    3131||tables||pixel||Using integers to ensure even distribution of available space across columns and to match specification.||
    3232||RenderLayers||subpixel||RenderLayers are positioned along with their renderer, and need to accumulate their offsets with subpixel precision.||
     33||GraphicsLayers||pixel||Graphics layers and their compositing remain unchanged.||
    3334||floats||subpixel||These are always blocks and we'd otherwise be incapable of having 2 floats on the same line, each at 50% width on a line with an odd width.||
    3435||widgets, plugins, video, and foreign objects||pixel, snapped||These are either rendered outside of WebCore, or pass through an intermediary embedding layer. We need to use integers so the contents are painted at whole-pixel values.||
