[webkit-dev] How to interrupt Webkit Dump Render Tree output

Thank you.

So to get absolute co-ordinates of each Render Object, I need to do
something like:

int absolute_x = 0;
int absolute_y = 0;

parent = renderObject.getParent()

while (parent != RenderBody) {
     absolute_x += parent.getX();
     absolute_y += parent.getY();


Is that right?

Thank you.
