why 4?

Done.
This is used to vertically center text. Each decoration had its own constant for
this so I've move this out to a common constant
(LocationBarDecoration::kTextYInset).

where do u handle the long query string scenario?
on win/cros, i hide search token if padding between end of query and beginning
of search token is < 20px (which is a predefined views const).

[sail, 2013/01/27 21:11:07]

Done.
My original patch didn't have this functionality. I've added it to
autocomplete_text_field_cell.mm CalculatePositionsHelper().
