This, once it is integrated with async scrolling (APZC) would let us rasterize new content during content without accessing the main-thread. We could build a layer tree for the entire page, but only rasterize content that falls within the prerendered viewport. When async scrolling attempts to scroll outside of the prerendered area, we would notify the painting thread of the new desired prerendered area and rasterize it. | ||
