Start drawing immediately 

We used to have a condition to start drawing only in the second traversal,
which added a delay of about 10-15ms. We believe that we don't need this
anymore, because we have other means of synchronizing the app transition
animation with the app drawing - we wait for all surfaces to be drawn
in window manager.
