RoboHornetPro spends ~25% of total test time in WebCore::Region::Shape methods

RoboHornetPro supposedly adds some animation tests to the suite.  I've not yet investigated all the changes from RoboHornet.

Running Time    Self        Symbol Name

The 4th top symbol is also Shape related:

These come from layer updates:
