image: replay the recording surface directly onto the target
백현기 reported a use-case where he was recording an entire web-page
onto the recording surface, in order to facilitate panning. In this
scenario, where there may be lots of similar surfaces within the
recording we generate thousands of unused snapshot-images bloating
memory usage and impairing performance.
Under the right conditions we can replay directly onto the destination
which not only bypasses the snapshots but also skips the following
resampling.
