Raster into an SkPicture before rendering a DisplayList.
Rasterizing a display list is more than 2x slower than rasterizing in the existing architecture. This is due to recording more with a display list and we have no bounding hierarchy to cull content quickly.
We can address this by creating an SkPicture from the list, with a bounding hierarchy, and rasterizing that instead. The result is slightly faster than the non-S.P. pipeline but uses 2x more memory.
