[webkit-dev] Question about return values of RenderObject:localToAbsolute()

[Lucius Fox]

Hi,

I use the dumpRenderTree to dump out the absolute co-ordinates of the
Render Tree of www.google.com. I put the absolute x, y result at the
end marked by "{" and "}".
And www.google.com, the first text is 'Web" followed by "Images"
followed by "Video" followed by "Maps".

But what I don't understand is (from the output below), all the
absolute coordinates of those text are x = 8.0 and y = 3.0.  But
visually, they are next to each other horizontally. So the y values
should be the same but the x values should be different.  Can someone
please help me understand the result?

Thank you.

Here is the output:

RenderInline {B} at (0,0) size 27x15 {8.00,3.00}
            RenderText {#text} at (0,1) size 27x15 {8.00,3.00}
