This CL sets the stage for retracting the SkPicture::kOptimizeForClippedPlayback_RecordingFlag flag
from the public API (more work needs to be done in Blink & Chrome). In the new world the only way
to set this flag (and thus instantiate an SkPicture-derived
class) is by passing a factory to the SkPictureRecorder class. This is to get all clients always using
factories so that we can then change the factory call used (i.e., so the factory just creates a BBH) and
do away with the SkPicture-derived classes.
