 // Unfortunately, using full precision floating point here causes bad layouts
 // because floating point math isn't associative. If we add and subtract
 // padding, for example, we'll get different values when we estimate sizes and
 // when we actually compute layout because the operations will end up associated
 // differently. To work around this problem for now, we round fractional pixel
 // values up to the nearest whole pixel value. The right long-term fix is to do
 // layout using fixed precision arithmetic.
