I propose to add the option to enable deferred canvas in bench, in this way we

One small comment, otherwise LGTM

File bench/benchmain.cpp (right):

http://codereview.appspot.com/6013051/diff/1/bench/benchmain.cpp#newcode467
bench/benchmain.cpp:467: log_error("missing arg for -forDeferred\n");
forDeferred -> forceDeferred ?
