     208== [#=View the debug border & repaint count] ==
     209You can see the debug visuals when setting WEBKIT_SHOW_COMPOSITING_DEBUG_VISUALS environment value to 1 as follows.

    208213== [#=CSSAnimations CSS Animation Support] ==
    209214Currently, in WebKit2, CSS animation frames are handled together with all other frames – the web process re-layouts for each frame, and sends the new transform/opacity/filter information together with the rest of the frame. The requestAnimationFrame feature, which allows synchronizing animations with the display refresh, is synchronized with CoordinatedLayerTreeHost to make sure those animation frames are interpolated as accurately and smoothly as possible, avoiding choppiness and throttling.
