Summary [Win] Use tiled drawing for main background layer

Reported 2015-09-18 10:17:44 PDT
When compositing layers are used on Windows, a single large layer is created for the root of the rendering tree. If the markup involves creating large offscreen areas, WebKit can end up allocating a lot of memory. Instead, we should use the tiled drawing logic for the background layer so that we can limit the amount of memory used.
