Thinking about this some more, I'm not sure it's as simple as I made it out to be. The parent flexible box could be at a non-integral position, and maybe the non-integral centering has a final result that puts the child at an integral position. Or perhaps the child has non-integral padding but the end result is that the text gets placed at an integral position.

In other words, attempting to snap without knowing the absolute offset is probably not correct. Painting does know the absolute offset, so it can get away with pixel snapping.

It may be that rounding during layout is still correct, but local rounding does seem a bit suspicious, since one could obviously design a page with non-integer values that would not need any rounding to occur for the text that you render. Local rounding would then make that page incorrect.
