a specific class. That is, almost all of my classes could have a use for this particular function.
Where should I put this function (+1 overload)?
If I put it in a "Utilities" class, I feel dirty. If I tack it on to a semi-related class, and let other classes call it directly, I feel worse.
This particular piece of code basically chops a IList<PointF> into a normalized list. I feel right now that adding it as an extension method on IList<PointF> may be the best bet...
