Comment (by strk):
Perturbating the input (such as rounding its coordinate values) is often
enough to change the outcome of operations. A good test would be computing
the intersection between two segments long 10 times the grid cell size,
crossing and having the endpoints at "scale" distance each other. If the
computation is performed at the target precision model the intersection
point will on the grid, otherwise it'll be in between.
