 Sky's Run Loop
 ==============
 
 Sky's run loop consists of running the following, at 120Hz (each loop
 takes 8.333ms):
 
 1. Send scroll and resize events if necessary, limiting each handler
    to 1ms, and limiting the total time spent on these handlers to 1ms.
 
 2. Fire animation frame callbacks for up to 1ms. Each callback can run
    for up to 1ms. Once 1ms has expired, throw a (catchable)
    EDeadlineExceeded exception. If it's not caught, drop subsequent
    callbacks.
 
-3. Spend up to 1ms to update the render tree, including calling
+4. Spend up to 1ms to update the render tree, including calling
    childAdded(), childRemoved(), and getLayoutManager() as needed.
    Once 1ms has expired, throw a (catchable) EDeadlineExceeded
    exception, leaving the render tree in whatever state it has
    reached.
 
-4. Update as much of layout as possible; after 1ms, throw a
+3. Update the ElementStyleDeclarationList objects for all elements on
+   the RenderTree.
+
+5. Update as much of layout as possible; after 1ms, throw a
    (catchable) EDeadlineExceeded exception, leaving the remaining
    nodes unprepared.
 
-5. Update as much of paint as possible; after 1ms, throw a (catchable)
+6. Update as much of paint as possible; after 1ms, throw a (catchable)
    EDeadlineExceeded exception, leaving any remaining nodes
    unprepared.
 
-6. Send frame to GPU.
+7. Send frame to GPU.
 
-7. Run pending tasks until the 8.333ms expires. Each task may only run
+8. Run pending tasks until the 8.333ms expires. Each task may only run
    for at most 1ms, after 1ms they get a (catchable) EDeadlineExceeded
    exception. While there are no pending tasks, sleep.
    Tasks are things like:
     - timers
     - updating the DOM in response to parsing
     - input events
     - mojo callbacks
 
 TODO(ianh): Update the timings above to have some relationship to
 reality.
 
 TODO(ianh): Define an API so that the application can adjust the
 budgets.
 
 TODO(ianh): Define how scroll notifications get sent, or decide to
 drop them entirely from this model.
