Description Botond Ballo [:botond] 2013-07-19 08:07:07 PDT
When content does a scrollTo(), if a pan/zoom animation is in progress it should be cancelled. On Fennec+APZC, this means hooking up NativePanZoomController.abortAnimation() to call AsyncPanZoomController::CancelAnimation.

The attached patch hooks up NativePanZoomController.cancelAnimation(). It also fixes a bug in AsyncPanZoomController::CancelAnimation() where it was modiying the mState field which is supposed to be protected by the monitor, but neither it nor its caller was grabbing the monitor.

Move this down so that it's in the same block as the other public native void functions.

Use a four-space indent throughout this function. That seems to be what the majority of code in this file uses.
