not in the same gigantic file.

Nit: Don't need to declare consts/enums atop the function; I would generally
suggest declaring directly above where these are used.  Sometimes this also
allows you to eliminate the declaration of a constant without losing clarity;
example from elsewhere in this file:

  const int kHeaderBuiltinBottomPadding = 4;
  const int kSeparatorTopPadding = ConstrainedWindowConstants::kRowPadding -
      kHeaderBuiltinBottomPadding;
  ...
  grid_layout->AddPaddingRow(0, kSeparatorTopPadding);

-->

  const int kHeaderBuiltinBottomPadding = 4;
  grid_layout->AddPaddingRow(0,
      ConstrainedWindowConstants::kRowPadding - kHeaderBuiltinBottomPadding);

(several places across file)

[please use gerrit instead, 2012/10/16 00:12:23]

necessary constants closer to where they are used. Done.
