Comment(by nicklas):

 But what to do in 2.0?

 Leave it as it is?

 I can open a wikipage to discuss what functions that need tolerance and
 how.

 Strk, your comment in #1613 about how the floating point grid looks on
 different distance from origo in each projection is what it is all about I
 think and makes it quite complicated.
