Hm, could we snapshot the canvas & flip asynchronously?

It seems like the sync flip path should be deprecated, if possible.

We could. For now this is done synchronously for simplicity.

The sync flip is still used in the video_decode_accelerator_unittest (Not sure
if there are other targets using this). We'll need to convert that first if we
want to get rid of the synchronous flips.

Yeah, I think we should get rid of both uses.
