Currently the raster cache has a first-come first-served limit to the number of pictures it can cache in a frame. For particularly complex pictures like SVGs, this could lead to hard to diagnose performance issues on a per-frame basis, as other pictures that may be prerolled first may cause it to be surprisingly evicted
