-Add a --testing flag to sky_viewer and cause it to paint into an SkBitmap instead of a ganesh surface so we can get the pixels out. -Add GetPixelsForTesting to layer.cc to actually grab out the pixels. -Add a reftest and a mismatch reftest. They need a setTimeout after the load event. Unclear why or what the right fix is. Maybe we should give internals some way to force the paint? If we don't have the setTimeout, we paint a white page (so we do a paint, but with no content). -Add a DisplayDelegate to Layer so that Viewer can decide whether to use the real ganesh backend or the SkBitmap one without littering the whole code-base with is_testing bools and logic.
