Patch by Kentaro Hara <haraken@google.com> on 2011-08-03
Reviewed by Darin Fisher.

Implemented EventSender.scalePageBy(f, x, y), which scales a page by a factor of f
and then sets a scroll position to (x, y). Enabled the tests that had been waiting
for the implementation of EventSender.scalePageBy(f, x, y).
