 The DPI should be changed for the screen in use.  At least in the XO
 device, it should be changed to 134.

 What we used to set in hulahop: http://kb.mozillazine.org/Layout.css.dpi

 There is an attribute in webkitgtk+, device_dpi gobject property in
 viewport attributes, it is read-write, but changing it does have no effect
 in the viewer.  Attaching test script.

 Here is a blog post about what Safari does: http://www.webkit.org/blog/55
