Summary
Paddings are rounded to whole pixels

Test with Chrome that has SUBPIXEL_LAYOUT enabled. While testing for
bug 90097
, I came across this bug: According to
https://trac.webkit.org/wiki/LayoutUnit
paddings are supposed to have subpixel precision, but this sample shows that they are being rounded:
http://jsfiddle.net/behdad/ALd5F/5/
Output: span[position:static; padding-right:7.5px]: rect.width=7 span[position:fixed; padding-right:7.5px]: rect.width=7 span[position:absolute; padding-right:7.5px]: rect.width=7 span[position:relative; padding-right:7.5px]: rect.width=7 Applying patches in
bug 90097
fixes the two middle cases, but no the other two: span[position:static; padding-right:7.5px]: rect.width=7 span[position:fixed; padding-right:7.5px]: rect.width=7.5 span[position:absolute; padding-right:7.5px]: rect.width=7.5 span[position:relative; padding-right:7.5px]: rect.width=7

Thanks!
