Comment (by strk):

 Kind of snaptogrid is what you get when floating precision
 operation can't complete due to some robustness issue
 (lines almost parallel that intersect, usually).

 Even if the problem occurs on a very small portion of the
 geometry, precision reduction is applied to the whole geometry,
 incrementally, until the operation succeeds.
