I would expect that for scientific graphics this is, in at least some
sense, a very good thing, because what cairo is doing amounts to drawing
the line closer to its true location. Two values that differ by less
than a pixel will actually look slightly different instead of getting
hammered into the same pixel row. For graphing, this is a big win, at
least for me.
