WebKittens, We're planning to wrap up our conversion of the RenderTree to subpixel units next week. 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.
This will effect a large number of layout test expectations as well as some platform interfaces. If you are working on or maintaining a port other than Apple, Qt, and Chromium, please touch bases with us. Thanks! -Emil and Levi On Fri, Oct 28, 2011 at 1:43 PM, Levi Weintraub <[email protected]> wrote: > WebKittens, > > As you may know, Emil and I have been diligently working on getting > subpixel layout up and running in WebKit.
