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

[Lucius Fox]

I load www.google.com in WebKit and Dump Render Tree output.

Here is the part of the output:
But I don't understand is the y co-coordinate output.

The 'Language Tools' y co-coordinate is 22. And the ' the web' y
co-coordinate is 2.
But visually, the text 'the web' is BELOW 'Language Tools', so why the
y co-coordinate is less than 22?

   RenderInline {A} at (0,0) size 76x11 [color=#0000CC]
                      RenderText {#text} at (6,22) size 76x11
                        text run at (6,22) width 76: "Language Tools"

RenderBlock {INPUT} at (245,3) size 12x13
                      RenderInline {LABEL} at (0,0) size 49x15
                        RenderText {#text} at (260,2) size 49x15
                          text run at (260,2) width 49: " the web"

Thank you for helping me understanding it
