We've created a the following wiki page to help explain the changes we are making: https://trac.webkit.org/wiki/LayoutUnit If you work on the rendering code, please take a look and talk to Emil and me if you have any questions.

That wiki page doesn't say anything about how sub-pixel units will be handled in the compositing layer tree. There is already some "round to pixel boundaries after scaling" code in GraphicsLayer*, so I'd like to see some consideration of this before you land.
