 * PRenderFrame (in the layout sense of "frame") represents one web
 * "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.

     * Shadow layer trees can be grafted into the parent's in one of
     * two ways
     *  - direct shadow tree: updates are sent to parent
     *  - indirect: the parent holds a reference (ID) to a shadow tree
     *    that's managed by the compositor.  During composition, the
     *    shadow tree is looked up and grafted appropriately
     * |id| is set to 0 in the "direct" case, and to a whole number
     * in the "indirect" case.
