Hi, webkit folks. As we've already notified, we are currently working on implementing Threaded Coordinated Graphics in WebKit2 Gtk+. https://bugs.webkit.org/show_bug.cgi?id=100341
But, to reuse existing Coordinated Graphics code, we have decided to implement Threaded Coordinated Graphics in WebKit1 Qt first. https://bugs.webkit.org/show_bug.cgi?id=102994 Then, we will apply Threaded Coordinated Graphics to WebKit1 Gtk+ and WebKit2 Gtk+. Our design document for implementing Threaded Coordinated Graphics in WebKit1 Qt is in the link below. https://docs.google.com/document/pub?id=1u1Oif9lDmVt_MkJLxaEYbTlOuZWVJcKrM1vAxAvFrZk Any comments/concerns are appreciated.
