* This class is intended to be used as:
* Get an SkSurfaceCharacterization representing the intended gpu-backed destination SkSurface
* Create one of these (an SkDeferredDisplayListRecorder) on the stack
* Get the canvas and render into it
* Snap off and hold on to an SkDeferredDisplayList
* Once your app actually needs the pixels, call SkSurface::draw(SkDeferredDisplayList*)
* This class never accesses the GPU but performs all the cpu work it can. It
* is thread-safe (i.e., one can break a scene into tiles and perform their cpu-side
* work in parallel ahead of time).
