             up a spatial hierarchy (currently an R-Tree), plus a tree of Canvas'
             usually stack-based clip/etc state. This requires an increase in
             recording time (often ~2x; likely more for very complex pictures),
             but allows us to perform much faster culling at playback time, and
             completely avoid some unnecessary clips and other operations. This
             is ideal for tiled rendering, or any other situation where you're
             drawing a fraction of a large scene into a smaller viewport.
 
             In most cases the record cost is offset by the playback improvement
             after a frame or two of tiled rendering (and complex pictures that
             induce the worst record times will generally get the largest
             speedups at playback time).
 
             Note: Currently this is not serializable, the bounding data will be
             discarded if you serialize into a stream and then deserialize.
