We should remove this comment now.

[Erik Dahlström (inactive), 2013/11/29 16:30:48]

Done.

     // 16.4: "If there are no graphics elements whose relevant graphics content is under the pointer (i.e., there is no target element), the event is not dispatched."

Can you move this comment above "return false;"?

[Erik Dahlström (inactive), 2013/11/29 16:30:48]

Done.

Can you add an assert here that the object bounding box is valid?
ASSERT(isObjectBoundingBoxValid());

[Erik Dahlström (inactive), 2013/11/29 16:30:48]

Done.
