 * "page".  It's used to graft content processes' layer trees into
 * chrome's rendering path.  The lifetime of a PRenderFrame is tied to
 * its PresShell in the child process.
 * The child process conceptually "owns" a PRenderFrame, because it
 * only makes sense wrt documents loaded by the child.
