// TODO: The long-term for the public API around surfaces and flushing/submitting will likely
// be replaced with explicit control over Recorders and submitting Recordings to the Context
// directly. For now, internal tools often rely on surface/canvas flushing to control what's
// being timed (nanobench or viewer's stats layer), so we flush any pending draws to a DrawPass.
// While this won't measure actual conversion of the task list to backend command buffers, that
// should be fairly negligible since most of the work is handled in DrawPass::Make().
// Additionally flushing pending work here ensures we don't batch across or clear prior recorded
// work when looping in a benchmark, as the controlling code expects.
